Spectrometer Evaluation Tools

 

iPhoneYou 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 on 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 ...

Precision Control Over Your Spectrometer

– a Necessity for Your LIBS Instrument

Laser Induced Breakdown Spectroscopy (LIBS) is an extremely versatile spectroscopic technique which can be used to analyze the atomic composition of virtually any material. In a LIBS system, a short laser pulse is used to ablate material from the surface of a sample. The laser pulse energy will be high enough to create bright plasma on the surface of the sample.

When choosing a spectrometer ...

Scaling of wavelength range in transmission grating based spectrometers

 

This note describes how an existing spectrometer wavelength range can be scaled by changing the groove density of the transmission grating, without needing to change other aspects of the design. The starting point is a known spectrometer with a grating with groove density G0, detector width LD, and covering the wavelength range λmax,0 – λmin,0.
 
The focal length of this spectrometer is given by:  ...
