Negative Meniscus Lens, N-BK7, AR Coating: 400 nm-700 nm, Unmounted — Model MP10619-A

Operating wavelength 400 nm-700 nm, focal length -300.0 mm, Ø25.4 mm, substrate N-BK7.

Product Description

Optical Material: N-BK7;
Operating Wavelength: 400 nm-700 nm (AR Coating);
Application: imaging, beam expander or reducer, convergence;

The negative meniscus lens from LBTEK consists of two surfaces with similar radii of curvature (the concave surface having a smaller radius than the convex surface), resulting in a negative focal length. Typically used for beam expansion/reduction, focal length extension, or numerical aperture reduction, this lens minimizes spherical aberration when the convex surface faces incident light during beam expansion/collimation or divergent light applications, while the concave surface should face incident light for converging beam collimation. Both surfaces are coated with 400-700 nm AR coatings to reduce surface reflectivity. While N-BK7 is the most common lens material for visible light and near-infrared applications, LBTEK manufactures these lenses using both N-SF11 and N-BK7 materials for diverse optical requirements. All lenses undergo precision machining and strict quality control, ensuring LBTEK delivers high-quality optical products at competitive prices.
