BK7 Grade A Optical Glass Standard MB11-025 Circular Mirror
Description
Mirrors have a highly polished surface for reflecting light. The reflecting surface is usually a thin coating of aluminum or silver. Most mirrors for optical applications are called first surface types since the coating is on the front surface thereby eliminating the optical properties of the glass from affecting the incident or reflected light. The rear surface is usually fine ground.
All of the following mirrors have a protected Aluminum coating applied to the front surface.
