Product Name: Diffuse Reflectance Standards
Product Description
WS-1 Diffuse Reflection Standard
The WS-1 Diffuse Reflectance Standard is made of PTFE, a diffuse white
plastic that provides a Lambertian reference surface for reflectance
experiments. The WS-1 comes in an anodized aluminum housing, and is hydrophobic,
chemically inert and very stable, even in deep-ultraviolet applications. It is
>98% reflective from 250-1500 nm and >95% reflective from 250-2200 nm.
The reflective area of the WS-1 has a 32 mm OD. The diffusing material is
encased in a small receptacle with screw-on top. The material is almost
uniformly reflective (>95%) by wavelength across the entire range of 250-2000
nm.
WS-1: $299.
WS-1-SL White Reflection Standard with Spectralon
The WS-1-SL is a diffuse reflectance standard from Labsphere and is made from
their patented diffuse reflectance material, Spectralon. Spectralon is
hydrophobic and is thermally stable to 350 °C. The durable material provides
highly accurate, reproducible data. Unlike all the other PTFE-based standards on
this page, the WS-1-SL often can be smoothed, flattened and cleaned if nicked or
soiled.
WS-1-SL: $329
WS-1-SS White Standard with Stainless-steel Housing
The WS-1-SS comes in a stainless steel housing and has the same properties as
the WS-1. In addition, the surface of the WS-1-SS is slightly recessed to allow
the RPH-1 Reflection Probe Holder to sit on the standard without coming in
direct contact with the standard’s surface. WS-1-SS: $364
WS-1-SS: $408
WS-1-GEM White Standard
Conceived for use in colorimetric applications involving diamonds and other
gems, the WS-3-GEM White Reference Tile consists of a diffuse PTFE-based
material, shaped to form a holder within its stainless steel receptacle. Because
of its concave shape, the WS-3-GEM becomes an integrating sphere when
illuminated.
The WS-3-GEM has >98% reflectivity from 400-1500 nm and >95% reflectivity from
250-2000 nm. Like the WS-1, the WS-3-GEM's reflectance material is hydrophobic,
chemically inert and very stable, even in deep-UV applications.
WS-3-GEM: $546
