Abstract:
1. An imaging system for quantitative analysis of a microarray, said system comprising: a broad band excitation light source that provides Kohler illumination of said microarray at an incident angle that ranges from about 30 degrees to about 75 degrees from the normal to said microarray, and that has less than about ±25 percent variation in spectral intensity over said microarray at all wavelengths ranging from 400 to 800 nm; a support for holding said microarray; a detection lens system that is chromatically corrected so the apparent position of said microarray or a feature comprising said microarray varies by less than 10 μm as the detection wavelength varies from about 400 to about 800 nm; and a detection device for detecting and optionally recording an image produced by said detection lens system.
