The 87-384 is a 40mm diameter dielectric mirror, specifically designed for broadband usage within the 750-1100nm wavelength range. This mirror is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The mirror's geometry is circular, with a thickness of 5mm, and it is made from fused silica, as indicated by the Material ID. The coating on the front surface is EDM DCURV750TO11000, which is specifically designed for broadband applications within the specified wavelength range.
The mirror is designed in the shape of a thin lens, which is a type of lens where the thickness of the lens is significantly less than the diameter of the lens. This design is often used in optical systems where weight and space are at a premium.
