The 12-623 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-266nm-0-45-ndyag-laser-line-mirror/41457/.
The mirror is crafted from fused silica (mal-1965) and features a dielectric coating on the front surface, specifically the EDM LM 266 38-829 coating. This coating is designed to optimize performance at a wavelength of 266nm, making it suitable for a range of applications involving Nd:YAG lasers.
The 12-623 mirror is shaped as a thin lens, with a circular geometry. This shape, combined with its 4mm diameter, makes it a versatile option for various optical setups. Please note that the mirror's coating is applied only to the front surface, as indicated in the item data.
