Optical Sensors

product information

<< to overview

We offer a wide variety of optical sensors like photodiodes, phototransistors, interrupters and reflection sensors. Moreover, we can supply also infrared LEDs which are an important counterparts to photodiodes and phototransistors in many optical sensor applications. In some applications, optical sensors are required which show a similar spectral sensitivity compared to the human eye. For such applications, ambient light sensors are a suitable solution. Further pyrosensors and Fresnel-lenses are presented in this chapter which are used for movement detectors.
