The wavelength range of the LMS-6600TR is 350-950nm. It integrates the functions of spectrum, transmittance, saturation, reflectance, L, A, B, etc. It uses a 5-inch large screen to display measurement parameters and curves in real time. It is easy and quick to use and can directly test products such as materials and lenses.

Measurement:
