The original version of PCSpectraLite was written in 2003 by Intelligent Interfaces for analysing spectra from the Elliott Instruments TVSPEC spectrometer, now no longer available. It could analyse images of up to 2048 pixels wide by 2048 pixels high.

The latest version of PCSpectraLite was written by Andy Ray Developments for analysing spectra from the Elliott Instruments CCDSPEC spectrometer, now no longer available, and can analyse images of up to 6144 pixels wide by 4096 pixels high.

PCSpectraLite is the ‘lite’ version of PCSpectra.

It can:

load the image from a 24 bit colour bitmap bmp format file;

save the image in a bmp format file;

print the displayed image;

close the image;

show the X and Y co-ordinates, the Wavelength (if a SpecCal.txt file exists) and the Intensity of the image. Additionally, show the Greyscale value of the displayed image.

display information about the image;

change the size of the displayed image;

invert the displayed image;

define a region of interest for analysis using the mouse;

display the Spectrum (X Axis Projection) of the region of interest of the image;

save the displayed Spectrum in a bmp format file or save the displayed Spectrum as data in a csv format file;

print the displayed Spectrum;

display the Profile (Y Axis Projection) of the region of interest of the image;

save the displayed Profile in a bmp format file or save the displayed Profile as data in a csv format file;

print the displayed Profile;

calculate and display the centroid and the number of pixels above the threshold value for the region of interest;

set the data thresholds;

display information about the program.
