1λ first surface mirrors provide optical quality at an affordable price. Optimized for any angle of reflection and delivers exceptionally high reflectance in the visible spectrum. Choose from 1mm, 2mm, 3mm, and 6mm thicknesses.
λ/4 flatness mirrors are coated on a polished substrate for higher accuracy. Polishing the glass increases the surface flatness substantially, which is noticeable at magnifications of over 15x.
λ/8 is superior for equipment using a high magnification. Glass is ground down using an increasingly fine grain until it is nearly perfectly smooth. The polished substrate is then coated with enhanced aluminum, a dielectric overcoat, and tested with an interferometer to ensure a superior flatness compared to the λ/4 mirrors.
UV Enhanced FSM offers superior reflection for 10-400nm light. Standard aluminum has a poor reflection in this particular range, so our UV enhanced mirrors are popular for projects utilizing the ultraviolet spectrum.
Our engineers are standing by to answer any questions you have about selecting the optimal mirror for your project.
