L-PCC075 38 mm Dia. Plano-Concave Lens; EFL=-75mm Uncoated
The L-PCC075 is a 38 mm diameter Plano-Concave lens, part of the extensive catalog of optical elements offered by Ross Optical. This lens is designed with a negative focal length (EFL) of -75mm, making it suitable for applications that require light convergence or image reduction.
The lens is spherical in shape, featuring a concave surface with a radius of curvature (R1) of -38.76mm. The inner and outer radii are both zero, indicating a uniform curvature across the lens surface. The center thickness of the lens is 2mm, providing a balance between optical performance and structural integrity.
The lens is made from N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high Abbe number. This makes the lens suitable for use across a wide range of wavelengths, particularly in the visible spectrum.
The lens is uncoated, meaning it does not have any anti-reflective or protective coatings. While this may result in higher reflective losses and increased susceptibility to environmental damage, it can also simplify the design and manufacturing process, reducing costs and lead times.
