    • A laser system and interferometer are disclosed comprising a laser source for generating a laser beam, and first and second adjustable elements wherein the first and second adjustable elements have limited rotational motion so rotation of the first adjustable element causes deviation of a laser beam in one plane and rotation of the second adjustable element causes deviation in a second plane, and a laser beam from the laser source is oblique to a required beam direction whereby rotation of the adjustable elements deviates the laser beam enabling alignment of the laser beam to the required beam direction. The adjustable elements may be rotatable through 90°. The first and second planes may be perpendicular to the required beam direction and to each other. At least one mirror may be provided which can be angularly offset to the required beam direction.
    • 公开了一种激光系统和干涉仪,其包括用于产生激光束的激光源,以及第一和第二可调节元件,其中第一和第二可调节元件具有有限的旋转运动,因此第一可调元件的旋转导致激光束在一个平面中的偏离 并且第二可调节元件的旋转引起第二平面中的偏差,并且来自激光源的激光束倾斜于所需的光束方向,由此可调节元件的旋转使激光束偏移,使激光束能够对准所需的光束方向 。 可调元件可以旋转90°。 第一和第二平面可以垂直于所需的波束方向和彼此。 可以提供至少一个可以成角度地偏移到所需波束方向的反射镜。
