AT01 Series

Product catalog summary

Product Overview: The DMS VCSEL Illuminator AT01 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 a wide field of view up to 160° in a standard 3535 package.

Specifications: The module type FL-AT01-3-940-HxV operates under test conditions of 300µs, 300Hz, 9% DC at 25°C. Key optical parameters include a centroid wavelength of 940 nm, output power greater than 2.5 W, and a spectral width FWHM of less than 3 nm. The device has a typical field of view of 120° x 20° (Horizontal x Vertical) and a wavelength temperature coefficient of 0.08 nm/°C.

Electrical Parameters: The threshold current is less than 0.5 A, with an operating current of 3.5 A and a forward voltage of less than 2.5 V. The slope efficiency is greater than 0.8 W/A, and the power conversion efficiency exceeds 32%.

Operating Conditions: The device operates within a temperature range of -40°C to 105°C and requires a non-condensing environment for storage and operation below the ambient dew point.

Contact Information: For further details or special requirements, customers are encouraged to contact Focuslight Technologies Inc. at their Xi’an, Shaanxi location via phone, fax, or email.

Graphical Data: The intensity angular distribution graph illustrates the normalized intensity across angles, highlighting the 120°x20° field of view in both horizontal and vertical orientations.
