Polychromatic Objectives for UV, VIS and IR

Polychromatic Objectives for UV, VIS and IR

The lenses are completely made of synthetic fused silica. This makes them particularly suited for the focusing of high-power laser beams. The field of view is comparatively large. For this reason it is possible to employ them in monochromatic imaging applications. The microscopic object fields can be chosen up to about 1/3 of the focal length without much degradation of image quality if the apertures are reduced to f:3.

These objectives are not achromatic and require refocusing for each wavelength according to the data of the table. However the optical design provides good performance at all wavelengths from below 200 nm up to over 1000 nm. They are diffraction limited at wavelengths above 200 nm (OML 8.3.05) resp. 240 nm (OML 8.3.10).

The lenses are delivery without antireflection coating.
