Description
The LTG85LARYK8T is a Class 1, 850 nm continuous-wave (CW) structured-light laser module integrating a precision Diffractive Optical Element (DOE), a glass aspherical lens, an adjustable-focus optical design, a single-mode 850 nm laser diode, and a fail-safe Automatic Power Control (APC) circuit designed to support IEC 60825-1 Class 1 operation, with TTL modulation from DC to 10 kHz.
The laser module projects either 10,000 or 30,000 random dots over an 80° × 64.4° (H x V) field of view (FOV), with a DOE contrast ≧10 or ≧3, respectively. The adjustable-focus optical design enables optimization of the projected dot pattern for the desired working distance. The APC circuit maintains controlled optical output for stable and repeatable performance in indoor active-stereo 3D sensing, 3D depth sensing, and other optical sensing applications.
