1 March 1966 An Instrument for Determining the Lens Spectral Transmittance

The variety in the spectral sensitivities of photoreceptive materials in current use today requires close control of the spectral transmittance of lenses for proper systems design. A device utilizing second order narrow band interference filters is described in which the spectral transmittance of compound lenses can be quickly and accurately determined, at a series of discrete wavelengths, by a relatively unskilled operator through a semi-automatic push-button operation.
