Abstract:
An optical system for separating multi-wavelength light into first, second, and third component parts, comprising:a first prism for receiving said multi-wavelength light, for internally reflecting said first component part, and for passing said second and third component parts into a first gap; a first reflector for reflecting said second and third component parts in said first gap back into said first prism; a second prism for receiving said first, second, and third component parts from said first prism, for internally reflecting said first and second component parts, and for passing said third component part into a second gap; a second reflector for reflecting said third component part in said second gap back into said second prism; a third prism for receiving said first, second, and third component parts from said second prism, for internally reflecting said third component part, and for passing said first and second component parts into a third gap; a third reflector for reflecting said first and second component parts in said third gap back into said third prism; a fourth prism for receiving said first, second, and third component parts from said third prism, for internally reflecting said second and third component parts, and for passing said first component part into a fourth gap; and a fourth reflector for reflecting said first component part in said fourth gap back into said fourth prism; wherein said first, second, and third component parts pass from said fourth prism.
