Optical absorption spectrometry system including dichroic beam combiner and splitter |
摘要 |
An optical absorption spectrometry system includes first and second light sources, a dichroic beam combiner and a wavelength selective module. The first light source emits first light having first wavelengths within a first wavelength range, and the second light source emits second light having second wavelengths within a second wavelength range different from the first wavelength range. The dichroic beam combiner includes a predetermined first reflectance/transmission transition region, the dichroic beam combiner being configured to transmit a first portion of the first light and to reflect a second portion of the second light to provide combined light. The wavelength selective module is configured to disperse the combined light received at an entrance aperture, to select a sample wavelength range of the dispersed light as sample light, and to output the sample light having the selected sample wavelength range from an exit aperture for illuminating a sample. |

1. An optical absorption spectrometry system, comprising:
a first light source configured to emit first light having first wavelengths within a first wavelength range; a second light source configured to emit second light having second wavelengths within a second wavelength range different from the first wavelength range; a dichroic beam combiner comprising a predetermined first reflectance/transmission transition region, the dichroic beam combiner being configured to transmit a first portion of the first light and to reflect a second portion of the second light to provide combined light; and a wavelength selective module configured to disperse the combined light received at an entrance aperture, to select a sample wavelength range of the dispersed light as sample light, and to output the sample light having the selected sample wavelength range from an exit aperture for illuminating a sample. |
