LBTEK Precision Polished Aspheric Lens with Mount, N-BK7 or equivalent materials, AR Coating: 400 nm-700 nm, currently available in three sizes: Ø12.7 mm, Ø25.4 mm, Ø50.8 mm. The spherical refraction of ordinary lenses cannot converge parallel light to a single point, resulting in spherical aberration. In contrast, the curvature of an aspheric lens changes continuously from the center to the edge. By adjusting the conic constant and aspheric coefficients, spherical aberration can be minimized, allowing light to converge to a single point and thereby improving optical performance. LBTEK precision polished aspheric lenses are pre-mounted in standard lens barrels, with the product model, type, diameter, focal length, and numerical aperture engraved on the barrel surface for easy identification of lens parameters.
