Military Coatings on Galvo Mirrors- Durable high-reflection coatings for superior performance

Reynard Corporation, a leading global supplier of optical components and thin film coatings announces high precision coatings Galvanometer mirrors.

Galvo mirrors are used in various laser system applications such as scanners, bar code readers, sweeping remote sensors, marking systems, and laser light shows. A mirror is modulated on it centered axis, causing a static laser beam to scan in a one-dimensional orientation. Adding a second Galvo mirror allows for scanning in two dimensions. For example, the first scans in an X-orientation across a single line, while the second mirror allows for Y-orientation movement. With a synchronized X-Y controller, any continuous geometric shape can be realized.

Mirrors are manufactured using most any substrate, but are most commonly made from BK-7, fused silica or silicon. With our CNC machining capabilities, we can shape these Galvanometer mirror substrates to suit any application. The substrates are then coated with a highly reflective protected metal or multi-layer dielectric tuned for the required wavelength band and application.  Our Galvo mirror coatings can achieve reflectivity of greater than 99.9% and are able to withstand the most rigid durability requirements per military specifications - including Temperature/Humidity and Salt Fog requirements per Mil-C-48497A.

“Galvo mirrors are a perfect fit for our highly-durable reflective coating designs. Since application environments can range from ambient and controlled to harsh military conditions, one can be assured that our coatings will function as designed” says Forrest Reynard, President of Reynard Corporation.

Optical Heated Windows High optical transmission with matched impedance

San Clemente, CA – Reynard Corporation, a leading global supplier of optical components and thin film coatings, creates custom optical heated windows utilizing conductive materials.  Heated windows are the most cost effective way to keep imaging planes or optical instrumentation windows free of moisture or fog.

 

Our heated window patterns can be customized in design to achieve high transmission and/or matched impedance to meet the requirements of most any system.  The substrate size, shape, and type can also be customized to meet the necessary requirements.  Bus bars added to the edge of the optics provide solder points for electrical leads.  Adding an anti-reflection coating to one or two sides of the optic provides enhanced transmission while providing an extra layer of protection to the conductive surface.

 

Several types of heated windows are available:

• Solid ITO: Provides a highly transparent and conductive film over the surface of the optic for visible and NIR wavelengths.  The controlled thickness of the applied ITO controls the impedance.
• Lines: Bus bar to bus bar lines, typically required to be matched in length, for controlled impedance.  These lines can be applied from either ITO or highly conductive metals, such as gold.
• Grids: Grid patterns provide a balance between impedance control, high transmission, and robustness.  Grid patterns are typically used when the optic is in environments where the gird surface can be scratched, yet impedance control needs to be maintained.  Patterns can be applied from either ITO or highly conductive metals.

 

Key features include:

• Customized or standard patterns, down to 10um line widths
• Use of highly conductive materials, such as ITO or gold
• High transmission in desired wavelength spectrum, from visible to far IR
• Application to most substrates, including thick optics, plastics, and flexible membranes

 

“Without a heated window, condensation buildup in the viewing window of an imaging system could deem the entire system ineffective”, says Forrest Reynard, President of Reynard Corporation. “Systems that quickly traverse from cold to warm environmental conditions see condensation buildup due to slow thermal mass changes in the system compared to the external environment.  Heating the imaging window so that it thermally matches external environmental conditions eliminates condensation buildup.”
