Otsuka Optics’ BARLIGHT3 delivers evenly distributed LED light with adjustable divergence (6°–30°) and dimming from 100 % to 50 %. This illumination unit improves flaw detection both as a standalone inspection light and as auxiliary lighting for magnifiers, enhancing contrast for quality control work.

LED Light For Checking Surface Flaws BARLIGHT3 Otsuka Optics

The BARLIGHT3 LED surface flaw light uses parallel-arranged high-brightness LEDs and lenses to cast flat light rays onto surfaces. With dimming and beam angle adjustment, it adapts to diverse inspection needs from flat panels to slightly three-dimensional objects, making it ideal for precision inspection.

Features

LED Illumination

Bright white LED array (7 LEDs) for clear surface inspection.

Adjustable Beam Angle

Divergence angle adjustable between 6° and 30° to suit surface geometry.

Dimmable Lighting

Integrated dimming function (100 % → 50 %) to reduce surface reflection.

Versatile Mounting Options

Optional tilt stand, double tilt stand, free arm, or handheld grip available.

Auxiliary Use

Can be used alone or with optical inspection tools to enhance defect detect
