Silicon carbide SiC photodetectors / photodiodes have a spectral response of approximately 210 – 380 nm and are not sensitive to UV radiation outside this region. This makes them ideal detectors in certain applications for monitoring the UV spectrum without the need for solar rejection filters. SiC photodetectors are extremely durable and have been proven to withstand prolonged UV exposure in production quantities in many applications.
No other detector material (e.g. Si, Ti02, GaN or diamond) can offer the unique advantages of IFW’s silicon carbide detectors (SiC) in UV-applications:
- intrinsic spectral response is limited to the range of 200 – 400nm and no additional blocking of unwanted visual and IR-range of radiation is necessary
- proven outstanding long term stability under high doses of UV-C- radiation (up to 1000Wm-2)
- excellent temperature stability, (temperature coefficient Tk<-0,06%/K), stable long term operation of up to +150°C
Silicon carbide SiC photodiodes / photodetectors are offered in TO-18 and TO-5 packages with or without integrated filters for UVA, UVB, UVC, UVBC and UVBC2. Hybrid units with integrated amplifiers are also available.
To avoid damaging photodiodes during soldering and cleaning, consider using sockets.
