Security Considerations!
The Monochromator contains delicate optics.Do not open the
monochromator lid if not needed!
Do not tough or breathe over gratings!
Never try to clean mirrors or gratings！

5. Installation & Operation
5.1. Installation
5.1.1 USB Software Installatio
XP and Win7 system：
1. Firstly ensure the Power switch on the rear of the spectrograph is set to 0.
2. Connect the Power & USB cables.
NOTE: Do not switch on the spectrograph at this stage.
3. Connect the other end of the USB cable to the PC and plug in the power supply to the mains, but
do not switch the power on.
4. Put the CD into the PC CD-ROM,switch the power on to the spectrograph.A dialog box should then
appear as the following:
5. Select the Install from a list or specific location (Advanced) option then click Next>. A dialog box
similar to the following should appear:
6. In the Browse Folder dialog box, find the USB driver in the CD and install it. IF your PC is 64-bit,
please select USB Driver-64 bit.

5.1.2 Connecting the spectrograph
a. Firstly ensure the Power switch on the rear of the spectrograph is set to 0
b. Connect the Power & USB cables.Connect the other end of the USB cable to the PC and plug in
the power supply to the mains, switch the power on and install the USB driver as USB SOFTWARE
INSTALLATION.
c. Remove the input slit and output slit covers from the spectrograph, e.g.:
d. Fitting the light source to the input slit. Then the system will be as Tunable Light Source. We can
supply Deuterium, Multiplex,Tungsten-Halogen and Xenon light source.
e. Fitting the detector to the output slit, we can supply Photomultiplier,Silicon Series
Detectors,InGaAs Series Detectors and so on.
f. Open the light source, spectrometer, data collector power, open the CTL-C1 or Zolixscan
scanning software , you can begin to use.
5.2. Accessory Operation
5.2.1 Slit
Micrometer
The micrometer knob is graduated in 0.010-millimeter (10µm) increments. Each clockwise revolution
of the micrometer knob increases the slit width 0.25 millimeters (250µm). Refer to the side drawing.
The micrometer knob should not be rotated below a reading of 0.00 or above 3.00. A micrometer
setting of less than 0.010 millimeters (10µm) should not be used, because a stop is provided to
prevent the slit jaws from contacting each other.

Slit house
The width of the slit is one of the most important parameters for resolution of the monochromator. The
slit width of each bilateral slit assembly is adjustable from 0.010 millimeters to 3 millimeters (10µm to
3,000µm) by a micrometer located on the top of the slit housing. For maximum reproducibility, the slit
width should be set in a clockwise direction (increasing slit widths) each time it is changed.
Note: Damage may be done if slit jaws are opened wider than 3.0mm.

★The reference wavelength of the 3600 grating gratings in the table is 253.65nm, and the reference
wavelength of the rest of the grating gratings is 435.833nm, and the dispersion corresponding to
different wavelengths is different;
★The spectral range is not only related to the mechanical scanning range, but also to the raster
shine wavelength；
★The resolution values listed in the table are not all given at the same wavelength, and the specified
detection wavelength is the standard wavelength near the wavelength of the blaze.
5.2.3 Shutter Operation（Options）
1. The shutter in the spectrograph can be set by ZolixScan software, click on the Monochrometer A
Digital Port.

Spectral Bandwidth and Slit Width Comparison Table
14
Zolix Instruments Co., Ltd. http://www.zolix.com.cn E-mail: [e-mail]
6. Spectral Bandwidth Calculation Formula
Spectral bandwidth = slit width X Reciprocal Dispersion
NOTE1, This formula only for slit width ＞100μm.
NOTE2, The real measurement bandwidth value slightly more calculation value.
NOTE3, The Reciprocal Dispersion of different spectrograph are shown in the SPECIFICATION
table,and the Reciprocal Dispersion value only for 1200g/mm gratings. So you need the below
formula to calculate other groove density gratings:
Real Reciprocal Dispersion = Reciprocal Dispersion value in the SPECIFICATION table X 1200/ real
grating groove density
e.g.1: For Omni-λ300 monochromator with 600g/mm gratings
Real Reciprocal Dispersion =3.6×1200/600=7.2nm/mm
When the slitwidth is 2mm, the spectral width =7.2×2=14.4nm
Also, according to above formula to calculate the slit width of fixed spectral width
