Photolithography
Reynard Corporation offers custom patterned 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.
Thin film patterns 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.
