Fused Silica Secondary Mirror


We make our own fused silica secondary mirrors.

Let us make one CUSTOM for you if stock isn’t what you need.

We start with raw 1/4″ thick fused silica and precisely edge

a perfect 45 degree ellipse. Then we grind and polish, test and coat.

What you have is a perfectly edged mirror with smooth sides and pristine coated surface.

We then coat the mirror with protected aluminum for maximum reflectance and durability
