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是一种可调的铝衍射光栅，设计用于容纳25毫米高的方形或矩形光栅。这一专利未决的安装包含了一个运动学设计，它不仅允许俯仰和偏航，还包括光栅线定向的滚转。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。除了衍射光栅外，这个底座还可以容纳1英寸的分束立方体、直角棱镜和方形镜子。DGA-25上的所有3个调整器都有100 tpi线程，用于特殊的对齐灵敏度，并且是可锁定的。旋钮提供5/64英寸的访问权限。(2毫米)旋钮后面的六角键。
