Aspheric Lenses

Unlike spherical lenses, aspheric lenses have a constant radius of curvature. The radius of curvature of aspheric lenses changes continuously from the middle to the edge with the change of the main optical axis, which can better correct spherical aberration and chromatic aberration, and then Improve the spot quality of the lens. By adjusting the conic constant and aspheric coefficient, the lens is optimized to minimize aberrations, and it is often used in barcode scanning, laser alignment, optical imaging and other fields. Aspheric lenses use a single-element design to help minimize the number of lenses in an optical system. Aspheric lenses allow optical component designers to correct aberrations using a smaller number of optical elements than traditional spherical elements because the former is They provide more aberration correction than the latter can provide using multiple surfaces.
Bohr optics offers uncoated and AR coated aspherical lenses. AR coating options include UVA, VIS, NIR, SWIR, IR1, IR2. Bohr optics provides aspherical lenses of various materials. Among them, zinc selenide material is suitable for infrared band applications, molded optical glass is suitable for cost-effective mass production, and TPX material is suitable for terahertz band applications.
