Frequently Asked Questions

The mirrors are used 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 thickness tolerance is ± 0.2 mm for both standard and high-grade mirrors.

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