摘要
The invention relates to a device (102) for optical beam expansion of an optical system having a guide tube (220), a first guide cylinder (222) having a first lens (226), wherein the first guide cylinder (202) is arranged within the guide tube (220) so as to be displaceable along the longitudinal axis of the guide tube (220), and a second guide cylinder (224) having a second lens (228), wherein the second guide cylinder (224) is arranged within the guide tube (220) so as to be displaceable along the longitudinal axis of the guide tube (220). A first displacement device is provided to displace the first guide cylinder (222) along the longitudinal axis (340) of the guide tube (220), and a second displacement device is provided to displace the second guide cylinder (224) along the longitudinal axis of the guide tube (220).
