XFPD Photodiode Laser Power Detector
Embedded photodiode detectors covering 350–1100 nm with automatic ambient-light cancellation and analog output.
An embedded photodiode detector covering 350–1100 nm, small enough to sit inside a laser module and immune to the room lights around it.
Why this series
- Spectral coverage 350–1100 nm, wavelength calibratable
- 6 mm and 10 mm apertures with saturation at 10 mW and 15 mW
- Automatic ambient-light cancellation — no dark box required
- Raw responsivity 0.52 A/W at 800 nm
- Works with CW and pulsed sources; maximum pulse energy 3 µJ
- Response time under 0.2 s — fast enough for live monitoring
- Analog interface, 1 g and 2 g weight
