A number of turret configurations are available.  Some turret configurations are not available in some monochromators due to mechanical limitations.

1G turrets allow for manual grating selection.  Each grating is mounted on a kinematic grating holder that can be easily removed and swaped for a different grating.

3G turrets allow for motoroized grating selection.  Up to 3 gratings are mounted on a cassette.  The cassette rotates perpendicularly to the axis of rotation of the sine drive.  The cassette can be replaced with other cassettes allowing for unlimited grating options

There are three basic parameters to consider when choosing a grating for your standard series monochromator

 

 A) Required Wavelength Range

 

The wavelength range available to you is determined by the grating groove density chosen and the angular mechanical limitation of the monochromator.


 B) Grating Efficiency

 

Ruled gratings may be blazed to increase their efficiency over a specific wavelength band.  Holographic gratings can be modulated such that they are more efficient at some wavelengths then at others.  Grating efficiency curves are the best tool for determining the most efficient grating available for your application.  It is important to note that grating efficiency curves do not represent the exact efficiency that should be expected when the grating is used in a monochromator as grating efficiency curves are taken at Littrow angle. 


 C)    Required Resolution and Bandwidth

 

Resolution is a measure of an instrument’s ability to separate adjacent spectral lines.  Resolution is generally given in nm.  The bandwidth (or bandpass) is the wavelength range that falls on the output port at any one time and is also given in nm.  This is an important parameter when integrating a camera such as a linear array or CCD on the output port of the monochromator.

 

 

  

Standard mirror coatings are aluminum with a MgF2 protective layer.  Standard gratings have an aluminum coating.  metallic coating.  If your application would benefit from different mirror or grating coatings please refer to the codes below at the time of order.
