BARLIGHT 3A from Otsuka Optics uses seven high-brightness LEDs arranged in parallel to create planar illumination for surface inspection. Its focused beam emphasizes surface flaws and is ideal for quality control tasks. This lighting can be used alone or paired with magnifiers or optical tools.

LED Light For Checking Surface Flaws BARLIGHT 3A Otsuka Optics

Otsuka Optics’ BARLIGHT 3A enhances flaw detection by projecting a uniform LED light across workpieces. Designed without adjustable beam or dimming, it offers stable, consistent illumination for reliable surface inspection. Its compact form and indoor-rated protection make it suitable for industrial environments.

Features

Flat Beam LED Illumination

Parallel high-brightness LEDs create planar light to emphasize surface irregularities.

Incandescent-Colored Model (A)

Uses warmer LED color to suit varying worker eye comfort and material contrast.

Surface Flaw Emphasis

Designed specifically to highlight scratches, dust, dents on flat surfaces.

Auxiliary Use With Magnifiers

Can combine with optical inspection tools to improve defect detection.
