L-BCC095 40 mm Dia. Double-Concave Lens; EFL=-200mm Uncoated
The L-BCC095 is a 40 mm diameter Double-Concave Spherical Lens, featuring an effective focal length (EFL) of -200mm. This lens is sourced from Ross Optical, a reputable vendor in the optical industry. The lens's double-concave design, characterized by its base shape being circular, contributes to its unique optical properties.
The lens's geometry includes a thickness edge of 4.1mm and a thickness center of 2.2mm, providing a balanced structure. The inner and outer radii are both zero, indicating a symmetrical curvature. The radii of curvature, r1 and r2, are -207.4161263mm and 207.4161263mm respectively, further emphasizing the lens's concave nature.
The L-BCC095 is made from N-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. The wavelength specified for this lens is 587.6nm. The lens does not come with any coating, as indicated in the item data.
This lens is a great option for applications that require a strong converging lens, such as in imaging systems, beam shaping, or other optical manipulations. Please note that the lack of coating may affect the lens's performance in certain applications, particularly those involving high-intensity light sources or specific wavelength ranges. Always ensure to consider all factors when selecting optical components for your application.
