The stray light the advantages of optical fiber spectrometer is where?

Stray light is measured ultraviolet, visible and near infrared optical fiber spectrometer and a technology of infrared light intensity. Spectral measurement is widely used in various fields, such as color measuring, analysis of the concentration of the chemical composition of test or electromagnetic radiation, etc. Stray light optical fiber spectrometer generally include incident slit, collimating lens and dispersion components ( Grating or prism) , focusing optical system and detector. In the monochromator often including exit slit, make a very narrow part of the whole spectrum irradiation on single pixel detector. In the incident and exit slit of the monochrometer often fixed position and width adjustable, can be achieved by rotating grating to scan the entire spectrum. The advantage of stray light fiber optic spectrometer system of modularization and flexibility. Micro small stray light optical fiber spectrometer measurement speed is very fast, it can be used for on-line analysis. Universal detector and choose due to its low cost, so the cost of stray light optical fiber spectrometer is greatly reduced, thus greatly extend its application field. Introduction, stray light in fiber optic equipment spectrometer for each spectrometer has a grating selection table. How to understand the grating selection table are introduced. The spectral range of stray light fiber optic spectrometer depends on the starting wavelength and grating line logarithmic grating. The longer the wavelength, the greater the dispersion effect, covered with grating wavelength range. Stray light optical fiber spectrometer major challenge is not to make all the parameters in manufacturing high, but to make the technical index of the spectrometer in the three-dimensional space choice to meet performance requirements for different applications. This strategy makes the stray light optical fiber spectrometer can satisfy the customers with small investment to get large returns. The cube depends on the size of the spectrometer, specifications of the needed to achieve the size and the price of the product is related to the complexity of the spectrometer and spectrometer. Stray light optical fiber spectrometer products should meet the requirements of the customer technical parameters.
Many of us have heard about fiber optic equipment and seen some of these units in operation in china fiber optic manufacturer, fiber optic manufacturer and fiber optic products manufacturers spaces.
If you already use fiber optic equipment elsewhere or want the ability to offer restricted chat access to certain individuals, fiber optic equipment fiber optic equipment manufacturers offers you the most flexibility.
We focus on operational procedure and manufacturing facilities of fiber optic equipment.
If Fibra Opticas Tek Technology Co., Ltd. added selling plans, offered more fiber optic equipment, and increased service regions, it would suit the needs of more users.
