%WAVEMETERV2NM Convert analog out voltage to wavelength
% The Burleigh WA-1500 has an analog output that gives a voltage according
% to the formula:
% V = .0049*(wavelengthInNm-setPoint)/analogRes+Offset
% where analogRes = .0001, and the setPoint must be supplied to the
% function. wavemeterV2nm(analogVoltage,setPoint) converts the analog
% voltage voltage measured at the output to the wavelength in nm, given the
% setPoint. 
% The set point can be found by running the function getSetPoint(wa1500).
% Note that a small correction may be needed to calibrate the specific
% wavemeter that is used. Go into the source for this code, and change the
% variable 'corr' to calibrate your wavemeter.
