The 5201, 5204, and 5208 T-slotted base plates provide the basic building blocks for an alignment telescope base.  Each of these base plates have two parallel T-slots which provide mounting channels for our 5192 adjustable cone assembly.  The cone assemblies permit the optical axis of any alignment telescope to be precisely adjusted in a variety of ways (shift left-right or up-down, as well as pitch and yaw).  Each baseplate in the 5200 Series has three counterbored holes which may be used for customer-supplied mounting.  The counterbored bolt hole pattern also fits the discontinued K+E style collimator test stand, model 7010.

See also related product 5191, which is a similar T-slotted base plate having a 3½" x 8 threaded hole in the center for mounting directly to a stand or any accessory having a matching external thread.
