Infrared sensors
Infrared sensors react to infrared radiation. This is electromagnetic radiation with a wavelength between 780 nm and 1 mm, which is invisible to the human eye. However, humans can perceive its warming effect through the skin. This has led to the term “thermal radiation”, which is often used synonymously. We will develop and produce pyrometers or infrared thermometers for you that are ideally suited for point and surface temperature measurement. Thanks to a wide variety of configuration options, these can be used in almost all areas of application.

There are two basic types of infrared sensors:
- Passive sensors that can only receive infrared rays, and
- Active sensors that emit thermal radiation themselves and measure its reflection
The former are used to measure the thermal radiation emanating from an object or living being. This enables different actions to be set in motion, such as turning on lights or triggering an alarm. Active infrared sensors are more common in industrial environments. There they determine, for example, whether an object is in a certain position on a conveyor belt, or they enable contact and non-contact temperature measurements. Further fields of application include quality control of production processes, industrial image processing, as well as circuit board development (electronics development).
Passive infrared sensors consist of four components:
- A transmission medium (atmosphere, vacuum, optical fibers)
- Optical lenses for focusing the IR rays (mostly made of quartz, silicone, polyethylene, germanium, or calcium fluoride, in combination with mirrors made of gold or aluminum)
- An infrared light-sensitive material to detect the IR radiation (e.g. lithium tantalate (LiTaO3))
- Signal processing or amplification, to amplify the signals received from the detector
Active infrared sensors additionally have their own infrared source. This must have a temperature of over 0 Kelvin in order to be able to generate thermal radiation. In most cases, infrared lasers, LEDs, or specific IR wavelengths are used for this.
Our product range of infrared sensors includes the following models:
- Pyrometer
- Video pyrometer
- High-performance series
- IR cameras (compact and precision lines)
The measurement range can be specified from -50 °C to +3000 °C, and the spectral range from 1 µm to 14 µm. In terms of detectors, our selection extends from thermopiles to InGaAs and FPA to CMOS. Our temperature sensors and thermal imaging cameras thus enable flexible and cost-saving use in a wide variety of industries such as:
- Automotive
- Glass
- Metal
- Plastics processing
- Early fire detection
- Medicine / life sciences
- Maintenance / servicing
- Solar and semiconductor
Whether during lamination of vehicle interiors, in blown film extrusion, or injection molding temperature measurement, infrared sensors ensure reliable operation and accurate readings. They can be used for functional testing of assembled circuit boards as well as for workpiece control in drop forging, or for inductive heat treatment of metals.
