Lens Transmittance Tester

The lens transmittance tester works by illuminating a sample with a light source, while a sensor receives the transmitted light and converts it into an electrical signal to calculate the percentage of light transmission. It is used to test the transmittance performance of optical materials such as glasses and goggles, ensuring compliance with usage standards.
Selection
When selecting, ensure the measurement wavelength range covers the application requirements, check the instrument's accuracy and repeatability errors, evaluate whether the sample clamping method is compatible with the lens shape, verify the validity of the calibration certificate, and consider the convenience of the operation interface and compatibility of data output formats.
