New with Integrated Filter

Rangefinding using the time-of-flight (TOF) principle is one of the primary applications for silicon avalanche photodiodes (APD), with widespread application examples from sports optics through metrological measurement to speed control systems. A short light pulse emitted from a 905 nm laser diode is reflected from the target object and focussed by a collection optic onto the APD chip. A band pass filter is invariably incorporated within the optical path to enable the optimum signal-to-noise ratio to be achieved by suppressing background light. The SARF series of APDs features this filter integrated into the compact APD housing, as well as an APD chip with optimum sensitivity at 905 nm.  The diameter of the ative area is 500 µm.

The advantages are:

• Cost saving by eliminating an extra filter
• Extremely compact design
• Optimum performance at 905 nm

The APDs are offered in a compact, low profile TO-46 can or alternatively in an SMD package.
