Infrared camera with incredible 8 µm optics

03.02.2024/640/XNUMX | The structures of electronic assemblies are becoming ever smaller and are very compact. So that the infrared camera PI XNUMXi from Optris measures temperatures precisely and geometrically, even in chip-level structures, it has been equipped with the new Microscope optics MO2X equipped with 2x magnification.

High temperatures have a negative effect on the lifespan of Electronic components and assemblies. The accelerated aging of many semiconductor materials at elevated temperatures may be caused by a poor electrical connection due to the increased contact resistance. However, elevated temperatures can also occur within complex semiconductor components such as processors.

The geometric resolution of the thermal imaging camera is an incredible 8 µm with the new optics. 4x4 pixels are required for exact temperature measurement (MFOV). This means you can now create objects with a Size of only 34 µm measure. This means that even tiny structures can be analyzed at chip level. The thermal resolution reaches a very good value of 80 mK. The focus of the optics allows you to work at a distance of 15 mm from the object being measured.

The optics on the PI series cameras are easily interchangeable. This means that the system can be used flexibly for various measuring tasks. A high quality one Microscope stand with fine adjustment is included in the scope of delivery. Together with it, microelectronic assemblies can be examined very easily.

Infrared camera in a protective housing for hot and cold outdoor areas


Optris infrared camera protective housing11.11.2023/XNUMX/XNUMX | the Thermal imager Use under adverse environmental conditions is possible with the Outdoor protective housing by Optris. Very low or high temperatures, dust and humidity place high demands on the Electronics. Special measures are therefore often required to protect sensitive devices. This also applies to the thermal imaging cameras of the PI and Xi series from Optris.

So that they can easily withstand adverse conditions, the specialist for non-contact thermography has developed a new outdoor housing that optimally protects the sensitive devices. Compact, the housing offers the possibility for the first time Thermal imaging camera and HD video camera to be integrated together in one system. A compact USB server is also integrated into it.

Purging attachment protects against dust and moisture

The IP66 housing can be used in damp and dusty environments without any problems. An electric heating element is integrated so that the infrared camera can be used in very low temperatures. This switches on automatically below +15 °C. A fan distributes the warm air evenly in the housing of the thermal imaging device. This means that the thermal imaging camera can also be used in a temperature measuring range of up to -40 °C. In contrast, a measuring range of up to +50 °C is possible in warmer areas.

The optionally available air purge attachment continuously flushes the protective window of the housing with compressed air. This prevents dust or condensing moisture from collecting there. The infrared camera therefore always has optimal visibility and measures reliably.

Bottom up thermal imaging inspection system for glass tempering

Optris temperature measurement glass hardening


09.05.2022 | For the high energy efficiency in Buildings become default Low-E glass window and facade elements used. Designed as multi-pane insulating glass, the windows have a coated side with a very low emissivity. This is a major challenge for infrared measuring devices. Because they traditionally measure the glass temperature from above when the panes are moved out of the furnace during the glass tempering process.

The new bottom up system solves this problem while tracking one new approach: By installing two thermal imaging cameras below the prestressing line, they always measure the temperature on the uncoated glass side with high emissivity (1600 pixel scan line resolution and max. field of view of 111° / 4,3 m scan width). Both infrared cameras are protected in the event of glass breakage by a CTlaser 4M pyrometer from Optris in the digitally controlled optics protection system (DCLP - two automatic shutters).

The Bottom Up Glass Inspection System for Glass Tempering Lines is easy to install because it already pre-assembled is. The thermal imaging camera system is suitable for the tightest of installation spaces. It can be precisely positioned mechanically. The old, bulky line scanners previously used are no longer necessary. The scan line can be precisely aligned using the software supplied.

Thermal imaging camera with car hotspot finder

Optris infrared camera31.05.2021/XNUMX/XNUMX | "In addition to the usual use of an IR camera with PC and software, the thermal imaging camera also works fully autonomously as a smart, target-seeking pyrometer with analog or alarm output," explains Torsten Czech, Head of Marketing at Optris.

The thermal imaging cameras of the Xi 410 series have a Fast Ethernet interfaceThe infrared cameras can be conveniently powered via PoE. This allows for uncomplicated installation of the thermal imaging cameras even at a greater distance from the PC.

Thanks to the integrated in the infrared cameras Auto hotspot finder function The temperature of moving objects is measured reliably. The thermal imaging device does not need to be readjusted. If there is a problem with the connected PC or the network connection fails, the camera also creates the thermal image result fully autonomously and ensures a seamless and reliable alarm in the event of a problem being detected.

Thanks to this property, the Xi 410 thermal imaging device is ideally suited for all safety-related applications such as preventive Fire protection or the condition monitoring on machines and systems.

OEM cameras with motor focus

In addition to the Ethernet interface The Xi 410 thermal imaging camera has a USB 2.0 port for quick configuration of important parameters. It also has a direct 0/4-20 mA analog output. Up to 9 freely definable measuring fields of the thermal imaging camera can be further processed as analog outputs (either 0/4-20 mA or 0-10 V) via an external process interface. Over Relais These can be issued as an alarm - ideal for use as OEM cameras.

