Description

Optical multiway analyser with high spectral resolution

The present invention is a kind ofly transformed universal optical MCA (OMA) optical multichannel analyzer of high-spectral-resolution measurement into, and this instrument is applicable to the measurement and the research of various high-resolution spectras, is specially adapted to the measurement to transient state and weak light source.

OMA is the emerging equipment that occurs in recent years, and it is comprehensive spectrograph and photoelectric spectrophotometer advantage and the present state-of-the-art general spectroscopy equipment that forms.Its light harvesting spectrum information collection, processing, store, be shown in all over the body, can do almost various types of spectrum work, two-dimentional OMA still can make visual brightness definite value and analyze and handle., because OMA is the first generation product of spectrograph and photoelectric spectrophotometer comprehensive development, therefore still having self needs perfect place, also has it to adapt to the problem that new spectral investigation field needs solve.Its intermediate-resolution is low to be great deficiency.In addition, because present photoelectricity multiple tracks probe size is limited, the effective length of generally popping one's head in is 12.5mm or 2.5mm, so exist between while spectrum width and resolution when causing as spectral measurement contradictory.If adopt the bigger beam splitting system of linear dispersion, then resolution can be higher, but once adopt simultaneously spectrum width just narrow, otherwise if the beam splitting system linear dispersion is little, spectrum width can be wide, but resolution is low.The universal optical MCA is taken into account both, and the beam splitting system linear dispersion is about 20～30 dust/millimeters, and its while spectrum width is that their true resolution is about the 2 Izod right sides about 300 dusts (to the long probe of 12.5mm) or 600 dusts (to the long probe of 25mm) approximately.Such resolution is not enough to many spectrum work, says nothing of the high-resolution work of doing.

The optical multichannel analyzer (OMA) that the purpose of this invention is to provide the low spectrum resolution of a kind of usefulness transforms the optical multichannel analyzer that high-resolution spectra is measured into, it is to install an optical accessory additional in general purpose O MA system, under self-programmed software control, can be implemented under the prerequisite of spectrum width when not reducing former OMA, obtain the high-resolution spectroscopy of each bar spectral line in this wavelength region may, its resolution improves one to two magnitude than original OMA, can reach below the 0.007nm.
