Absolute Specular Reflectance Measurement - Especificações
Absolute Specular Reflectance Attachment
ASR series
This attachment measures the absolute reflectance of the specular reflected light. It is used to measure the absolute specular reflectance of a solid sample, such as a mirror, when mounted on the large-sample compartment or SolidSpec. The sample base plate integrating sphere set must also be mounted at the same time. Since measurement is influenced by polarized light when the angle of incidence is large (30°, 45°), the separate polarizer is required to accurately perform measurement.
- For UV-2600series/2700series/3600/3600Plus series, SolidSpec Series
- Approximate size of sample:
25 to 200 mm dia. or 20 x 20 to 150 x 150 mm, thickness up to 30 mm
