Description
The LTG85LARYK8 is a Class 1, 850 nm continuous-wave (CW) structured-light laser module integrating a single-mode 850 nm laser diode, a precision Diffractive Optical Element (DOE), an aspherical lens, an adjustable-focus optical design, and a fail-safe Automatic Power Control (APC) circuit designed to support IEC 60825-1 Class 1 operation driven by a standard 3–5 VDC supply.
The laser module projects either 10,000 or 30,000 random dots over an 80° × 64.4° FOV, with a DOE contrast of ≥10 and ≥3, respectively. The adjustable-focus optical design enables optimization of the projected dot pattern for the desired working distance, while CW operation and APC regulation provide stable, consistent illumination and repeatable optical output. The LTG85LARYK8 is ideally suited for indoor active-stereo 3D sensing, 3D depth sensing, and other optical sensing applications.
