Miniature fiber optic spectrometer application what function machine characteristics

Optical fiber micro fiber spectrometer is usually used as the signal coupling, coupling to the spectrometer will be metering spectral analysis. Due to the convenience of the fiber, the user can build spectrum acquisition system very flexible. Miniature fiber optic spectrometer has the advantage of measuring system of modularization and flexibility. Miniature fiber optic spectrometer measurement speed is very fast, can be used for on-line analysis. And general detector with low cost, reduce the cost of the spectrometer, and thus reduce the cost of the whole measurement system. Basic configuration includes a miniature fiber optic spectrometer grating, a slot, and a detector. These parts of parameters when spectrometer of choose and buy must elaborate. Spectrometer performance depends on the combination of these parts and calibration, the calibration after the fiber spectrometer, in principle, these parts can't have any change. Miniature fiber optic spectrometer has extensive configuration choices, make its flow properties zui 'to meet customer demand. Miniature fiber optic spectrometer application what function machine characteristic spectral range: refers to the wavelength of light signal can be detected by spectrometer. Spectral resolution: can be fiber optic spectrometer distinguish the wavelength difference of small, zui, spectral resolution and the spectral range of the spectrometer, slit width and detector on the number of pixels, width and like yuan are closely related. Sensitivity: can be detected by spectrometer zui small light energy, it depends on the luminous flux of the spectrometer with the light sensor sensitivity of detector. Dynamic range: can be spectrometer to measure of zui big and zui the ratio of light energy. Signal-to-noise ratio, fiber optic spectrometer of the ratio of signal energy level and noise level. Spectrum access speed: at a certain level of the incident light energy, production of a fiber optic spectrometer to measure the signal and the time required to obtain spectra.
In today's world, have risen to an unexpected level of china fiber optic manufacturer. It has gained a lot of popularity and has come up with different kinds of variations in its content.
Satisfying our customers with the appropriate level of quality is a primary goal and a fundamental element as fiber optic equipment of our business mission.
Fibra Opticas Tek Technology Co., Ltd.'s main technology of fiber optic equipment leads us to understand and utilize information correctly.
