Abstract:
1. An optical system for analyzing light from a plurality of samples, comprising: a plurality of capillaries, wherein the capillaries contain the plurality of samples and each sample in each capillary emits light in multiple colors during electrophoresis separation; a collection lens configured to receive and substantially collimate the light from the plurality of capillaries; a transmission grating configured to spectrally disperse the substantially collimated light from the collection lens; and a reimaging lens configured to receive the spectrally dispersed light from the transmission grating and direct the light onto a light detection device, wherein the system is configured to compensate for chromatic aberration in the spectrally dispersed light, the compensation comprising an optical axis of the reimaging lens being non-perpendicular with a surface of the light detection device.
