OPTICAL FLATS

High performance windows, mirrors and wedges in a wide variety of shapes, sizes, and materials.  Our technicians are comfortable dealing with 100+ optical glasses, fused silica, and crystalline substrate materials. Selecting the optimal process technology and adhesion/blocking method allows us to quickly and efficiently produce optical flats to the most demanding specs.

OPTICAL FLATS
SGOPTICS delivers high performance windows, mirrors and wedges in a wide variety of shapes, sizes and materials. We are accustomed to dealing with most all optical glasses (100+), fused silica and crystalline substrate materials such as CaF2, Ge, MgF2, Si, ZnSe, ZnS and Amtir. Our technicians are able to produce optical flats to the most demanding specs for flatness, transmitted wavefront, parallelism (angular tolerances on wedges) and surface cosmetics.

Whether using continuous polishers or double-side polishers, we confidently select the optimal process technology, and adhesion and blocking method (pitch, tape/wax or optical contacting) to meet your specs. Our polishing technicians clearly understand that substrate type, dimensions, blocking method and material, final shaping, aspect ratio and coating, all significantly impact the end result. For wedged optics we have an extensive inventory of tooling, in many cases allowing us to avoid tooling charges and to reduce delivery times to our customers.

Coatings range from the deep ultraviolet through the mid-wave infrared. We provide dielectric and metallic mirrors; likewise notch, edge, dichroic, color substrate and neutral density filters.
