Product Information

Back to top
C-LQ is a sensor for pulse and alternating light with a monolithically integrated photodiode. The device supersedes conventional photoreceivers, such as those in light barriers, for example. At the first stage sensitive changes in the photocurrent are amplified whereas the photocurrents caused by background light are electronically suppressed with over 60 dB (at 100 Hz). The integrated amplifier forms a band-pass characteristic without using any external components. The high pass suppresses ambient light and low frequency alternating light and the low pass reduces high frequency noise. For visible light or near infrared the highest sensitivity for alternating light signals is reached at approximately 150 kHz; for pulse light this is reached at 1.2 µs and upwards. The transimpedance amplification can be selected within a range of approximately 1 M? to 10 M? via the external operating load. iC-LQ is available as a 4-pole TO18 metal can package with a glass lens or flat window and as an optoBGATM package for surface mounting. Customized COB versions are also possible.
