Avalanche Photodetector Modules
[ InGaAs & Si : 1800 - 200 nm, kHz - GHz ]

 

These modules are ideal for low-level CW, heterodyne (modulated), or pulsed photodetection. They feature a wide selection of ultra-low noise high-speed avalanche photodiodes in a variety of photosensitive areas, broad spectral response, and high responsivity with coated optical windows. The amplifiers are selected for low noise and linear response over the operating bandwidth. The output impedance is 50-Ω and some models feature AC/DC output-signal coupling at SMA output connectors. These units are optimized for low capacitance (~ 1pF) low impedance (50-Ω) instrumentation and test equipment. The high-speed units require low capacitance semi-rigid cable connections of < 15 cm for full bandwidth performance. SMA-BNC adapters are optional. They are packaged in small plastic modules for convenient operation. A power entry cable and power switch with LED “ON” indication are standard. Metric and/or SAE mounting holes are provided with recommended-optional nylon hardware.

PLEASE NOTE: Our APD products have internal voltages which can attain 250 VDC.  Extra precaution is absolutely essential to avoid any contact with internal hazardous voltage levels.  These products are NOT TO BE OPERATED WHILE DISASSEMBLED.  We are not responsible or liable in any way for any event or any failure related to high voltage operation of these units.  Plastic hardware can be utilized to mount and hold the module (SAE 8-32 and ISO M4 0.7 threads provided).  Electrical connections (power and signal) should be made and verified prior to connecting and switching power to the module.
