Janos A2010-283 1″ Gold Pyrex Mirror

Janos A2010-283 1″ Gold Pyrex Mirror sounds like a small precision optical mirror made by Janos Technology, LLC, featuring:

• 1-inch diameter — the “1″” in the designation refers to a 1-inch (~25.4 mm) clear aperture mirror.

• Pyrex substrate — Pyrex (borosilicate glass) is commonly used for optical mirrors due to its low thermal expansion and good polishability.

• Gold reflective coating — gold coatings are used for high reflectivity in the infrared region (especially from ~0.8 μm up into the mid/far IR). They are also very durable and resistant to environmental degradation.
