About Us

Excel Precision Corporation is the leading manufacturer of laser interferometers.

We custom design lasers with high resolution, great accuracy and increased precision to ensure excellence in measurement for Wafer Steppers, and ultra-precision machining and measuring.

The demands for higher precision, faster throughput and increased reliability for laser measurement applications require better lasers. The laser must be uniquely designed for these exacting requirements. Excel Precision, located in Silicon Valley California, has a very strong R&D team. Our experts understand all the parameters that go into custom designing of laser interferometers to ensure excellence in measurement.
