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.
