The OFT optical focus translator allows the user to simply adjust the focus of an optic along the optical axis. The simple cam design is able to translate 0.25-inch in 30° of rotation of the focusing lever. Once in position the OFT can be locked with a Delrin® knob. Adjustment of the Z (focus) axis does not rotate the optical element when the lever is turned. The inner sleeve, in which the optical element is held, does not rotate, so optical axis height is constant and polarization orientation is maintained. Vertical or horizontal mounting of the OFT is made simple with multiple 8-32(M4) and 1/4-20(M6) tapped holes on its diameter and back face. The OFT is compatible with our OH1.0 series of optic holders.
