Basic configuration including fiber optic spectrometer includes a 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.
The choice of fiber optic equipment
grating spectrometer grating depends on the spectral range and resolution requirements.
For the fiber optic spectrometer, usually in the 200 - nm - spectral range
Due to demand higher resolution can be hard to get broad spectrum scope;
At the same time, the higher the resolution requirements, its luminous flux will be less.
For low resolution and wider spectral range, 300 lines/mm grating is usually the choice.
If the requirement is high spectral resolution, you can select 3600 lines/mm grating, or choose more pixels resolution of the detector.
Fiber optic spectrometer slit narrow slit can improve the resolution, but less flux;
Broad slit, on the other hand, can increase the sensitivity, but lose resolution.
In the different application requirements, choose the right slit width in order to optimize the whole test results.
Fiber optic spectrometer detector probe is in some ways determines the sensitivity and resolution of the optical fiber spectrometer, detector light sensitive area is limited in principle, it is divided into many small pixels for high resolution or divided into fewer but larger pixel for high sensitivity.
Back light sensitive CCD detector sensitivity is usually better, to a certain extent, so it can get better resolution in the case of no sensitivity.
Near infrared detectors due to high sensitivity and thermal noise itself, adopt the way of refrigeration can effectively improve the SNR of the system.
Fiber optic spectrometer with filter spectral itself multistage diffraction effects, the filter can reduce the interference of multistage diffraction.
Unlike conventional spectrometer, fiber optic equipment spectrometer is coated on detector, this part of the function in the factory need to install in place.
At the same time, the coating also has the function of antireflective improve the SNR of the system.
W Tek launched high sexual price CCD spectrometer.
It adopts high performance linear CCD array detector, with temperature compensation, a wide range of 200 - spectrum
1050 nm, using different slit, spectral resolution in 0.
Choose between 0 nm.
QuestTMX in ultraviolet/visible/near infrared, all has the outstanding performance, 200 -
Is 1050 nm spectrum, ultraviolet, visible and short-wave near infrared spectroscopy application ideal choice.
QuestTMX with temperature compensation, the lower the thermal drift to ~ 15 count / ℃, thereby effectively reduces the baseline drift, stability of the dynamic range.
QuestTMX reading speed is higher than 2.
0 MHZ, like yuan number 2048, built-in 16-bit digital conversion, the standard USB2.
0 high-speed data transmission, also can make it improve the RS232 serial port transmission, include external trigger and synchronization function, facilitate system integration and development.
QuestTMX series of flexible configuration, will meet more spectrum application requirements and the special requirements of OEM customers.
With technology speeding up in lighting speed, have created quite a name for itself amidst fiber optic equipment manufacturers and it happens to have a lot of benefits as well.
