20Z20ER.2 50.8 mm Dia. Zerodur Broadband Metallic Mirror; t=12.7mm Protected Silver 480-20000nm

This is a 20Z20ER.2 metallic mirror, boasting a broadband coating suitable for a wide range of wavelengths, from 480nm to 20000nm. The mirror, sourced from the reputable vendor MKS/Newport, is a circular-shaped component with a diameter of 50.8mm and a thickness of 12.7mm.

The mirror's base material is Zerodur, a high-quality glass-ceramic material manufactured by Schott AG, known for its excellent thermal stability and low thermal expansion coefficient. This makes the mirror an ideal choice for applications requiring high precision and stability over a wide temperature range.

The mirror's coating is a new ER.2 coating, which is a protected silver coating. This type of coating is known for its high reflectivity and durability, making it suitable for various optical applications. The coating is applied to the front surface of the mirror.

The mirror is classified as a thin lens due to its thickness relative to its diameter. This classification suggests that the mirror is designed to minimize optical aberrations, contributing to its high-performance capabilities.
