12-625 4mm Dia. 355nm 0-45°; Nd:YAG Laser Line Mirror Dielectric

The 12-625 is a dielectric mirror designed for use with Nd:YAG lasers, offering a 4mm diameter and a thickness of 3mm. This mirror is sourced from Edmund Optics and is currently in stock, with further information available at https://www.edmundoptics.com/p/4mm-dia-355nm-0-45-ndyag-laser-line-mirror/41459/.

The mirror is designed to reflect light at a wavelength of 355nm, a common wavelength for Nd:YAG lasers. The dielectric coating on the front surface of the mirror ensures high reflectivity for this wavelength, making it ideal for laser applications.

The mirror's geometry is that of a thin lens, with a circular base shape and a diameter of 4mm. The thickness of 3mm is consistent with the requirements for a thin lens, providing the necessary rigidity while minimizing optical distortion.

The material used for this mirror is fused silica, identified as fused sil mal-1965 in the item data. This material is known for its high transparency and resistance to thermal shock, making it suitable for use in laser applications.
