Reynard works with a wide variety of exotic substrate materials to achieve peak performance in an optical component. Besides regularly working with all standard visible and infrared materials, our substrate fabrication department is skilled in the particular handling, polishing, and shaping of exotic materials such as:
- Indium Antimonide (InSb)
- Indium Arsenide (InAs)
- Indium Gallium Arsenide (InGaAs)
- Indium Phosphide (InP)
- Mercury Cadmium Telluride (HgCdTe, MCT)
- Zinc Selenide (ZnSe)
- Zinc Suflide (ZnS)
- ... and more
Substrate fabrication is the process of turning bulk, raw, optical materials into high-precision optical components, meeting stringing design requirements. We regularly work on a wide variety of substrate materials from common to exotic and from soft to hard. Mostly, we work with plano (flat) optics, although we are able to produce hand-crafted spherical products as well. The on-going addition of fabrication manufacturing equipment expands our capabilities and capacity.
Stacked filters are a unique product offered by Reynard that utilizes the optical characteristics of filter glass to produce a precision optical component. These filters are designed utilizing custom built software that scours a database made up from thousands of types of filter glass from several glass manufactures. A merit function identifies the best combination of two or more glass types that meet your design requirements. The main advantages of stacked filters are that they perform at very wide angles and are extremely durable.
Reynard has a long legacy of producing innovative optical thin film coatings that have served diverse markets such as telecommunications, medical, aerospace, defense, laser, and vision. Our custom coatings utilize design databases that are tuned to the characteristics of our deposition coating chambers, resulting in close-to-theoretical measured performance. Provide us with your particular specifications or needs, and we will provide you with Engineering feedback and a theoretical design that best meets your requirements.
We have developed several processes for the application of metallization on an optical component. Robust designs that include Platinum (Pt) or Gold (Au) have been tested in environmental extremes, showing ultra-high tensile adhesion, yet easy for soldering. Other designs have successfully passed the Getter process. Metallization can be added for bus bars, planes, or patterns, always meeting the requirements of your optical needs.
