L-PCC105 50 mm Dia. Plano-Concave Lens; EFL=-75mm Uncoated
The L-PCC105 is a 50 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 -75mm, making it suitable for applications that require light convergence or divergence.
The lens is spherical in shape, featuring a concave surface with a radius of curvature (R1) of -38.76mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a symmetrical design. The lens has a center thickness of 2.5mm, providing a balance between optical performance and mechanical robustness.
The L-PCC105 is made from N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and wide transparency range. It is specifically designed for use at a wavelength of 587.6nm.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their optical performance by reducing reflection, increasing transmission, or providing other desirable properties. However, the absence of a coating in this case suggests that the lens is intended for use in applications where such enhancements are not required or desirable.
This lens is currently in stock and available for purchase through the Ross Optical website. For more information, please refer to the provided weblink.
