摘要: An electromagnetic energy measurement apparatus and method for measuring first, second, and third wavelength components includes first and second coated optical elements having non-parallel surfaces. Proper selection of the parameters of the optical elements reduces the level of coma and astigmatism in the apparatus. Additionally, filters pass the first, second, and third wavelength components to first, second, and third sensors. Improvement in the alignment of the field of view between sensors is realized by applying an adjustable compressive force on the filters to individually adjust the field of view.
