Balanced differential photodetector PDD001-°°-λ
The photodetector supplied with a MOGbox diode laser controller is available separately. In standard configuration, it provides a balanced differential Si-PIN photodiode pair, with 720kHz bandwidth (–3dB) and very low noise. Standard diode options include 400–1100nm or 740–1100nm (solar blind) sensitivity, ±10, 20 or 75° degree field of view. Contact us if you are working with Yb+ and would like our newly sourced 350–1120nm diodes, which are up to 8x more sensitive at 369.5nm.
The default photodetector has filtered photodiodes, with transmission from 750 to 1100nm, and a narrow viewing angle (±10°). These are inherently insensitive to laboratory lighting and sunlight, and the narrow viewing angle further reduces background noise. For lasers operating in the visible range, photodiodes with sensitivity down to 400nm can be supplied at no charge. Wider viewing angles of ±20° or ±75° can also be supplied at no charge. Contact MOGLabs if you require operation outside the 400nm to 1100nm spectrum.
°° = ±10°, ±20° ± 75° specifies the field of view
λ=400–1100nm, 740–1100nm specifies the spectral sensitivity
