Reflective optics do not experience chromatic effects associated with refractive optics, where refractive index varies with wavelength. Consequently reflective objectives can have excellent optical performance across an extremely broad wavelength range limited only by mirror reflectance. The reflective surfaces are broadband coated with aluminum or gold and over coated with magnesium fluoride (MgF 2) are usable from 200 nm to 20 µm. Special gold coatings for the visible to IR region are available upon request.

The natural wonders of Graskop are probably the most photographed and painted scenes in the world. Situated in the magnificent Mpumalanga Province, Graskop is ideally located in the heart of the tourism region and is the gateway to the Panorama Route.

Average reflection per surface of each mirror is 85% in the UV-VIS, and 90% in the IR (with a dip to 76% near 820nm).

Our reflective microscope objectives are fabricated from a single material providing a uniform thermal coefficient of expansion. Each objective contains two highly polished nickel spherical mirrors coated with aluminum and magnesium fluoride. The primary mirror has a spherical concave surface with a center hole. The secondary mirror is a small convex spherical mirror that is machined into the spider assembly. The objectives are hand assembled in interferometric alignment fixtures allowing each pair of mirrors to be optimized as a set to achieve maximum resolution.

Spot sizes of 2 µm for the 15X objective and 1 µm for the 36X objective are typical.
