INTRODUCTION

ABOUT

We adapt and evolve with the changing times.

Sanei mainly produces optical jigs that support optical components.
Strict dimensional accuracy is required for spherical machining of cast plates and other optical jigs required for polishing.
In response to these strict requirements, we utilize the technology we have cultivated over many years. We produce products that meet the needs of the times using everything from NC lathes to multi-tasking machines.
At Sanei, we will develop together with the optical industry by responding to their needs, customizing, and producing the jigs and tools that will be needed as the optical industry develops.
