DONGRU DR82B blue-violet light transmittance Tester

Introduction

DR82B Blue-Violet Light Transmittance Tester is a small desktop optical transmittance Tester, which specializes in the optical transmittance detection of various myopia spectacle lenses, reading glasses lenses, display lenses and anti-blue light materials. This instrument adopts a three-in-one optical path design, which can measure four sets of data of visible light, blue light, violet light transmittance and UV400 at one time, and can also measure four sets of data of visible light transmittance, blue light blocking rate, violet light blocking rate + UV400 at one time.

This instrument mainly uses visible light source, 430nm blue light source and 395nm violet light source to irradiate the measured transparent substance, the sensor detects the incident light intensity of the three light sources and the light intensity after passing through the measured transparent substance, the ratio of the transmitted light intensity to the incident light intensity is the transmittance, expressed as a percentage, 1-transmittance = blocking rate. The instrument is exquisite, small and beautiful, ready to measure, accurate data, suitable for field testing or laboratory use.

Note: This instrument is not suitable for measuring the transmittance of printed, milky white and matte materials; The instrument should not be used in sunlight or bright light.

Features
