L-BCC050 25 mm Dia. Double-Concave Lens; EFL=-30mm Uncoated
The L-BCC050 is a 25 mm diameter Double-Concave Spherical Lens, featuring a negative focal length (EFL) of -30mm. This lens is sourced from Ross Optical, a reputable vendor in the optical industry. The lens's concave-concave base shape is circular, contributing to its wide range of applications.
The lens's geometry includes a thickness edge of 6.7mm and a center thickness of 1.5mm, providing a robust structure while maintaining a sleek profile. The inner and outer radii are both zero, indicating a symmetrical curvature. The radii of curvature, R1 and R2, are -32.11022289mm and 32.11022289mm respectively, contributing to the lens's double-concave nature.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It is designed to work with a wavelength of 587.6nm, making it suitable for various applications in the visible light spectrum.
Notably, this lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. While this may result in higher reflectivity, it also means the lens is more cost-effective and suitable for applications where such coatings are not necessary.
