LS108 Blue and Violet Light Transmittance Meter | Anti-Blue-Light Coating Tester
The LS108 blue and violet light transmittance meter evaluates transmission and blocking performance of eyeglass lenses, coatings, organic materials and anti-blue-light materials. Its three-in-one optical path measures visible, blue and violet light transmission or blocking with one alignment. Select the measurement mode for the sample and test standard.
Applications include optical lenses, anti-blue-light coatings and optical materials. Contact our team to confirm the configuration and test conditions for your application.

The LS108A Lens Transmittance Meter is designed to test transmittance in mobile phone cover-glass IR ink openings, remote-control windows, IR-cut filters, infrared-technology products, screen protectors and lens materials. Its three-in-one optical path measures transmittance at 550 nm visible light, 850 nm infrared and 940 nm infrared with one alignment. The 1 mm measuring aperture is suitable for samples larger than 1 mm. The meter supports incoming inspection of optical components, process quality control, batch comparison and pre-shipment checks.

The LS108D lens transmittance meter is designed to test infrared transmittance through IR-ink openings in phone cover glass, very small light-transmitting apertures, remote-control windows, IR-cut filters, screen protectors, and lens materials. Compared with the LS108A 1 mm measuring aperture, the LS108D features a 0.5 mm micro-aperture for testing smaller openings or areas with limited measurement space. Confirm the model according to sample aperture, positioning method, test wavelengths, and quality-control workflow.
