Electronics Optoelectronics Semiconductors APD Avalanche LASER photodiode receivers Sensing siliconCMC ELECTRONICS Series of high-response 1064-nm silicon avalanche photodiode (APD) preamplifier modules improve laser applications. The avalanche photodiode receivers boast a high signal to noise ratio and are best in their class in terms of capability to provide accurate and consistent readings under challenging conditions. Both receivers are suitable for ultra-low light signals and can detect longer distances faster, more accurately and consistently than similar products in their category. Customers benefit from fast overload recovery that minimizes receiver damage and usage interruption from high laser burst.
The ROHS-compliant APD receiver module delivers a minimum of 1000kV/W responsivity. Device’s high-density microcircuit combined with advanced optoelectronics, nanosecond recovery from laser bursts without damage enables the receiver to detect low optical signal powers in femtowatt range at high temperatures.
