Introduction
A compact spectrometer model ASP‐100M comprises a spectrograph, based on Cherny‐Turner optical scheme and a registration system based on a multichannel detector.
The ASP‐100M spectrometer may be used for various applications:
‐ laser wavelength monitoring
‐ plasma control
‐ precise spectral analysis of powerful light sources etc.
ASP‐100M features tunable registration spectrum area leading to increase in resolution over a wide spectral domain.
ASP‐100M is equipped with a multichannel detector based on a CCD array with pixel size of 8 ?/font>m x 200 ?/font>m that ensures high spectral resolution.

System Requirements
Minimum PC configuration: Pentium processor, monitor resolution 1024×728. Operational systems Windows98/2000/Me/XP.
 

Installation
1. Please remove the protective cap from the spectrometer input.
2. Place the device on clear horizontal surface.
3. Supply the monitored radiation to the spectrometer input by using the fiber cable or by directly lighting the input slit at right angle.
Important! Do not use fiber cable when measuring the femtosecond pulses due to signal modulation in fiber.
4. Install ReSpect software from the supplied CD following the instructions laid out in 獶river and Software Installation?section.
5. Connect USB cable to your computer and to the spectrometer.
6. Follow the instructions below from the paragraph: 玈oftware and driver installation?
7. You can find the information about ReSpect software and its functionality in the 獺elp?submenu in the program itself.
8. Refer to 揝ynchronization?section for sync options.
 

Software and Driver Installation in Windows XP
1) Please insert the installation CD into your CD‐ROM drive.
2) Connect the spectrometer to your PC via USB port.
3) The operational system will find the new device and show the message in the lower right corner of
the screen 玁ew hardware found? Then the following window will appear on the screen:
Please select 玁o, not this time?and press 玁ext?
In the next window select 獻nstall from a list or specific location?as shown in the picture:
Press 玁ext?
 

In the following menu:
Indicate the location where the drivers of the device are. Press 揃rowse? then select your CD drive
letter (with the installation disk inserted), and then choose folder 獶river? Then press 玁ext?
Press 揅ontinue anyway?in the next window
The installer will then ask for the 揝LLOADER?and (or) 搖sb2ph?files, they are also located in the
揇river?folder of the installation CD.
After the installation click 揊inish?
4) If the window 揊ound New Hardware?appears again then please repeat the Step 3.
5) Install and run 揜eSpect?br> (CD‐drive:\ ReSpect‐1.7.1.0‐Ormins\ReSpectSetup‐1.7.1.0‐Ormins_1.exe)
 

Basic functions
1) Single measurement: Run Single
2) Continuous scanning: Run Endless
3) Background signal subtraction: Take baseline
4) Exposure setting (7 ?20000 ms):
Or click button on the control panel and set the necessary exposition time:
5) Spectral sensitivity correction:
(if the tick is present at 揃ypass?then the correction is OFF, if there is no tick, then correction is ON)
6) Automatic record of last obtained data into a .dat file:
In the next window tick 揂uto export ASCII?item. The data of the last scanning will be automatically
recorded to the AutoExport.dat file, which is located in the root folder of the software.
P.S. The 揌elp?menu allocates many useful tips and full manual of the ReSpect software.
P.P.S. The software can also be used under Windows 98SE / Millennium /2000.
 

Synchronization
If the input pulse repetition rate is lower or equal to 10 Hz the camera needs to be synchronized by an
external trigger pulse with positive polarity, having amplitude of 5‐20 V, and leading the optical pulse by
>1 us. The external trigger is supplied to the camera via an included cable that is marked with an arrow
in the direction of the camera. The other cable that is marked with an arrow pointing in the direction
from the camera is used when it is necessary to use the internal trigger pulse of the camera itself.
The following actions should be taken after the cable is connected:
1) Select 揙ptions?and then 揝etup Driver? as shown below:
2) In the following window:
Select 揈xternal triggering?if you use the external trigger or 揑nternal with output sync?if you wish to
use the camera抯 own trigger pulse.
Click 揙k?
3) Then for single pulse measurement click 揜un Single? and for registering a sequence of pulses
choose 揜un Endless?in the 揂cquisition?tab as shown below:
 

Service and Maintenance
Your ASP‐100M spectrometer should only be serviced by staff qualified by the manufacturer.
The only user maintenance operation is external panel cleaning.
External panel cleaning
The cleaning should be carried out by a soft cloth slightly moistened in water or weak soap solution.
Do not use extremely wet sponges or fabrics.
Do not use abrasive materials or solvents as they can damage the paint.
