UV-Vis-NIR VW Absolute Specular Reflectance Accessory
The VW absolute specular reflectance accessory is designed to measure near-normal (7 degree), mirror-like reflectance off sample surfaces such as high-reflectance mirrors or low antireflection mirrors. Applications include determining the degree of polishing of an optical surface and measuring the film thickness of thin coatings.
Configurable in a dual bounce 'W' or single bounce 'V' (known-mirror) configuration, this absolute reflectance technique combines a maximum light throughput accessory with the high dynamic range Cary 4000, 5000, 6000i, and 7000 spectrophotometers to measure samples with very low reflectance such as anti-reflection coatings.
