Description

A kind of high-resolution micro spectrometer
Technical field
The invention belongs to optical technology devices field, especially a kind of high-resolution micro spectrometer.
Background technique
Existing high-resolution spectrometer has that structure is complicated, volume is big or with high costs mostly, not only bad for Portable use, and expense is high, it is difficult to and high-volume configures.
With the progress in epoch and the raising of living standard, the requirement of food-safe, Environmental security of people etc. is got over Come higher, the standard of the detection of substance is also increasingly stringenter, high-resolution is convenient for carrying, the demand of the spectrometer of small size Increasingly urgent.Since high-resolution spectrometer equipment mostly uses greatly mechanical system to be scanned acquisition substance currently on the market Spectral information, the disadvantage in its large volume, quality increasingly displays, and the resolution of the spectrometer of small size in the market Rate is very low, is unable to satisfy the needs of people substantially.
Summary of the invention
The case where for the prior art, the purpose of the present invention is to provide it is a kind of implement it is reliable, compact-sized simple and point The high high-resolution micro spectrometer of resolution.
In order to realize above-mentioned technical purpose, the technical solution adopted by the present invention are as follows:
A kind of high-resolution micro spectrometer comprising the input optical fibre that is set in sequence along optical path, collimation lens, etalon array, Grating, plus lens and recipient.
Further, the recipient is CMOS recipient.
Further, etalon array surface plating is equipped with one-dimensional step substrate or two-dimensional stepped substrate.
One of embodiment as etalon array, it is preferred that the one-dimensional step substrate is the one of ten grades Grade step, every layer of difference 1nm~10nm height of the step substrate.
Using above-mentioned technical solution, the invention has the benefit that by etalon array surface plating set it is one-dimensional or Two-dimensional stepped is as substrate, so that the resolution ratio of spectrometer of the present invention corresponds to numbers of steps and improves and promoted, in addition, by mark The transformation of quasi- tool array improves so that the output of multiple centre of homology wavelength can be realized in the direction without changing incident light The construction compressible of spectrometer enables it that can miniaturise, and carries out processing criterion tool by optically coated form The step of array surface can not only reach machining high-precision, additionally it is possible to reduce processing cost and difficulty, keep its cost more low It is honest and clean, more conducively promote.
Detailed description of the invention
The present invention is further elaborated with reference to the accompanying drawings and detailed description:
Fig. 1 is the brief configuration schematic diagram of spectrometer of the present invention;
Fig. 2 is one of the implementation structure of etalon array of spectrometer of the present invention schematic diagram.
Specific embodiment
As shown in the figures 1 and 2, the present invention includes the input optical fibre 1, collimation lens 2, etalon array being set in sequence along optical path 3, grating 4, plus lens 5 and recipient 6, wherein the recipient is CMOS recipient.
In addition, in order to improve the resolution ratio of spectrometer of the present invention, 3 surface of the etalon array plating is equipped with one-dimensional step Substrate or two-dimensional stepped substrate 31, such as the spectroscopic optics system that 1nm is differentiated, using FSR=1nm, then being distinguished as 0.01nm When, 1nm can be divided into 100 parts by 100 steps, the resolution ratio of spectrometer can be improved 100 times in this way, realize two The promotion of the order of magnitude.
One of embodiment as etalon array, it is preferred that the one-dimensional step substrate is the one of ten grades Grade step, more preferably, every layer of difference 1nm~10nm height of the step substrate.
The present invention uses above-mentioned technical solution, sets one-dimensional or two-dimensional stepped conduct by the plating on 3 surface of etalon array Substrate 31, so that the resolution ratio of spectrometer of the present invention corresponds to numbers of steps and improves and promoted, in addition, by etalon array Transformation improves the knot of spectrometer so that the output of multiple centre of homology wavelength can be realized in the direction without changing incident light Structure compressibility enables it that can miniaturise, and carries out processing criterion by optically coated form and have array surface Step can not only reach machining high-precision, additionally it is possible to reduce processing cost and difficulty, keep its cost more cheap, more conducively It promotes.
The above is the embodiment of the present invention, for the ordinary skill in the art, religion according to the present invention Lead, without departing from the principles and spirit of the present invention all equivalent changes done according to scope of the present invention patent, repair Change, replacement and variant, is all covered by the present invention.
