Page 4: Chapter 2 Description
Chapter 2: Description Chapter 2 Description The Thorlabs DET10A(/M) is a biased, Silicon (Si) detector designed for detection of light signals ranging from 200 nm to 1100 nm. The unit comes complete with a photodiode and an internal 12 V bias battery enclosed in a rugged aluminum housing. -
Page 5: Chapter 3 Setup
Failure to do so may cause damage to the diode and or the fiber. An easy way to accomplish this is to install a SM1RR retaining ring [included with the DET10A(/M)] inside the 1" threaded coupler before installing the fiber adapter. -
