Diffraction Grating Mount, 25 mm, 3-axis

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.
