D320 Low Noise Visible Photoreceiver
- +

Low Noise Visible Photoreceiver (D320-B400K-G10M-DC-FS) based on our low noise current amplifier design deployed in many instruments. Spectral range covers 300-1100nm. It has single gain setting, DC coupled and bandwidth of 400kHz.There are several mounting holes for different mounting orientation. It can be used a standalone instrument or as OEM unit.
Standard package overview. Variations expected between D300 models. Typical color finish red or blue. Optional C-mount adaptor is sold separately.
