L-BCC030 13 mm Dia. Double-Concave Lens; EFL=-30mm Uncoated

The L-BCC030 is a 13 mm diameter Double-Concave Spherical Lens, featuring a negative focal length (EFL) of -30mm. This lens is sourced from Ross Optical, a reputable vendor known for their high-quality optical components.

The lens's geometry is characterized by its concave-concave base shape, with a center thickness of 2mm and an edge thickness of 3.3mm. The inner and outer radii are both 0, indicating a symmetrical curvature. The radii of curvature for the first and second surfaces are -31.56034464mm and 31.56034464mm respectively, suggesting a high degree of curvature designed to refract light effectively.

The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. It is designed to work optimally at a wavelength of 587.6nm. The lens does not come with any coating, as indicated by the empty 'coating' field in the item data.

This lens is a great choice for applications that require a strong converging lens, such as in imaging systems, beam shaping, or light collimation. However, its uncoated surface may result in higher reflectivity and lower transmission compared to coated lenses. Therefore, it may not be ideal for applications that require high transmission or low reflectivity.
