Photolithography
Reynard Corporation offers custom patterned thin film optical coatings to produce a wide range of complex optics with geometries on substrates up to 18 inches in diameter using our highly accurate photolithography process.
A thin film patterned optic can be applied to any vacuum compatible optical substrate material, including optical glass, certain plastics, and ceramics to produce a variety of shapes to meet your custom optical coating requirements.
• Pattern Geometries Down to 5µm
• Multiple Pattern Stacking
• Gapless Patterns – no physical space between adjacent coatings
• Custom Patterns
• Front Surface to Back Surface Pattern Alignment to ≤ 25mm
All optical elements are thin film designed, manufactured, and tested in-house.
ISO 9001:2015 certified and ITAR registered.
