Product Description In applications that require large acceptance angles, such as light gathering for illumination, spherical lenses are unsuitable due to spherical aberration, or the effect of refractive power of a spherical surface becoming greater with increasing aperture. Aspheric lenses maintain constant focal length or very high NA, avoiding the need for multiple elements to correct spherical aberration. This simplifies system design by reducing weight and component count. It also results in less transmission loss, and less ghosting due to having fewer surfaces. The primary drawback of aspheric lenses is off-axis performance is poor. This is not a problem for coupling to and from optical fibers or collimating light sources, but aspheric lenses are not usable over a wide field of view.specification:Materialoptical glassDesign Wavelength632.8 nmSurface Figureλ/2Diameter Tolerance+0.1, -0.1 mmThickness Tolerance±0.2 mmParaxial Focal Length±2%Centration<3 arc minutesClear Aperture>85%Surface Quality60-40 scratch and digProtective Bevel0.25 mm x 45°Other ItemsFactory informationYutai Optics, we specialize in the design and volume manufacturing of high performance optical components such as lens,prisms, windows,filters,mirrors and more for use in optical instruments and laser systems, as well as for telecommunications,medical, environment monitoring industry,material is widely ranged from optical glass to IR and UV glass.
