Optical system and method for optically analyzing light from a sample
View Patent ↗An optical system for analyzing light from a plurality of samples is provided. The optical system includes a plurality of holders adapted to have samples located therein, a collection lens, a transmission grating, and a reimaging lens. The collection lens is configured to receive and substantially collimate light from the samples. The transmission grating is configured to spectrally disperse the substantially collimated light from the collection lens. The reimaging lens is configured to receive the light from the light dispersing element and direct the light onto a light detection device. A method of optically analyzing at least one sample is also provided.
1. A system for collecting fluorescent light emitted from a biological sample, the system comprising:
a plurality of sample holders;
a light detection device; and
an aspherical optical element, the aspherical optical element comprising:
a flat surface facing the plurality of sample holders;
a curved surface facing away from the plurality of sample holders; and
a radius of curvature,
wherein the sample holders are positioned at an object plane of the aspherical optical element, wherein the object plane is within the radius of curvature, and wherein the light detection device is a spectrograph for the fluorescent light from each of the sample holders.
2. The system of claim 1 , further comprising a collection lens positioned to receive and substantially collimate light from the curved surface of the aspherical optical element.
3. The system of claim 2 , further comprising a transmission grating configured to spectrally disperse the substantially collimated light from the collection lens.
4. The system of claim 3 , further comprising a reimaging lens configured to receive the spectrally disperse light from the transmission grating and direct the spectrally dispersed light onto the light detection device.
5. The system of claim 4 , wherein the light detection device is a CCD.
6. The system of claim 4 , further comprising an aperture positioned between the collection lens and reimaging lens.
7. The system of claim 6 , wherein the aperture is configured to provide uniform light throughput.
8. The system of claim 7 , wherein the aperture is in the shape of a cat's eye.
