for optical devices with limited space, or for the most innovative optical designs benefitting from non-traditional filter geometries.

for optical devices where every micron of gap between a source of light and a sensor means reduced signal or increased noise.

for retrofitting simple or complex optical filter designs to any non-flat optical surface that challenges traditional coating methods.

for devices that can benefit from reduced substrate weight or a replacement of filter-coated glass components with plastic optics.

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.
