Tessellated Arrays

Precision Tessellated Mirror Arrays for Advanced Optical & Astronomical Systems

Custom Segmented Mirror Arrays for Astronomy, Research & High-Performance Optics

DOTI specializes in the design and manufacturing of tessellated mirror arrays and segmented optical systems, ranging from small, simple configurations to large, complex assemblies for astronomical, scientific, and high-performance optical applications. Our expertise in precision optical fabrication and polishing has made us a trusted partner and sole source supplier for multiple advanced projects.

We are recognized for delivering:

  • High-accuracy polished mirror surfaces for optimal optical performance
  • Precision machining of multi-hole mounting patterns and complex geometries
  • Reliable production with the ability to meet strict delivery schedules

DOTI currently supports the VERITAS Collaboration at the Fred Lawrence Whipple Observatory by providing mirror refurbishment and optical coating services. These efforts help extend the lifecycle and performance of gamma-ray telescope mirror arrays, supporting ongoing research under the Smithsonian Astrophysical Observatory.

In addition, DOTI has manufactured and supplied precision optical mirrors and tessellated array components for gamma-ray and astrophysics research at leading institutions, including University of Chicago, Case Western Reserve University, and University of California, Riverside.
