Design and Realization of Micro Fiber Spectrometers for Bioluminescence Detecting Systems' Stray Light Detection

The paper concerns about the principle and the optimizing design method for optical system of micro fiber spectrometer, which suits for stray light detection of bioluminescence detecting systems. By choosing asymmetrical crossed czerny-turner (CZ) configuration as the basic optical structure and selecting system parameters according to the allowance of system's aberrations and the dimensions of CCD detector, we developed a micro fiber spectrometer based on planar grating with a working wavelength range between 330 nm and 930 nm. system's spectral resolution is up to at least 0.5 nm according to actual measurement (50 um).
