STAN-HOLDER
Ocean Insight offers specular reflectance standards for measuring shiny surfaces such as machined metals and semiconductor materials and low-reflectivity surfaces such as anti-reflective coatings and thin film coatings. Add a STAN-HOLDER to keep your standards in place and to protect their coatings.
- Convenient holder – optional accessory holds reflectance standards in place
- Benefits — keeps standard securely in place and helps preserve its coating
STAN-SSH Specular Reflectance Standard
Ocean Insight offers specular reflectance standards for measuring shiny surfaces such as machined metals and semiconductor materials and low-reflectivity surfaces such as anti-reflective coatings and thin film coatings.
The STAN-SSH varies in reflectivity from 85%-98% over the 250-2500 nm wavelength range and is available in a version (STAN-SSH-NIST) calibrated to a NIST master standard. The NIST calibration data range is 250-2400 nm.
- Specular reflectance – high specular reflectivity (85%-98% over the 250-2500 nm)
- Calibrated standard – NIST-traceable version also available
- Convenient holder – optional accessory holds standard in place
Engineering:
- Reflectance Material:
- Al mirror on fused silica substrate
- Reflectivity:
- “~85%-90% (250-800 nm) ~85%-98% (800-2500 nm) “
- Spectral Range:
- 250-2000 nm
- Dimensions (Housing):
- 38 mm OD x 19 mm height
- Dimensions (Substrate):
- 31.75 mm OD x 6.35 mm height
- Weight:

STAN-SSL Specular Reflectance Standard
Ocean Insight offers specular reflectance standards for measuring shiny surfaces such as machined metals and semiconductor materials and low-reflectivity surfaces such as anti-reflective coatings and thin film coatings.
For measuring surfaces with low specular reflectivity, we recommend the STAN-SSL, which has ~4% reflectivity from 200-2500 nm. Add a STAN-HOLDER to keep your standards in place and to protect their coatings.
- Specular reflectance – low specular reflectivity (4% reflectivity from 200-2500 nm)
