LWIR Transmission and Refection Measurement of Plano Optics at Normal and Variable Angles of Incidence
Accurate and reliable infrared spectral measurements of optical coatings are one of the most critical challenges today. Optical manufacturers around the world specify increasingly sophisticated IR coatings for their planar optics focusing on better detection and identification of objects at long distances. Often, the production capabilities for obtaining optical coatings are well ahead of the existing metrological capabilities for certifying their quality.
The PHOTON RT 7512 spectrophotometer is a unique instrument specially designed to effectively meet these challenges. The instrument allows measuring the transmission and reflection of coatings designed for LWIR. An unsurpassed feature of the PHOTON RT 7512 is the ability to carry out automatic measurements at variable angles of incidence up to 60 degrees in polarized light. These non-trivial tests are supported with the built-in feature which accurately compensates for beam displacement at high angles and ensures S-pol and P-pol results in just a few minutes. Maximum thickness of the sample can be a record 40 mm.
