LP11-38-200 38 mm Dia. N-BK7 Plano-Concave Lens; EFL=-200mm Uncoated
This is the LP11-38-200, a 38 mm diameter Plano-Concave Spherical Lens, sourced from CeNing Optics. The lens is made of N-BK7, a popular optical glass, and features a negative focal length (EFL) of -200mm, making it suitable for applications that require light convergence.
The lens has a center thickness of 2mm and a concave surface with a radius of curvature (R1) of -103.75mm. The inner and outer radii are both zero, indicating a uniform curvature across the lens surface. The wavelength for this lens is 546.1nm, which is within the visible light spectrum.
Notably, this lens does not come with any coating, as indicated in the item data. Coatings are often applied to lenses to enhance their performance by reducing reflection, increasing transmission, or providing protection against environmental factors. However, this uncoated lens may be suitable for applications where such enhancements are not necessary or desirable.
