Spectroscopy Tools2 is another unit conversion utility, with some other useful functions related to spectrometers and lasers.

1) Unit Conversion - wavenumbers (cm-1) to nanometers (nm)

2) Line width conversion - given the center wavelength and line width in nm, the utility computes the line width in wavenumbers (cm-1).

3) Spectrometer Resolution - Given the wavelength range, number pixels, pixel width, and slit diameter, the utility will compute the resolution of the spectrometer.

This utility allows spectroscopist to do some common calculations.

I developed this utility because there were no other apps in the App Store that had the functions that I needed. So please contact me if you find this utility useful or need new functions.
