Reynard Corporation, a global supplier of optical components and thin film coatings, announces the Bullseye inverted apodizing neutral density filter. This filter is part of the Bullseye Apodizer line of customizable gradient filters. These filters eliminate undesirable intensity variations in optical systems. The density of the filter increases radially from a clear center, where light is usually at its peak intensity, to the outside edge, where it can becomes completely opaque.
The Bullseye apodizing filter can be designed for most distribution functions, such as a Gaussian function, regardless of the size of the beam. The distribution function, substrate type, and bandwidth are a function of the customer’s specific requirements.
Key features include
- Density gradients can be customized to suit any application
- The filter can be applied to a number of different substrate types
- Can be designed to be used from the UV to the Far IR.
Inserting a Bullseye apodizing filter at the aperture stop of your imaging system modifies the intensity variations of your light source which can result in the elimination of edge diffraction patterns.
- Application examples are found in diverse industries, such as:
- Entertainment - To make light distribution uneven for cosmetic applications.
- Imaging - To break up diffraction patterns by the introduction of soft edges.
- Photography – To create soft edged in pictures
- Industrial – To make sensors more sensitive in the center of the field of view
- Astronomy – To reduce high intensity light sources around the featured object
Established in 1984, Reynard Corporation designs and manufactures precision thin film optical products for a global customer base, both military and commercial. In-house operation capabilities include design, fabrication, photolithography, coating, and sub-assembly for a one-stop solution.
