Enhanced aluminum and dielectric mirror sheets are carried in stock in various thicknesses and types. Material is typically fabricated according to customer specifications. More durable, high-efficiency dichroic reflectors (sometimes referred to as dichroic beamsplitters) are also available to reflect desired wavelengths while passing other light. MidOpt stocks visible-near IR, red, green, blue, near-infrared (hot mirror) and visible (cold mirror) reflectors which are sized to specified requirements. In addition to flat sheet materials, the above can be supplied in right angle (prism), concave, convex and many other configurations.
