function [GlassName,nd,vd,dpgf] = zGetGlass(SurfaceNumber)
% zGetGlass - Requests data on the glass at a lens surface from the Zemax DDE server.
%
% Usage : [GlassName,nd,vd,dpgf] = zGetGlass(SurfaceNumber)
% 
% name is the glass name as a string, nd is the refractive index at the d line, vd is the Abbe dispersion and 
% dpgf is the relative partial dispersion. The last three are numeric.
%
% If the specified surface is not valid, is not made of glass, or is gradient index, the returned vector is empty.
% Data may be meaningless for glasses defined only outside of the FdC band.
