About Us

Sheaumann is a U.S. manufacturer of semiconductor laser diodes providing innovative, high quality solutions for demanding projects in the near-infrared wavelength range. Our custom packages are tailored to your specifications and are available in low minimum quantities. We also offer cost-effective solutions for large-scale production. Our 18,000 square foot cleanroom houses all activities under one roof, from wafer growth to test and reliability. Additionally, we have 6,000 square feet of dedicated space for military projects in order to ensure the appropriate security.  Our quality management system has achieved ISO 9001:2015 certification and CMMC readiness Level 3 for NIST SP 800-171, FAR 52.204-21 and DFARS 252.204-7012 compliance. Our products also comply with RoHS 3 and REACH requirements.

Our class 1000 and class 10,000 cleanrooms are the perfect place to manufacture your next project. 

We’ve Got Engineering Chops.

You’ve Got Options.

Our in-house wafer growth, processing, and packaging capabilities allow us to provide custom solutions for demanding projects of any size. By manipulating some of the many fabrication processes on even a molecular level, we can tailor laser diode characteristics for optimal performance within your system. Since each wafer yields thousands of laser diode chips, we can easily scale up to large production once your project takes off.
