This is a 042-0350-i0-45 25.4 mm Dia. UVFS Broadband Laser Mirror, a high-quality optical component sourced from EKSMA Optics. The mirror is designed with a circular base shape and a diameter of 25.4 mm, making it suitable for a wide range of optical applications.
The mirror's thickness at the edge is 6 mm, and it is made from UVFS material with the ID 1965. This specific mirror is coated with a front dielectric coating, EKS HRBB 343-355 45, which is specifically designed for broadband and laser line mirrors with an angle of incidence (AOI) from 0 to 45 degrees.
The mirror is designed to work with a wavelength of 355 nm, making it ideal for use in ultraviolet (UV) applications. The coating is a dielectric type, which is known for its high damage threshold, low scatter, and excellent spectral performance.
The mirror is shaped as a thin lens, which is beneficial for applications where weight and space are critical factors.
