Description
Atomfair CRI 684 Crystal Refractive Index-Temperature Relationship Measurement Instrument
Product Overview
Atomfair CRI 684 Crystal Refractive Index-Temperature Relationship Measurement Instrument is a co-developed experimental device with East China Normal University. Adopting Michelson interferometry to measure the refractive index temperature characteristics of solid materials, it can accurately plot the refractive index-temperature characteristic curves of lithium tantalate and lithium niobate crystals. The instrument is easy to operate, wide in applicability and high in precision, and can be extended to measure the refractive index temperature characteristics of various transparent solid materials with high popularization value, suitable for physics teaching and engineering optics experiment scenarios.
