Installation and Operation Instructions
Description
The RSS-VA Variable-angle Reflection System is an optomechanical device that couples to
spectrometers and light sources to measure the specular reflection of optical substrates from 200-
1100 nm, at varying angles of incidence.
The RSS-VA features two SMA 905 Connectors – one to illuminate the sample and one to collect the
reflected light and transfer it to the spectrometer. It also features a 3-point surface mount that holds the
sample to be measured in a fixed position during the integration period.
Inside the black anodized chamber, the RSS-VA features optics mounted on a carrier that you can
manually adjust to set the angle of incidence from approximately 10° to 50°. Once adjusted, a
thumbscrew holds the optical assembly at the fixed angle.
When used with Ocean Optics spectroscopic systems and specular reflectance standards, the RSS-VA
is a versatile variable-angle device for characterizing a variety of optical substrates, such as those
featuring metallic and dielectric coatings.
