<p>An apparatus may have a light source configured to generate light, a reflector configured to collect the light and direct the light in a desired direction, a spectral filter assembly configured to receive the light from the reflector. The spectral filter assembly may have a stationary frame and a plurality of filter elements supported by the stationary frame. Filter elements of the plurality of filter elements may simultaneously filter a desired quantity of light within wavelength band to provide a filtered output light beam. A homogenizer may be configured to receive the filtered output light beam and produce a homogenized light beam having a substantially uniform irradiance distribution across a cross-section of the homogenized light beam.</p> |
