On this page, we provide pricing, specifications, and advice on how to use them for scientific and engineering applications.

Applications include use in flight simulators, barcode scanners, and factory automation. First surface mirrors also function as bounce mirrors for binocular mounts, projecting video onto the floor or ceiling, and Hollywood special effects.

The enhanced aluminum mirror coating allows for a high reflection over a large wavelength range. See the wavechart for more detail.

A first surface mirror, also known as front surface mirror, has a high reflectance coating on the face of the glass that provides a true reflection with no double image. A dielectric overcoat further enhances reflection of visible light while providing durability and full protection from oxidation. Optical grade first surface mirrors are manufactured under strict quality control, ensuring a defect free surface and enhanced flatness.

A blue Nitto laminate is applied over the finished mirror to protect it during cutting, shipping, and until final use. We’re flexible in terms of whether it’s boxed or crated depending on the size of your order and your preference. Small mirrors are carefully wrapped in protective materials and shipped in a box, and larger mirrors are packed in foam, crated, and shipped via freight. All shipments are fully insured to protect your order.

Strehl ratio is an important performance measure for adaptive-optics systems. Its calculation is more complicated than that of variances. Nevertheless, it is shown below that one can obtain exact expressions for the Strehl ratio for propagation through uncorrected turbulence, and through turbulence for which all modes except tilt have been corrected. Asymptotic expressions are also obtained that apply when the distortion is high.

A first surface mirror, also known as front surface mirror, has a high reflectance coating on the face of the glass that provides a true reflection with no double image. A dielectric overcoat further enhances reflection of visible light while providing durability and full protection from oxidation.

Using multi-layer coating technology in a vacuum chamber, aluminum is deposited onto ultra-flat glass. A dielectric protective layer is simultaneously deposited to further enhance the reflective properties. The dielectric layer provides a durable overcoat that protects it from oxidation and enhances durability. In addition, the dielectric coating enhances reflection in the visible spectrum and a wider angle of incidence. Using clean glass and strict manufacturing process is essential to preventing dust from creating bubbles in the coating, and other potential anomalies in the coating, such as thermal expansion and fingerprints.
