ASPHERICAL OPTICS

OpticsLand, a precision optics division of Del Mar Ventures, supply aspherical lenses and mirrors made of optical glass, fused silica, quartz, sitall, germanium, fluorite, optoceramics and other materials. Optical components with convex and concave surfaces are made within the parameters range as follows:

Kinds of Aspherical Surfaces

Component overall dimensions, (mm)

Steepness max, ( deg.)

Gradient of asphericity, (mm/mm)

Accuracy of shaping

 Curvature radii, (mm)

deviation of normals, (arcsec)
