MH-380 anti-fog tester

Optical Path

The MH-380 measurement path and operating principle are designed in accordance with international standards to provide highly accurate and consistent results.

The instrument uses a 600 ± 70 nm red laser light source. The laser passes through the sample twice to detect fogging on the lens surface. A high-precision imported laser energy detector with 0.01 Plus accuracy measures and evaluates the sample’s anti-fog performance.
