THORLABS DET10A Operating Manual

DET10A Operating Manual – High Speed GaP Detector
Description:
The Thorlabs DET10A is a ready-to-use high-speed photo detector. The unit comes complete with a photodiode and
internal 12V bias battery enclosed in rugged aluminium housing. The DET10A includes a removable 1" optical
coupler (SM1T1), providing easy mounting of ND filters, spectral filters, fiber adapters (SMA, FC and ST style), and
other Thorlabs 1" stackable lens mount accessories.
The DET10A includes two #8-32 tapped mounting holes with a 0.25" mounting depth, while the DET10A/M has two
M4 tapped mounting holes. A 12V A23 battery is included.
