DET02AFC Operating Manual — Fiber Input Si Photodetector
Description:
The DET02AFC is a ready-to-use, high-speed Si photodetector for use with FC/PC connectorized fiber optic cables
in visible wavelength optical systems. The unit comes with an FC/PC bulkhead connector, detector, and 12V bias
battery enclosed in a compact aluminum housing. The FC/PC connector provides easy coupling to fiber-based light
sources. The output uses an SMA jack to minimize size and maximize frequency response. The bandwidth is
1.2GHz and will operate over the spectral range of 400-1100nm. A NIR version, the DET01CFC, is also available
and operates in the 800-1700nm spectral range.
The DET02AFC includes one #8-32 tapped mounting hole with a 0.25" mounting depth, while the DET02AFC/M has
one M4 tapped mounting hole with a 6.35mm mounting depth. A 12V A23 battery is included.

Page 2: Operation
Unpack the optical head and install the battery as described in “Battery Replacement.” • (Optional) Install a Thorlabs TR series ½″ diameter post into one of the #8-32 (M4) tapped holes, located on the bottom and side of the sensor, and mount into a PH series post holder. -
Page 3: Battery Replacement
There are no serviceable parts in the DET02AFC optical sensor. The housing may be cleaned with a soft damp cloth. If you suspect a problem with your DET02AFC, please call Thorlabs and an engineer will be happy to assist you. - Page 4 Waste treatment on your own responsibility If you do not return an end-of-life unit to Thorlabs, you must hand it to a company specialized in waste recovery. Do not dispose of the unit in a litter bin or at a public waste disposal site.