The thermal imaging cameras of the Xi 410 series are, like the other two series of the Xi series, also equipped with a motorized focus. This allows convenient focusing from a distance using the free PIX Connect software.

The Resolution of the thermal imaging cameras is 382 pixels x 240 pixels at a frame rate of 25 Hz. The Xi 410 was designed for Measurement of temperatures calibrated from -20 ° to 900 ° C. When ordering a thermal imaging camera, customers receive a ready-to-use package Including mounting nut, mounting bracket, software, Ethernet and USB connection cable.

Thermal imaging camera measures glass temperature during glass hardening

Optris glass temperature


24.03.2021/XNUMX/XNUMX | The physical properties of Flat glass can be changed through targeted heat treatment. For example, toughened safety glass (ESG) is produced through thermal tempering. The glass panes are heated evenly in a furnace to a temperature of more than 600 °C. They are then cooled down rapidly in a cooling section by blowing air onto them. Optris has developed an infrared system for a requirement such as monitoring the glass temperature and temperature distribution during this process.

In the process of Tempering In order to achieve the desired quality of the glass panes, the temperature in the oven determined for the respective type of glass and glass thickness must be precisely maintained. In addition to the exact temperature, it is also important to ensure that the temperature distribution within the glass panes is as homogeneous as possible. Optris has the complete thermal imaging camera system for quality assurance of this application TD GIS 640 R developed. Based on the PI 640 thermal imaging camera, it can be precisely adapted to any glass tempering system thanks to selectable optics with different opening angles.

Monitor glass temperature on window glass

Optris infrared cameraFor energy-efficient buildings today, the so-called Low-E glass for windows and facade components used as standard. The windows are designed as multi-pane insulating glass. They consist of a coated side with a very low emissivity. The coating ensures reduced heat radiation in winter and less heating of the rooms due to solar radiation from outside in summer.

The low emissivity of the insulating glass windows poses a major challenge for the infrared measurement technology used. The new thermal imaging camera system Top Down GIS 640 R was specially configured for this. A thermal imaging camera type PI 640 is installed at the oven exit for measurements above the glass on the coated side. It measures the temperature distribution of the individual glass panes in high resolution and very quickly across the entire width of the system. Below the glass on the uncoated side, a pyrometer type CT G5L reproducibly measures the exact glass temperature.

Maintenance intervals extended considerably

Optris glass productionThe individual pixels of the infrared camera image are referenced to this measured value. This allows an automated emissivity correction for standard glass and Low-E glass. In addition to the temperature distribution, the IR system also determines the glass surface. The pyrometer and thermal imaging camera are equipped with digitally controlled optics protection. These shutters significantly reduce the need for cleaning the optics. There is no need for additional and time-consuming blowing with compressed air.

Optris offers this for simple electrical installations on a glass tempering system Top Down GIS 640 R System pre-assembled. The complete system consists of a thermal imaging camera, pyrometer, shutter and a compact switch cabinet with electronic and control components as well as cables.

FAQ

What is a thermal imaging camera?

An Thermal imaging camera is an infrared camera for non-contact temperature measurement of a specific measurement object. It can be used to show the distribution and change of temperatures. The evaluation of the data is based on infrared radiation. The thermal radiation emitted by the measurement object is focused on an infrared detector. The resolution (in pixels) of thermal imaging cameras is much lower than that of visual cameras. Thermal imaging cameras are suitable for displaying temperature distributions or temperature changes in larger areas. 

How does an IR camera work?

An infrared camera, also known as an IR camera or thermal imaging camera, captures thermal images by recording the infrared radiation (heat radiation) emitted by objects. How it works can be explained in just a few steps:

  1. detection of infrared radiation: Any object whose temperature is above absolute zero emits infrared radiation. The IR camera is equipped with a sensor that detects this radiation.
  2. Create a thermal image: The captured infrared radiation is converted into an electronic signal. This signal is then processed to produce a thermal image that represents the temperature differences of the observed scene in different colors.
  3. Presentation and analysis: The thermal image is displayed on the camera display and can be used for further analyzes such as temperature measurements, pattern recognition or diagnostics.

Where are thermal imaging cameras used?

Thermal imaging cameras are used in many areas, e.g. B. in the Buildingsthermography, in the preventive maintenance of machines, in the Medical Technology or in the Safety Technology.

How far can thermal imaging cameras see?

The range of a thermal imaging camera depends on several factors:

  • SensorResolution and sensitivity: Higher resolutions and more sensitive sensors can detect finer temperature differences from greater distances.
  • Objectsize and TemperatureDifference: Larger and warmer objects can be detected from a further distance than smaller or less warm objects.
  • optics the camera: Lenses with a longer focal length enable a better view of distant objects.
  • Atmospherice Conditions: Humidity, smoke, fog and other atmospheric disturbances may reduce range.

In general, thermal imaging cameras can detect objects at a distance of several hundred meters; in some cases, especially in the category of high-performance cameras and under ideal conditions, the range can be several kilometers.
