Aspherical lens Aspherical lens is a single optical component with one or two aspheric surfaces. An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. As optical systems are pushed to be better, faster, and cheaper, it becomes necessary to explore aspheric solutions. Aspherical elements eliminate monochromatic aberrations (e.g. spherical aberration) and improve focusing and collimating accuracy. The whole system will be smaller and lighter, and possibly cheaper than the multi-lens design.    Our aspheric lenses are made by grinding & polishing. So they are more precise than traditional mould pressed. And also the tooling cost for grinding & polishign would be cheap and small quantity order would be accept.   We can offer Precision Polished Aspheric Lenses Aspheric Condenser Lenses Aspheric Cylindrical lenses ect.   Specifacation of Aspherical Lens   Size range The focal length range Wavelength range High precision aspheric lens 10-50mm 7.5-50mm 0.4-1.6 UV fused quartz aspheric lens 10-50mm 8-60mm 0.2-2.2 Best form aspherical lens 25mm 25-100mm 0.532-1.064 Achromatic aspheric lens 9-25mm 12-50mm 0.4-0.7 Plastic aspheric lens 10-25.4mm 6.35-254mm 0.4-1.2 Small diameter aspheric lens 1.8-9.9mm 0.7-22mm 0.4-1.6 Small diameter infrared aspheric lens 3.5-6.5mm 1.5-4mm 2-14 Zinc selenide aspheric lens 25.4-50.8mm 12.7-50.8mm 0.6-16 Silicon aspheric lens 25-50mm 25-50mm 1.2-7 IG6 aspheric lens 25-50mm 12.5-50mm 0.9-13 Germanium aspheric lens 25mm 12.5-100mm 2-16 Aspheric cylindrical lens 25mm 20-50mm 0.4-1.6
