The DGA-25 is an adjustable aluminum diffraction grating mount designed to hold square or rectangular gratings that are 25 mm in height . This patent pending mount incorporates a kinematic design that allows not only pitch and yaw but includes roll for orienting of the grating lines. The DGA-25 has the CenterPoint™ post mounting feature which places the surface of a 6-mm thick diffraction grating in line with the axis of rotation of the mounting post.  In addition to diffraction gratings, this mount can hold 1” beam splitting cubes, right angle prisms, and square mirrors.  All three adjusters on the DGA-25 have 100-TPI threads for exceptional alignment sensitivity and are lockable. The knobs provide access to 5/64-in. (2-mm) hex keys in the rear of the knob.


DGA-25是一种可调节的铝衍射光栅支架，设计用于支撑25毫米高的方形或矩形光栅。该专利悬架采用了一种运动学设计，不仅允许俯仰和偏航，还包括用于光栅线定向的轧辊。DGA-25有中心™后安装功能,地方6毫米厚的表面衍射光栅与转动轴的安装。除了衍射光栅，这个安装可以容纳1“分束立方体，直角棱镜，和方形镜子。DGA-25上的所有三个调整器都有100-TPI螺纹，具有非常高的对准灵敏度，并且可以锁定。旋钮提供5/64英寸的访问权限。(2毫米)六角键在旋钮的后面。
