The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

Laser tuning gratings are holographic gratings specially designed for wavelength tuning of lasers, such as dye lasers, Ti-sapphire, or external cavity diode lasers. The groove depth is optimised to ...

Light scattering as the basis for size determination of many objects has been explored for a long time. It was Gustav Mie, author of the Mie Scattering Theory, who studied gold nanoparticles in ...

The efficient generation of light in the extreme ultraviolet and soft X-ray region is an important step in the road map for the semiconductor industry. This is because of diffraction, which limits the ...

New range of 405nm wavelength stabilized laser diodes for applications which include Raman spectroscopy, flow cytometry and metrology / interferometry. The 405nm blue-violet wavelength stabilization ...
