Anti Reflective Coatings

Anti-Reflective Coatings

 (4)
These anti-reflective optical coatings are designed to reduce reflectance and improve transmission for glass and plastic optics. Magnesium fluoride (MgF2) is a versatile and durable AR coating for glass substrates. AR520 is an AR coating designed specifically for plastic substrates.

Features
  • Anti-reflective Coatings suitable for both glass and plastic substrates
  • AR Coatings that can be deposited on substrates up to 90 inches
  • Magnesium fluoride meets durability specifications of Mil-C-675
  • AR520 is suitable for acrylic, polycarbonate and other plastics
Custom design services available.

Beam Splitters

Beam Splitters

 (4)
Dielectric beamsplitters on plate glass are stocked in common reflectance/transmission configurations. Also known as plate beam splitters or partial mirrors is an optical device which can split an incident light beam (e.g. a laser beam) into two or more beams, which may or may not have the same optical power. Beamsplitters are used for very different purposes. For example, beam splitters are required for interferometers, autocorrelators, cameras, projectors, teleprompters, simulators and laser systems. We stock coated beamsplitter sheets and cut them to meet specific customer requirements.

Neutral Density Filters

Neutral Density Filters

 (12)
Neutral density filters (NDF) are offered in fixed densities ranging from 0.1 to 4.0. NDF coatings are provided complete on float glass substrates or can be applied to other substrates provided by our customers.

We stock uncoated diameters in 1" and 2" sizes and offer fast turnaround on coated parts.
Please specify size and density requirements.
