Cost-efficient InGaAs APDs
LASER COMPONENTS expands its range of InGaAs APDs (avalanche photodiodes) with its new IAL series. Compared to the established IAG series, the world's best APD with a Vbr-Vop of up to 7V, the IAL series offers a Vbr-Vop of about 4V. In this working voltage range, gains of greater than 20 can be achieved at the lowest noise values.
These low-cost detectors are mainly used in laser range finding applications. They cover a wavelength range between 800 nm and 1700 nm and reach their peak sensitivity at 1550 nm. In the range from 1000 nm to 1600 nm, their quantum efficiency is 70%.
The active area of the IAL APDs has a standard diameter of 200 µm. Variations with D=80µm and 500µm are also available as options. The components are manufactured in hermetically sealed TO-46 packages or as SMDs in M6 packages and are also available in a fiber-coupled version upon request.
Along with distance measurement, LASER COMPONENTS recommends the IAL series InGaAs APDs for numerous other applications such as free-space optical communications and high-resolution optical coherence tomography.
