A UV Grade Fused Silica Mirror is a mirror made of fused silica that is designed to reflect ultraviolet light.

The reflecting surface of the mirror is usually a thin coating of aluminum or silver.

A first surface mirror is a mirror where the coating is on the front surface, thereby eliminating the optical properties of the glass from affecting the incident or reflected light.

The dimensional tolerance of the mirror is +0.0/-0.1mm for both standard and high grade.

The surface quality of the mirror is scratch/dig 40/20 for standard grade and 10/5 for high grade.
