Patent ID: 8330087

Claim:
A multispectral detection system for use with image-forming optics configured to form an image of a sample, the detection system comprising: an imaging detector; relay optics comprising multiple optical elements, the relay optics positioned to relay the image formed by the image-forming optics to the imaging detector; an actuator coupled to one of the optical elements in the relay optics and configured to adjust a position of the coupled optical element, wherein the coupled optical element has optical power; and control electronics configured to cause the actuator to adjust the position of the coupled optical element in the relay optics in response to a wavelength band selection by a wavelength selection element positioned to select one wavelength band for the image from among two or more different wavelength bands within an overall wavelength range, wherein the adjustment to the position of the coupled optical element varies depending on which of the different wavelength bands is selected by the wavelength selection element.
