You probably from time to time need to do some quick evaluation of various optical designs for a spectroscopic system. And you don’t want to spend days running a full numerical calculation tool like Zemax or CODES.

Very often, you need to cover a specific wavelength range with a certain resolution and want to evaluate how different detector widths, grating groove densities, and image magnifications will affect your focal lengths and slit sizes.

To do that, we have created a handful of guides and calculators that we ourselves find very useful.

The calculators can be downloaded to you desktop or mobile device for free. For Raman spectrometers, the range and resolution are specified in inverse cm-1, so we added a calculator to convert from Raman shift in cm-1 to wavelength in nm. We hope that these tools will help you in your daily work.
