The Correct Material for Infrared (IR) Applications

Some materials can be used for either IR or visible applications, most notably fused silica, BK7 and sapphire; however, the performance of an optical system can be optimized by using materials better suited to the task at hand. To understand this concept, consider transmission, index of refraction, dispersion and gradient index. For more in-depth information on specifications and properties ...

IR (Infrared) Obstacle Detection Sensor Circuit

2015-02-02· Thermal infrared sensors use infrared energy as the source of heat and are independent of wavelength. Thermocouples, pyroelectric detectors and bolometers are the common types of thermal infrared detectors. Quantum type infrared detectors offer higher detection performance and are faster than thermal type infrared detectors.

Beginners guide to IR sensor and How to use Ir sensor with ...

2018-10-06· The single potentiometer on most of the IR sensors is used to set the sensitivity of the sensor or the distance up to which it detects the obstacle. So by rotating the potentiometer you can set the detection distance. There are generally two LEDs on the IR sensor, one is a power indicator and the other one is the output/obstacle indicator. Different versions of IR sensor…
