L-BCC060 25 mm Dia. Double-Concave Lens; EFL=-300mm Uncoated
The L-BCC060 is a 25 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical vendor, Ross Optical. This lens boasts an effective focal length (EFL) of -300mm, making it suitable for applications that require strong negative magnification.
The lens's geometry is characterized by its concave-concave base shape, with a center thickness of 1.5mm and an edge thickness of 2.1mm. The inner and outer radii are both zero, indicating a symmetrical curvature. The lens is designed to work with a wavelength of 587.6nm, typical for visible light applications.
The L-BCC060 is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion. This material is widely used in various optical applications, including imaging systems, beam shaping, and laser applications.
Notably, this lens is uncoated. While coatings can enhance performance by reducing reflection, increasing transmission, or providing environmental protection, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
