L-PCC007 21 mm Dia. Plano-Concave Lens; EFL=-40mm Uncoated
The L-PCC007 is a 21 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 -40mm, making it suitable for applications that require light convergence or image reduction.
The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes a center thickness of 2mm, an inner radius of 0mm, and an outer radius of 0mm. The curvature of the lens is defined by a radius of 20.672mm (R1), which is the radius of the spherical surface that forms the concave shape of the lens.
The lens is made from the material n-bk7 schott, a common choice in optical applications due to its excellent optical properties. The wavelength for this lens is 587.6nm. It's important to note that the lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
