Ocean Optics 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.
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 – options for high and low specular reflectivity
- Calibrated standard – NIST-traceable version available
- Convenient holder – optional accessory holds standard in place
