Frequently Asked Questions
A fused silica aspherical lens is a lens that has a different radius of curvature from the surface center to edge, which can eliminate spherical aberrations and promote spotlight accuracy rate.
Aspherical lenses can eliminate spherical aberrations as well as the error which other spherical lenses can not eliminate. They can also replace multiple lenses system, thereby reducing weight, size, and cost.
Fused silica aspherical lenses are suitable for photographic camera lens and viewfinder, television camera tube, zoom camera lens, satellite infrared telescope, and video camera lens.
An aspherical lens has a simple construction, which allows it to replace multiple lenses system, thereby reducing weight, size, and cost.
