Variable-angle Reflection Sampling System
|
The
RSS-VA Variable-angle Reflection System is an opto-mechanical
device that couples to spectrometers
and light sources to measure specular reflection of optical substrates
from 200-2000 nm, at varying angles of incidence. The RSS-VA is available for $1470.
The RSS-VA's chamber has two ports for SMA 905-terminated optical
fibers -- one to illuminate the sample, the other to collect the signal
and send it to the spectrometer -- and a 3-point surface mount for holding
the sample in a fixed position.

|
 |
Inside the chamber, optics mounted on a carrier can be adjusted to set
the angle of incidence from ~10° to ~50°; a thumbscrew holds the optical
assembly at a fixed angle. When used with Ocean Optics spectroscopic
systems and specular reflectance standards, the RSS-VA is an especially
versatile variable-angle device for characterizing a variety of optical
substrates, especially metallic and dielectric coatings. |
To measure optics 10 mm x 3 mm or smaller with the RSS-VA, we offer the
RSS-VA-ADP Sample Holder for $104.
