摘要： The present invention provides a grating photometer comprising a light splitting box a preamplifier box, a photodiode array and optical assembly. The light splitting box has a light splitting chamber. There are provided a first extinction hole and second extinction hole respectively on the side wall of the light splitting chamber and on the preamplifier box to correspond to zero order spectrum line. The first hole is a through hole and the second hole is a blind hole the configuration of the first and second extinction holes direct the zero order spectrum to go into the second extinction hole, as a result, generates a rather small number of stray light in the light splitting chamber coming from the scattering of the zero order spectrum from the second extinction hole, thus suppresses effectively the stray light and improves tho signal-to-noise ratio of the photometer.

摘要： A spectrophotometric optical system of a microplate reader and a filter wheel thereof are disclosed. The filter wheel comprises a pivotable wheel body, at least one narrow-band filter with a relatively long central wavelength mounted to the wheel body, and at least one narrow-band filter with a relatively short central wavelength mounted to the wheel body. The narrow-band filter with a relatively long central wavelength is provided with a diaphragm on a front surface thereof The diaphragm is formed with a plurality of apertures. By the diaphragm attached to the front surface of the narrow-band filter with a relatively long central wavelength, an energy matching between light of longer wavelength and light of shorter wavelength may be achieved. Further, due to the uniformly distributed apertures in the diaphragm, an even light spot may be obtained.
