| Title: |
Spectral Filter Module |
| Abstract: |
Spectral filter means in which filter elements have elongated planar
surface areas covered with patterns of filtering material. Filter elements
are independently movable parallel to their respective surface planes to
positions where a given density pattern of filtering material is
intersected by a beam of light and filters a given component of the light.
Separate filter elements for each of the primary colors and an additional
element for dimming all colors are used to control the color and intensity
of a beam of light.
