Double Sided Polishing

JTI Double-sided Polishe
Janos Technology has some of the most advanced double sided grinding and polishing equipment in the industry. This state-of-the-art equipment is very economical for high volume window production. Savings can also be realized on lower quantities depending on material and window size. We will also have the capability to produce single surface mirrors back to back for even greater economy.

We are able to produce a variety of window shapes, circular, square, rectangle, octagonal, elliptical and irregular shapes in sizes up to 7.5 inches.

Surface flatness of 1/10 λ @ 0.6328µm and surface finishes of 20-10 scratch-dig are achievable depending on material and part size.

With our current equipment we are able to fabricate a variety of materials including:

Germanium (Ge)
Silicon (Si)
Zinc Selenide (ZnSe)
Barium Fluoride (BaF2)
Calcium Fluoride (CaF2)
Magnesium Fluoride (MgF2)
Fused Silica (FS)
