The TMc300 range of monochromators control grating position using precision gears and a microprocessor-controlled microstepping drive. Up to three gratings are mounted on a turret which can be rotated through 360° allowing software selection of grating type and position.
A programmable detector changeover mirror and detection electronics with software selectable dual inputs allow spectral scans over wide wavelength ranges to be accomplished without manual intervention. The advantages of this drive include constant wavelength accuracy at all grating angles, very fast wavelength acquisition and zero backlash.
