AT02 Series

Product catalog summary

Product Overview: The DMS VCSEL Illuminator AT02 Series by Focuslight is designed for applications such as Driver Monitoring Systems, Face Recognition, Lighting, and 3D Sensing. It features an automotive-grade glass diffuser and offers a wide field of view up to 160° in a standard 3235 package.

Specifications: The product specifications include a centroid wavelength of 940 nm, output power greater than 4 W for the FL-AT02-5-940-HxV model and greater than 2.5 W for the FL-AT02-3-940-HxV model. The field of view (FOV) is specified as 120° x 20° or 120° x 60° (Top Hat), and 60° x 45° (Cos-2). The spectral width is less than 3 nm, with a wavelength temperature coefficient of 0.08 nm/°C.

Electrical Parameters: The threshold current is less than 0.7 A for the FL-AT02-5-940-HxV and less than 0.32 A for the FL-AT02-3-940-HxV. The operating current is 6 A and 3.8 A respectively, with a forward voltage of less than 2.5 V. The slope efficiency is greater than 0.8 W/A, and the power conversion efficiency is 32%.

Photodiode (PD) Specifications: The PD forward voltage ranges from 0.5 to 1.3 V, with a reverse breakdown voltage of 35 V. The reverse dark current is between 2-10 nA, and the junction capacitance is 2-10 pF. The peak sensing wavelength is 940 nm.

Operating Conditions: The operating temperature range is from -40°C to 105°C. A non-condensing environment is required for storage and operation below the ambient dew point.

Intensity Angular Distribution: Graphs provided show normalized intensity distribution for different FOVs, indicating performance across various angles.
