Clear Patterns, Reticles, Apertures on High Power Dielectric Laser Reflector Coatings
For applications requiring transparency and/or power resistence greater than achievable with opaque (metallic, etc.) surfaces this process creates patterns on dichroic reflectors with selective transparency.

 

Wavelength:	Per standard high power dielectric coating, visible, near visible
Reflectivity:	20% to 98%, based on requirement
Incidence:	0° - 90°, per specification
Power resistance:	2-8 megawatts/mm2, pulsed
Pattern definition:	<1µm (semiconductor pattern quality)
Material:	Glass, fused silica, etc.
Dimensions:	Up to 6 inch (152.4mm) thickness, 0.04 inch - 0.09 inch (1.016mm -2.286mm)
Pattern generation:	Per customer or National Aperture, Inc. via AutoCad™
Pricing:	Per quote
