L-PCC081 38 mm Dia. Plano-Concave Lens; EFL=-500mm Uncoated
The L-PCC081 is a 38 mm diameter Plano-Concave lens, part of the extensive catalog offered by Ross Optical. This lens is designed with a negative focal length (EFL) of -500mm, making it suitable for applications that require light convergence or image reduction.
The lens is spherical in shape, with a concave surface that has a radius of curvature (R1) of -258.4mm. The center thickness of the lens is 2mm, providing a balance between optical performance and mechanical robustness. The lens is uncoated, which means it does not have any anti-reflective or protective coatings. This may result in higher reflectivity and susceptibility to environmental factors, but it also keeps the lens's cost down.
The lens is made of N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and wide transparency range. The glass has a refractive index of approximately 1.5168 at the specified wavelength of 587.6nm.
This lens is available from Ross Optical's website, and the link provided indicates that it is currently in stock. Given its specifications, the L-PCC081 could be a suitable choice for applications in fields such as imaging, metrology, beam shaping, and optical testing.
