Siskiyou’s OT series of optic translators use color coded Soft Touch knob caps in both non-lockable and lockable versions. These knob caps are comfortable to use and provide quick axis location in low light conditions.80-pitch screws are the basis for smooth accurate positioning of all models from the smallest mount to the largest. To meet the demands of many different applications we have XY, XYZ and 5-axis OT series optic translators in three sizes. Te entire OT series comes standard with Delrin® retaining rings and a separate optic adapter. The new OTX series is an even more robust OEM version of the OT translators. The OTX series has been designed to absorb a 4G jolt without moving more than 5 microns. Locks on all axes make them perfect for applications where any misalignment during shipping cannot be tolerated.
