ABSTRACT OF THE DISCLOSURE A cam filter wheel apparatus disclosed for tilting interference filters in order to achieve variation in the light wavelength transmitted by each filter. The wheel apparatus contains a number of filters each mounted so as to pivot and change its inclination with respect to an incident light beam as the filter wheel rotates each filter through the light path. The pivot motion is achieved by a cam follower associated with each filter which rides on a stationary cam track.
