What is a spectrometer’s grating efficiency curve?
A grating efficiency curve shows how efficient a grating is at diffracting light at each wavelength. Below is a grating efficiency curve for the VIS BLUE-Wave spectrometer model: Absolute efficiency (%) is plotted versus wavelength. At 500 nm, the efficiency is ~75%....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...Introducing our new Applied Spectroscopy Division
