The LTG85LAR-Y-K8 is a Class 1 850nm CW random-dot DOE structured light laser module featuring adjustable focus, 10,000 or 30,000 projected dots, and an 80° × 64.4° FOV for indoor 3D sensing, machine vision, and optical sensing.
LTG85LAR-Y-K8
Description
The LTG85LAR-Y-K8 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 adjustable-focus optical design, and an IEC 60825-compliant Automatic Power Control (APC) circuit 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.
CW operation provides continuous, stable illumination during camera exposure for efficient photon collection and consistent dot intensity. The APC circuit maintains controlled optical output for stable and repeatable performance in indoor active-stereo 3D sensing, machine vision, and other optical sensing applications.
