The A-CUBE-S1500-01 from Laser Components is a Silicon Avalanche Photodetector that operates at a wavelength of 400 nm - 1000 nm. It has a responsivity of 270 MV/W (540 nm), 400 MV/W (650 nm), and 500 MV/W (905 nm). This APD has a noise equivalent power (NEP) of 11 fW/rt(Hz) (540 nm), 7.5 fW/rt(Hz) (650 nm), and 6 fW/rt(Hz) (905 nm). It has an active area diameter of 1.5 mm with a bandwidth from DC to 1 MHz. This APD has a peak sensitivity of 905 nm and an output noise density of 3000 nV/rt(Hz).
The A-CUBE-S1500-01 has a maximum input referred noise density of 0.3 pA/rt(Hz) and an irradiated power (at 905 nm, 50 Ohms) of 3 nW. It has a matched preamplifier, an integrated high voltage supply, and in-built temperature compensation circuitry. This APD can be controlled via an RS-232 interface and supports optional optical fiber coupling & FC connector. It requires a DC supply of 12 V and is available in a compact module that measures 40.6 mm x 40.6 mm x 49.78 mm. This APD is ideal for APD evaluation, range finding, LiDAR, optical communication systems, spectroscopy, fluorescence, and medical applications.
