Abstract
The invention relates to an arrangement of optical elements in projection systems, preferably in projection modules having a changeable focal width such as for the imaging of tilt mirror matrices or for the imaging of reflective, i.e. transmissive, LCDs, whereby the optical elements () fixed in place in mechanical holders () are arranged so that they can be positioned on a common optical axis () relative to one another. According to the invention, for the purpose of accommodating the mounted optical elements (), a common carrier element () is provided. With a minimized number of optical and mechanical elements, both the construction lengths and the diameters of the overall arrangement are reduced so that inexpensive production is possible.
