Achieving geometries as small as 5 microns utilizing a variety of thin film transparent-conductive materials

Reynard Corporation announces custom photolithography services to manufacture patterned optics. Our contact exposing technique can achieve geometries as small as 5 microns utilizing a variety of thin film coating materials. Metallic or dielectric materials are selected based on the application’s transparent, reflective, and/or conductive opto-electrical requirements. Patterns can be applied to most substrate materials, including plastic sheeting.

Reynard Corporation announces custom photolithography services to manufacture patterned optics. Our contact exposing technique can achieve geometries as small as 5 microns utilizing a variety of thin film coating materials. Metallic or dielectric materials are selected based on the application’s transparent, reflective, and/or conductive opto-electrical requirements. Patterns can be applied to most substrate materials, including plastic sheeting.
Patterned optics are utilized in diverse markets and in numerous applications, such as:
 
Elimination of Electro-magnetic Interference (EMI) for sensitive electro-optical systems - In this case, the coating material is a conductive metal. The size and spacing are designed for maximum protection at a specified frequency band, while providing high transmission in the visible range.  This design approach is utilized in the manufacturing of high-performance aircraft windows.
 
Heated windows to reduce or eliminate fogging in multi-atmospheric systems - The conductive patterns are used as heating grids that are connected to bus bars on two sides of the substrate surface.  These windows will heat up when exposed to low-voltage, high-current sources.  This design approach is utilized in high-altitude anti-tank missile windows, as well as in the tip of endoscopes for the medical market.
 
Wideband beamsplitters that operate from UV to Far IR – An evenly distributed pattern is made of many small transmission holes or blocking dots to split the energy of the radiating source.  An even split of energy is achieved when the density of the transmitted region matches the density of the blocked region.  The split in energy can be changed by changing the ratio of the transmission region to the density of the blocking region.
 
Other applications include: Encoder disks, LCD displays, bar codes, reticles, transducers, and precision reference targets.
 
“Combining advanced thin film optical coatings with precision photolithography patterns allows for both the creation of novel optical solutions, as well as a reduction in the number of optical elements in a system, which saves in system space and cost.” Says Forrest Reynard, CEO of Reynard Corporation.

Substrates to 18” diameter can currently be accommodated. Please contact our Sales Department for further information (949)366-8866, This email address is being protected from spambots. You need JavaScript enabled to view it..
