Abstract
An optical arrangement includes an actuatable optical element and a compensating optical element. The actuatable optical element is provided to receive an optical beam having a plurality of spatially separated wavelength components and diffract the plurality of wavelength components in a wavelength dependent manner. The compensating optical element directs the optical beam to the actuatable optical element. The compensating optical element compensates for the wavelength dependent manner in which the wavelength components are diffracted by the actuatable optical element.
