Machine Tools
As a distributor in Japan of EXCEL PRECISION (USA EXCEL PRECISION CO., LTD), we deal with laser interferometer equipment. Combining a dual frequency He - Ne laser system employing stabilized Zeeman and an optical heterodyne detection / signal processor, it is possible to do highly accurate and reliable measurement of a minimum reading resolution of 0.3 nano, and further a low cost system construction. Excel Precision Co., Ltd. has designed and manufactured originally, and established itself as a specialist of laser interference measuring instruments.  More than 5000 units have been used worldwide.
We manufacture not only standard products but also custom-made systems according to customer's request.
Third choice. Excel Precision Laser Interferometer
If you have a laser interferometer from Excel Precision, you can check accuracy at the nano level.
