Outside this range, the spectral lines may exhibit a degree of optical aberration (such as coma), which will become...

ANDOR an Oxford Instruments company Step 2b - Choosing The Right Grating vs Resolution & Band-pass The Shamrock 750 features an innovative triple grating turret, designed to offer flexibility and control over your choice and interchange of gratings. The triple grating turret can be easily and speedily removed, and replaced by an alternative turret with new gratings. The intelligent design of the 750 means that only a simple offset adjustment is required once the new turret and gratings are added. The 750 is shipped with the grating turret already in place, ensuring your system is ready for...
