L-BCC055 25 mm Dia. Double-Concave Lens; EFL=-100mm Uncoated
The L-BCC055 is a 25 mm diameter Double-Concave Spherical Lens, featuring an Effective Focal Length (EFL) of -100mm. This lens is sourced from Ross Optical, a reputable vendor known for their high-quality optical components.
The lens's base shape is circular, with a thickness of 3.1mm at the edge and 1.5mm at the center. The inner and outer radii are both zero, indicating a symmetrical curvature. The radii of curvature for the first and second surfaces are -103.8854407mm and 103.8854407mm respectively, suggesting a strong converging effect on incoming light rays.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It is designed to operate at a wavelength of 587.6nm. The coating parameter is left empty, indicating that this lens is uncoated. While uncoated lenses can be more economical, they may exhibit higher reflectivity and lower durability compared to coated alternatives.
This lens is a Spherical type, which is the simplest and most common type of lens. It is suitable for a wide range of applications, including imaging systems, beam shaping, and laser applications. However, due to its negative focal length, it is particularly useful in applications where a diverging lens is required.
