L-PCC057 25 mm Dia. Plano-Concave Lens; EFL=-200mm Uncoated
The L-PCC057 is a 25 mm diameter Plano-Concave lens, part of Ross Optical's extensive catalog of optical elements. This lens is designed with a negative focal length (EFL) of -200mm, making it suitable for applications that require light convergence or divergence.
The lens's geometry is characterized by its base shape, which is circular, and a center thickness of 1.5mm. The inner and outer radii are both zero, indicating a plano surface on one side and a concave surface on the other. The concave surface has a radius of curvature (R1) of -103.36mm.
The L-PCC057 is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, uncoated lenses can be more susceptible to surface damage and may not perform optimally in certain lighting conditions.
This lens is designed to work with a wavelength of 587.6nm, which is in the visible light spectrum. It is spherical in shape, a common choice for its simplicity and cost-effectiveness.
