Abstract
该新型光束偏转器属于激光新器件。其中光束偏转元件是由两块完全相同的直角光楔构成的“空气棱镜”。顶角连续可变，主截面可连续旋转。出射光束的方向可以在60°圆锥角范围内任意改变。与外国已有的类似器件相比，其特征在于消除了光束偏转过程中的附加平移效应。理想地满足单纯的小角度调节或扫描。该新型在复杂的现代光学实验光路中，尤其在大型设备系统整体光路的统调中，发挥了高效率高精度的作用，是一种用途很广泛的通用型器件。The new beam deflector is a new laser device. The beam deflection element is an "air prism" composed of two identical right-angled optical wedges. The top angle is continuously variable, and the main section can be continuously rotated. The direction of the outgoing beam can be changed arbitrarily within the range of 60°cone angle. Compared with the existing similar devices in foreign countries, it is characterized in that the additional translation effect in the beam deflection process is eliminated. Ideal for simple small angle adjustments or scanning. This new type plays a role of high efficiency and high precision in the complex optical path of modern optical experiments, especially in the overall adjustment of the overall optical path of large-scale equipment systems, and is a general-purpose device with a wide range of uses.
Description
The utility model belongs to laser new unit technical field.
In the modern optical experiment light path of complexity, often contain a plurality of large-scale separate units.The monochromator of for example large-scale gas or solid state laser, pump light source laser-dye laser system, the experimental subjects device that has heating, low temperature or vacuum system, terminal or other large-scale analysis and detecting instrument etc., owing to being not easy to or can not moving their optical axis neatly, make the tracking of whole light path very difficult.So far, general situation is or the leg bolt of using system excessively, or utilizes any utilizable implements (comprising books) pad temporarily on hand.Obviously light path is difficult to be operated in optimum state.Its consequence is to have caused artificial instability.In some laser application project and the laser on-line detecting system similar problem is arranged also.
For above-mentioned object, reasonable plan should be that the suitable optical axis that gathers large scale system is removed in the orientation that utilizes " optics joint " to change light beam.Generally speaking, the orientation of light beam is regulated and can be decomposed into traversing and deflection two big classes.About beam deflection, existing similar functions device, a kind of is to be made of rotating reflector group.Owing to structural limitation, be not suitable for the requirement of small angle deflection in the above-mentioned object.Another kind is a refractive, and two wedges that dioptric power is identical, its right angle face stick together mutually and vertical with incident light axis (Fig. 1 a).When their respectively or jointly when incident light axis rotates, two wedges are to the combination of beam deflection effect, can make transmitted light beam change direction arbitrarily in a limited cone angle scope.But there is the shortcoming of an essence in the beam deflector of this structure, and promptly when it was operated near 0 ° of deflection, the structure of device was brought an additional lateral displacement (Fig. 1 b) to transmitted light beam.And this additional translation effect can give the tracking of large complicated light path mentioned above or near other work that need do low-angle conversion or scanning 0 ° makes troubles and difficulty.Perhaps can not use.
This novel purpose is for overcoming the above-mentioned shortcoming that existing device exists, providing a kind of novel beam deflection device of eliminating additional translation effect.
This novel subject matter is as follows:
The one, utilize the right angle wedge of two identical drift angles for α, (Fig. 2 a) forms one " air prism " to the relatively coaxial placement in inclined-plane.As light deflection element.
Two is that two right angle wedges can be distinguished independently and place along a helical trajectory around the main shaft of this device, thereby makes the drift angle of " air prism " change (Fig. 2 b) continuously from 0 ° to 2 α.Simultaneously, two wedges can be placed integratedly, and promptly the main cross section of " air prism " rotates around incident light axis.Two kinds of rotations are combined, can make outgoing beam directed arbitrarily in a limited angulus pyramidis that with the incident beam is axle.More than two kinds of rotations realize by the mechanical structure that is shown in Fig. 3.
This is novel provide as the structure described in the above-mentioned novel main points, compare with external existing similar device, the configuration of two right angle wedges is opposite (seeing Fig. 1 and reference 1) just.This difference causes the difference of optical property essence.In this was novel, two effects of right angle wedge in light path were constantly equal to the parallel plate glass that an air prism is contained in an inside of vertically inserting light path.Thereby do not cause additional light beam traversing (seeing Fig. 2 b).Two wedges rotate relatively along spiral trajectory, can guarantee in position, any angle (0 °-2 α), and " air prism " do not contain " air parallel flat " composition of equivalence, and keep a top rib width to approach zero thin air prism.This has just further eliminated additional translation effect.Thereby this novel device that provides can satisfy ideally near 0 ° does the little simple angular adjustment or the requirement of scanning to light beam.
The structure of the beam deflector embodiment that the scheme of this novel proposition of foundation is finished is shown in Fig. 3, and the technical indicator that is reached is as follows:
Service band 430-700 millimicron, 515 millimicrons of centre wavelengths
