L-PCC004 20 mm Dia. Plano-Concave Lens; EFL=-30mm Uncoated
The L-PCC004 is a 20 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 -30mm, making it suitable for applications that require light convergence.
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 (R1) of -15.504mm.
The L-PCC004 is made from the material n-bk7 schott, a popular choice for optical elements due to its excellent optical properties. The wavelength for this lens is 587.6nm.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflection, increasing transmission, or providing protection against environmental factors. However, the L-PCC004, in its uncoated form, offers a more cost-effective solution for applications where such enhancements are not required.
The lens is currently in stock and more information can be found on the Ross Optical website.
