High-resistance power diodes are used in intensity measurements and as detectors in optical fibers. They are less expensive than APDs, but are also less sensitive.
Highly-sensitive PIN Detector Modules
P-CUBEs: Cubes with a built-in photodiode that can be easily integrated into optical bench setups.
PIN Detector Modules
For easy integration into optical bench setups, CUBE components are available. The P-CUBE series houses an integrated very low-noise and sensitive PIN photodiode inside a compact cube.
The CUBE can be attached directly to a rail system. With an edge length of 40 mm, this constitutes standard dimensions.
Three types of P-CUBEs are available:
- Spectral range: 190 nm – 570 nm
For wavelengths between 190 nm and 570 nm the P-CUBEs are equipped with a low-noise GaP photodiode.
- Spectral range 200 nm – 1050 nm
Blue-enhanced Si photodiodes cover a large spectral range. They detect radiation between 200 nm and 1050 nm.
- Spectral range 800 nm – 2200 nm
An NIR-enhanced InGaAs PIN photodiode is used for infrared wavelengths. The detection range extends from 800 nm to 2200 nm.
The output signal of the photodiodes is obtained using a BNC connector in all P-CUBEs and can be directly fed into the programmable iAMP-700 current amplifier.
The P-CUBE is also available with an optical FC connector.
