Precision asphere ii-vi
WebOct 1, 2006 · The asphere measurement is the difference between the design asphere surface and the actual surface-the same result expected from standard laser Fizeau interferometry. The result is an interferometric, high-data-density x, y, and h map with form, waviness, and defect detection in one noncontact measurement (see Fig. 2). WebWith the uniting of SUMITA’s mold production technology and glass materials development technology makes it possible to manufacture precision molding aspheric lenses. Aspheric lenses by precision molding are used in digital cameras, pickup lenses, and in the field of optical communications. Available lens diameter: 1.0 mm – more than 30 mm.
