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.

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:  ...

Phase masks for 800 nm fs inscription

 

Ibsen has introduced a new Phase mask product. We are pleased to present that we have developed a technology that allows for the 0. order suppression of Phase masks optimized for 800 nm TE illumination. With 1000-1100 nm period Phase masks, this has not previously been possible.

The development project included a trial production lot of a sample Phase mask of this type, with the following specs:

Engineering Sample Phase mask specifications:

A limited number of this Phase mask is available for immediate ...
