STAN-SSH Specular Reflectance Standard

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

STAN-SSH-NIST 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

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)
• Convenient holder – optional accessory holds standard in place

WS-1 Diffuse Reflectance Standard

The WS-1 uses a PTFE optical diffuser, a Lambertian material distinguished by its white matte finish and reflectivity >98% from 250-1500 nm and >95% from 250-2200 nm.

• Diffusing materials – choose from PTFE (WS-1) or Spectralon (WS-1-SL) standards
• High reflectivity over broad range – >95% reflectivity from 250-2200 nm
• More options – additional Spectralon reflectance standards and targets also available
