6. Turn on the PDA10DT using the power switch located on the top side of
the detector.
7. Install any desired filters, optics, adapters, or fiber adapters to the input
aperture.
CAUTION
The PDA10DT was designed to allow maximum accessibility to the
photodetector by having the front surface of the diode flush with the outside of
the PDA housing. When using fiber adapters, make sure that the fiber ferrule
does not crash into the detector. Failure to do so may cause damage to the
diode and/or the fiber. Installing an SM1RR Retaining Ring (included) inside the
1" threaded coupler before installing the fiber adapter will prevent damage.
8. Apply a light source to the detector. Adjust the gain to the desired setting.
Note:
Allow a minute for the TEC controller to stabilize the temperature.
For best results, allow the unit to warm up for about 30 minutes.
CAUTION
Saturation of the output signal may cause damage to the InGaAs detector
element.
