LS108D Lens Transmittance Meter | 0.5 mm Micro-Aperture
The LS108D lens meter measures visible-light transmittance of lenses and infrared transmission through IR-ink openings. Its 0.5 mm measuring aperture supports small-area samples. Measurements include 550 nm visible light and 850 nm and 940 nm infrared. Real-time dynamic self-calibration automatically sets the baseline to 100% transmittance after startup.

Lens and IR-Aperture Transmittance Measurement Demo
Both the LS108A and LS108D can measure transmittance through lenses, screen protectors, and IR apertures. For a 1 mm test aperture, consider the LS108A Lens Transmittance Meter. For smaller openings or restricted measurement locations, consider the LS108D. Confirm selection according to aperture size, sample positioning, and test wavelength.
