Kohzu Precision

What Kohzu Precision does

Kohzu Precision Co., Ltd. is a privately held Japanese manufacturer of high-precision positioning and optical measurement equipment, founded in 1945 as a surveying instrument repair shop and incorporated in its current form in 1957. The company designs and produces motorized and manual positioning stages (X/XY, Z, rotation, swivel), low-profile alignment stages, vacuum-compatible stages, compact 6-axis manipulators (MPS/SMR/USM series), double crystal X-ray monochromators for synchrotron beamlines, non-contact wafer surface profile measurement systems (Dyvoce series), and CIPA-standard vibration simulators for camera testing. Its KOSMOS line of motor controllers and drivers integrates the hardware portfolio. Technical differentiation rests on sub-micron and angle-second positioning accuracy, with a demonstrated TX-DCM pitching stability of 17.15 nrad RMS that is world-class for next-generation synchrotron facilities such as NanoTerasu.

The company operates a direct B2B sales model (phone, FAX, inquiry form — no e-commerce) primarily serving semiconductor manufacturers (wafer and camera module alignment), national synchrotron radiation laboratories (SPring-8, APS, ESRF, NSLS, Tohoku University SRIS, PhoSIC for NanoTerasu), camera OEMs (image stabilization testing), and LCD/automotive lamp producers. Revenue is generated through catalog hardware sales, custom OEM projects, and aftermarket overhaul/repair services with a 10-year post-discontinuation repair commitment. Go-to-market combines a domestic Japan direct sales force with a global network of 14 overseas agents covering North America, China, Taiwan, Southeast Asia, Europe, Oceania, Korea, Vietnam, and Israel, supplemented by a Shanghai sales office. Recent strategic activity has emphasized synchrotron research collaborations and incremental product launches in semiconductor wafer handling.
