051-5306-i0 12.7 mm Dia. N-BK7 Dual Band Laser Mirror; t=3mm Dielectric 532/1064nm

This is a high-quality dielectric mirror from EKSMA Optics, designed for dual-band laser applications. The mirror has a circular shape with a diameter of 12.7 mm and a thickness of 3 mm at the edge, making it suitable for a wide range of optical systems.

The mirror is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. This material is widely used in laser applications due to its low absorption and high transmission in the visible and near-infrared regions.

The mirror's coating is a crucial component, designed to reflect light at specific wavelengths. In this case, the coating is optimized for 532 nm and 1064 nm, making it ideal for Nd:YAG lasers, which often operate at these wavelengths. The coating is applied to the front surface of the mirror, ensuring high reflectivity and durability.

The mirror's shape is defined as a thin lens, which suggests that it may have some focusing or collimating properties. However, the specific curvature and optical power of the lens are not provided in the item data.
