This product is a Plano-Concave Spherical Lens, offered by CVI Laser Optics. It is a high-quality lens, designed for use in laser applications, and is fabricated from N-BK7 Schott glass, a material well-known for its excellent optical properties. The lens has a diameter of 25.4 mm and a center thickness of 3.9 mm.
The lens's primary curvature is concave, with a radius of 309.1 mm. This, combined with its negative focal length of -600 mm, makes it suitable for use in applications where a diverging beam is required. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this also means it is more cost-effective and suitable for applications where such coatings are not necessary.
