Abstract
It is shown that the effects of thermal expansion of the grating and sine drive in a monochromator can be made to cancel exactly by proper mounting of the drive screw, and by choosing the material of the drive arm such that its thermal coefficient of expansion just equals the sum of the coefficients of the grating and drive screw.
