Precision Mirrors

These superpolished substrates result in low scattering losses and significantly fewer defects. We provide custom high-reflectivity mirrors that offer superior performance and value to customers developing laser cavities, ranging from small and lightweight range finding lasers to industrial lasers.

We design and manufacture our precision mirrors in both the United States and the United Kingdom.

Eliminating Defects

The smallest defect on an optical surface often leads to system failure. Our goal is to minimize or eliminate system failures by offering the highest quality polishing and coating for our precision optical mirrors.

Precision mirrors are fabricated in a number of shapes and sizes, including aspheric and off-axis. Conventional optical grade flats or shaped substrates are precision polished and inspected at magnification and using white light interferometry to ensure there are no underlying defects before coatings. Careful cleaning and coating processes ensure microscopic particles are not encapsulated into the coating.

• Super polisher for parts up to 18"
• Glass mills for complex precision shapes
• Magnetorheological finishing (MRF)
• IBS and IAD coating capabilities

Durable and Dependable

Dielectric laser cavity and beam routing mirrors demonstrate very high reflectivity and high laser damage threshold.

Protected and enhanced metal reflector coatings offer superior abrasion and climatic resistance for lower power applications.

Applications

• Laser cavities, e.g. ring laser gyros
• Direct energy weapons
• Missiles
• Satellites and airplanes
• Medical devices, including consumables

Coatings

From high transmission broadband anti-reflection coatings to V-coats for high energy applications, our extensive coating capabilities for precision optical components deliver performance across the spectrum from the UV to the FIR.

• Metallic
• Broadband dielectric
• Ultra low loss dielectric

Metrology

We have made a significant investment in metrology equipment to ensure that our customers receive quality, high-performing precision optical components.

• Cavity ring down spectrometer (CRDS)
• Interferometers ranging 4" - 18"
• White light interferometers Atomic force microscopes

Environmental Testing

Environmental testing of components and coatings is critical for the assurance of performance in rugged conditions. G&H environmental testing capabilities include MIL-C-675C, MIL-C-48497A, MIL-E-12397, and MIL-M-13508C for endurance against abrasion, adhesion, humidity, temperature, and environmental conditions.
