INSIZE 5824-LT03 Lens Transmission Meter, 0.5mm Aperture

The INSIZE 5824-LT03 is a lens transmission meter for checking infrared transmittance, such as IR ink holes in phone lenses, remote-control windows and IR-CUT filters, through a 0.5mm measuring aperture. INSIZE states it reads visible light at a 550nm peak wavelength alongside infrared at 850nm and 940nm in one three-in-one optical path, at 0.1% resolution and plus-or-minus 2% accuracy on colourless, uniform transparent material across 0-90% transmittance. Results appear on a 3.5-inch LCD with automatic high/low limit judgement and can be exported as an Excel report for batch testing. It runs on DC5V/1A, weighs 1570g and includes an L-shaped positioning plate and software.
