This is a 10Z20BD.2 broadband dielectric mirror, manufactured by MKS/Newport, with a diameter of 25.4 mm and a thickness of 6 mm. The mirror is designed for use in the near-infrared (NIR) spectrum, specifically at a wavelength of 800 nm.
The mirror is made of Zerodur, a high-quality glass-ceramic material produced by Schott AG, known for its excellent thermal stability and low thermal expansion coefficient. This makes the mirror suitable for applications that require high precision and stability over a wide temperature range.
The mirror's coating is a New BD.2 AOI 0 on the front side, which is specifically designed for broadband applications. This coating ensures high reflectivity across the specified wavelength range, making the mirror ideal for use in a variety of optical systems.
The mirror's geometry is that of a thin lens, which is often used in optical systems to reduce weight and complexity. This particular mirror is currently in stock and available for immediate purchase. For more information, you can refer to the vendor's website through the provided weblink.
