Filter Manufacturing Technology
Everix's manufacturing platform is based on thermal drawing of a scaled-up multi-layer block (a preform) down to a substrate-free ultra-thin optical filter. This process is similar to how optical fibers are thermally drawn from a fiber preform and demonstrates scaling economics significantly better than the traditional coating-based methods of manufacturing optical filters. While we currently use this technology for small- to medium-size optical filters,

Why Everix Technology?
Everix' thermally drawn ultra-thin optical filters are best suited for applications where compact form factor, non-traditional geometries, angular shift reduction, light weight, and economic scaling are critical.
Compact & Complex Forms
for optical devices with limited space, or for the most innovative optical designs benefitting from non-traditional filter geometries.
Enhanced
Signal-to-Noise Ratio
for optical devices where every micron of gap between a source of light and a sensor means reduced signal or increased noise.
Conformal to Free-Form Optics
for retrofitting simple or complex optical filter designs to any non-flat optical surface that challenges traditional coating methods.
Light Weight
for devices that can benefit from reduced substrate weight or a replacement of filter-coated glass components with plastic optics.
Compensated Angular Shift
for optical devices that can benefit from an interference filter in a curved geometry to compensate for (and even completely eliminate) the undesired spectral shift of thin-film interference filters.
