The SAR500x Si-APD has a 500 µm detector chip with a “reach through’’ structure. This structure is responsible for a high sensitivity in the spectral range of 400 nm to 1100 nm and simultaneously for extremely fast rise and fall times, typically of 450 ps. The SAR500X is delivered in a hermetically sealed TO-18 can. The SAR500X is designed for a wide range of uses, including laser rangefinding and optical communication with data transfer rates of up to 1 Gbit/s.
Such uses make sense where high speed and/or a high sensitivity are necessary.
The SARP500x is a SAR500S type APD that has been selected for extremely low noise (typically 100 fA/sqrt(Hz) @ M = 100) and low dark currents. It is therefore suitable for the detection of the smallest amount of light. The SARP500 series can be delivered in a TO-18 can or with a thermoelectric cooler in a TO-37 can. This APD is additionally suitable for use in spectroscopy, fluorescence measurement, medical technology, and LIDAR applications.
