G313210400 10 mm Dia. N-BK7 Double-Concave Lens; EFL=-10mm

The G313210400 is a high-quality double-concave lens, boasting a 10 mm diameter and a center thickness of 1mm. This lens is fabricated from N-BK7, a popular borosilicate glass known for its excellent optical properties, making it an ideal choice for various applications. The lens features a negative focal length (EFL) of -10mm, indicating its concave nature, which causes parallel rays to converge before the focal point.

The lens's geometry includes radii of curvature of -10.669mm and 10.669mm for the first and second surfaces, respectively. The inner and outer radii are both zero, suggesting a symmetrical design. The lens's shape is spherical, ensuring consistent optical performance across the entire surface.

This lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, enhancing its overall performance and durability. The coating is designed to reduce reflection and increase transmission, making the lens suitable for use in high-precision optical systems.
