Avian Technologies offers first surface specular standards with calibrations traceable to NIST/NRC. The mirrors are first surface aluminum with a magnesium fluoride overcoat that have been aged to enhance their long term stability. These standards come in a protective holder and are available in either 2" (50.8 mm) square or 1.25" (37 mm) diameter sizes. Calibrations are at near-normal (8°) geometry.

If you require measurements at non-near normal angles or at -s or -p polarization (or non-polarized light), we recommend two of our associates:
Optical Data Associates (Dr. Michael Jacobson), contact at or by phone at 1-800-494-7333.
Optical Reference Laboratory (Dr. Bill Sweet), contact at, or by phone at 530-753-4358.
We have worked with Mike and Bill for more than 20 years. They are truly experts in measurement of specular materials.
