L-BCC059 25 mm Dia. Double-Concave Lens; EFL=-250mm Uncoated
The L-BCC059 is a 25 mm diameter double-concave lens, part of the extensive catalog offered by Ross Optical. This lens boasts an effective focal length (EFL) of -250mm, making it suitable for applications requiring strong negative magnification.
The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes a thickness edge of 2.1mm and a thickness center of 1.5mm, providing a robust structure. The inner and outer radii are both zero, indicating a symmetrical curvature.
The L-BCC059 is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material is ideal for applications that require high image quality and minimal chromatic aberration.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, uncoated lenses can be advantageous in certain applications due to their lower cost and simpler manufacturing process.
