39-910 25mm Dia. Protected Silver Coated; ZERODUR Mirror Protected Silver 450-10000nm

The 39-910 is a 25mm diameter metallic mirror, specifically a protected silver mirror, sourced from Edmund Optics. This mirror is designed for use within a broad wavelength range, from 450nm to 10000nm, making it a versatile choice for various optical applications.

The mirror's base shape is circular, and it has a thickness of 4mm, providing a sturdy and robust structure. The material of the mirror is ZERODUR, a low-thermal expansion glass-ceramic from Schott, which is known for its excellent dimensional stability and homogeneity, making it an ideal choice for high-precision optical systems.

The mirror's coating is a front-side protected silver coating, denoted as 'edm dprotsil3001000'. Protected silver coatings offer a good balance between cost and performance, providing high reflectivity across a wide range of wavelengths. The protection layer ensures the longevity of the coating, protecting it from tarnishing and oxidation, thereby enhancing the mirror's durability.

The mirror is classified as a 'Thin Lens', indicating its suitability for use in optical systems where minimal thickness and weight are desirable. The mirror's specifications, including its material, coating, and geometry, make it a reliable and efficient component for various optical applications.
