STATS Consulting - Photographic and Scientific Imaging Filter Design and Development


Welcome To

STATS Consulting - OPTICS





Custom Filter Design for Photographic CCD Cameras:

Standard Red, Green, and Blue filters when used with silicon detectors produce a net response that is significantly different than the original red, green and blue filters themselves or the net response of these filters in combination with standard photographic films. This is due to the silicon detector’s disproportionately high response in the red and infrared as compared to the response of photographic film. To produce a given desired response (such as standard Kodak Wratten Red, Green, and Blue) a filter with transmission characteristics should be chosen so that when it is combined with the detector’s response and any other fixed optical elements in the optical pathway, the system will produce the desired response. STATS Consulting can help you design such filters matched to any desired Red, Green, or Blue.


Scientific Imaging Systems, Spectral Radiometers, Spectral Photometers, Colorimeters:

Photopic tri-stimulus x, y, and z system response can be achieved by carefully designed filter packs comprised of properly chosen glass types, thickness’, and coatings. Such filters for scientific imaging must reproduce the desired response to within a few percent at all wavelengths across the entire silicon chip sensitivity range (300 - 1200 nm, at 5 or 10 nm intervals). Sophisticated computer modeling combined with high speed software optimization allow STATS consulting to definitively select the best filter glass combinations to produce a laminated filter pack with the desired imaging transmission characteristics.


Custom Filter Design for Astronomical Imaging:

Astrophotometric UBVRI system response can be achieved by selection of high transmission glass types matched to your specific CCD response and taking into account the absorptive effects of the earth’s atmosphere.


Matching to Any Desired Response from Any Hypothetical Chip Sensitivity Function:

Accurate computer modeling of filter transmissions and CCD responses in your optical system can allow you to predict the effects of selecting different optical components, different CCD’s, and different filters -- without having to purchase or bench test these items.


Physical Specifications and Characteristics of Manufactured Filter Packs:

Filter packs would be composed of thin laminents of Schott, Hoya, and other Glass types, would be chemically stable, and would be scratch and bubble free to within design specifications. AR and other coatings optionally available.
