L-PCC090 38.1 mm Dia. Plano-Concave Lens; EFL=-200mm Uncoated
The L-PCC090 is a 38.1 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 -200mm, making it suitable for applications that require light convergence or divergence.
The lens is spherical in shape, with a base shape of circular. The geometry includes a center thickness of 2.5mm, an inner radius of 0mm, and an outer radius of 0mm. The lack of curvature on one side (plano) and the concave curvature on the other side contribute to its diverging properties.
The lens is made from n-bk7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The wavelength for this lens is 587.6nm, which falls within the visible light spectrum.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing protection against environmental factors. However, this lens is designed to function without these enhancements, making it a cost-effective option for applications where coating is not necessary.
The lens is currently in stock and more information can be found on the Ross Optical website.
