2D Drawing


MSB3000 Miniature Fiber Spectrograph is for ultraviolet,visible,near infrared spectroscopy measurement of an information apparatus.Compared to conventional spectrophotometer,the main features of the spectrometer to measure speed,the whole spectrum of information received simultaneously;repetitive,and most of the equipment used all-solid-state design,not the activities of components to ensure repeatability and measurement equipment for a long time to run the stability of the CT machines used in this cross-optical,compact,small portable devices.The main measurement used in emission spectrometry,measuring absorption spectra,fluorescence excitation spectroscopy,and so on. Micro-spectrometer is widely used in a variety of light detection,color measurement,chemical analysis,the glass lens reflex transmission measurement,chemical analysis of the dynamics,the university teaching laboratory demonstration,gem identification,enviromental monitoring,gas analysis,a variety of analytical instruments such as OEM parts.


MSB3000 Miniature Fiber Spectrograph is compact,including the incident slit,collimating lens,grating,mirror image,and the filter array detectors,also includes data acquisition systems and data-processing system.After the incident optical signal to the projection slit collimator lens,astigmatism will be made into a quasi-parallel to the optical reflection grating,the dispersion after the mirror imaging spectroscopy was in the array of receivers to receive the surface to form  spectrum of surafce spectrum.

Spectrum of monochromatic light spectrum is the face of the sequence of arrangement(with high-level spectrum),the whole spectrum of any exposure to a small band corresponding to the pixel detector,in the light signal will be coverted into electronic signals,by Analog-to-digital converter,A/D amplification,by the end of electrical control system showed that the output terminal.In order to complete a variety of signal spectrum.


  • Fixed grating design;the traditional instruments through the grating rotation to scan the entire spectrum;and the use of micro-spectrometer CCD array receivers to achieve a fixed grating structure design,to achieve high repeatability and instruments to achieve long-term stability.
  • Optical interface standard:SMA905 standard optical interface.FCinterface can be used to enter or lens coupling interface(user);
  • Scanning speed:full-wavelength scanning of the fastest 5 milliseconds,the real dynamic analysis;
  • The entire electrical system for the control of dual-CPU,a CPU-driven control of CCD,a CPU control data acquisition and transmission.Effectively improve the measurement of speed,to achieve rea-time spectrum acquisition and display.
  • USB2.0 interface:the fastest 40M bps;
  • RS232 interfaces;
  • USB 3000-spectrometer to measure the speed of the fastest spectrometer,can be scanned 200 times per second.
