C5658 APD module
●APD module C5658 is a highly sensitive photodetector consisting of a Si APD (avalanche photodiode), a bias power supply and a low-noise amplifier, all integrated into a compact case. The APD used has an effective active area of φ0.5 mm to allow efficient coupling to a light beam in applications such as spatial light transmission. The APD internally multiplies the photocurrent to produce an ample gain (set to 100 times for C5658) and also features high-speed response, achieving detection limits up to 1 GHz wideband and -48 dBm (16 nWr.m.s.) noise level in combination with the low-noise amplifier. C5658 also incorporates a thermosensor and a temperature-compensated bias power supply necessary for stable operation of the APD. Highly sensitive optical measurements can be made just by supplying +12 V to C5658.
●Feature:
■High-speed response and high sensitivity
■Flat frequency characteristics
■Compact and lightweight
■Single power supply operation
