Laser Components develops APDs for rangefinding and communications

IAL Series of InGaAs avalanche photodiodes

Laser Components has expanded its range of InGaAs avalanche photodiodes (APDs) with the new IAL series, which 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 800nm and 1,700nm and reach their peak sensitivity at 1,550nm.  In the range from 1,000nm to 1,600nm, their quantum efficiency is 70%. 

The active area of the IAL APDs has a standard diameter of 200µm. 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 fibre-coupled version upon request. 

Along with distance measurement, Laser Components recommends the IAL series for numerous other applications such as free-space optical communications and high-resolution optical coherence tomography.
