What is a dual blaze spectrometer grating?
A dual blaze grating is a grating with two blaze wavelengths. The SILVER-Nova Super Range spectrometer has a composite grating with a dual blaze at 250 and 1000 nm, giving it a wavelength range of 190-1110 nm. This can be seen in the grating efficiency curve: View...What is a spectrometer’s Blaze Wavelength?
The blaze wavelength is the wavelength at which the grating is most efficient. Take a look at the grating efficiency curve for the UV BLUE-Wave spectrometer model: This grating is most efficient at 300 nm, so the blaze wavelength is 300 nm. This is determined mostly...What is a spectrometer slit?
The slit is an opening that controls how much light enters the spectrometer. The width of the slit affects resolution; the narrower the slit, the higher the resolution. However, narrower slits also decrease signal strength. These two factors must be balanced when...What is Full Width at Half Maximum (FWHM)?
The full width at half maximum (FWHM) is the width of a line shape at half of its maximum amplitude, as shown below: A closely related quantity is the half width at half maximum (HWHM) or the Resolving Resolution and it is half of the FWHM. For Gaussian line shapes,...
