The Davidson Optronics D614-104 Penta Prism is also known as an Optical Square. The BK-7 Penta Prism takes the incoming collimated beam ( which may be out of its normal plane by as much as 5 degrees) and re-orients it accurately by 90 degrees. Davidson guarantees an accuracy of +/- 3 arc seconds on these Optical Squares, this one far surpasses that at -0.2 arc seconds. I also have one that has its accuracy listed on the Davidson label as being +0.6 arc seconds. It has lapped pads to precisely mount it or can be used with the threaded post to mount in a spindle. This model of the D-614 has a larger aperture- 1-3/4" X 1-7/8"- for applications that need it. In excellent condition and in their factory mahogany box.
