The OTX.5 series optical translators are an OEM version of our popular OT.5 series. These compact optical translators incorporate crossed roller bearings for zero crosstalk between X & Y axis adjustments. Precision rolled 100TPI adjustment screws enable submicron adjustment across the full travel of the X & Y axes, with a smooth feel to the adjustment. Foil locks on all axes have been tested to 4g's to maintain adjustment in challenging environments. The Z-axis on the OTX.5-3 uses an internal 80 pitch thread. The drive knob for the Z-axis has six locking screws and six capstan drive holes that maximize accessibility in any orientation.
