20Z40BD.1 50.8 mm Dia. Zerodur Broadband Dielectric Mirror; t=12.7mm 488-694nm

This is a 20Z40BD.1 broadband dielectric mirror by MKS/Newport, designed with a circular base shape and a diameter of 50.8 mm. The mirror has a thickness of 12.7 mm and is made of Zerodur by Schott, a material known for its excellent thermal stability and homogeneity.

The mirror is specifically coated for use at a wavelength of 588 nm, with a front coating of "new bd.1 aoi 0". This coating ensures high reflectivity and durability, making it suitable for various applications within the specified wavelength range of 488-694 nm.

The mirror's geometry is that of a thin lens, which contributes to its broadband performance and low sensitivity to angle of incidence. This makes it an ideal choice for applications requiring wideband reflection and high damage threshold.
