The LTG66LARYK8 is a Class 1 660 nm continuous-wave structured-light laser module featuring a precision random-dot DOE, glass aspherical lens, adjustable focus, single-mode laser diode, and fail-safe APC. Available with 10,000 or 30,000 random dots across an 80° × 64.4° FOV, it delivers stable, repeatable structured illumination for OEM integration, machine vision, industrial inspection, and optical sensing.
LTG66LARYK8
Description
The LTG66LARYK8 is a Class 1, 660 nm continuous-wave (CW) structured-light laser module integrating a precision Diffractive Optical Element (DOE), a glass aspherical lens, an adjustable-focus optical design, single-mode 660 nm laser diode, 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 ≥8 and ≥2, respectively. The adjustable-focus design allows the projected pattern to be optimized for the target working distance, while CW operation and APC control provide stable, consistent illumination and repeatable optical output. The LTG66LARYK8 is ideally suited for machine vision, industrial inspection, and other optical sensing applications.
