Dedicated software package (supplied with unit)
Installing the dedicated software package (containing sample software, device driver, DLL)*
11
into your PC allows running the
following basic tasks:
· Measurement data acquisition and save
· Measurement condition setup
· Module information acquisition
(wavelength conversion factor, polychromator type, etc.)
· Graphic display
· Arithmetic operation
Pixel number to wavelength conversion
Dark subtraction
Comparison calculation with reference data
(transmittance, reflectance)
Gaussian approximation
(peak position and count, FWHM)
Note: Two or more mini-spectrometers can be
connected and used with one PC
simultaneously.
*11: Compatible OS: Microsoft Windows
Professional Edition 2000
(SP3 or later) and XP (SP1a or later)
Device driver and DLL for controlling hardware are also provided.
You can develop your own measurement programs by using a software development environment that includes Microsoft Visual
C++ and Visual Basic.*
12
The DLL provides functions such as USB port open/close, measurement condition setup, measurement
data and module information acquisition.
*12: Operation of the device driver and DLL has been verified only with Microsoft Visual C++
and Visual Basic
.
