  • Parallelism of > 2 arc seconds
  • Scratch and Dig of 10-5
  • Modification of supplied substrates
  • Custom fabrication and free engineering services
  • Anti-reflective coatings including TiO2, BBAR, MgF2, and custom coatings

Our λ/10 optical flats are manufactured from synthetic fused silica which provides the following:

  • A high degree of purity
  • Superior environmental durability
  • A low coefficient of thermal expansion
  • Outstanding resistance to thermal shock
  • Excellent transmission from the UV to the NIR
  • Exceptional hardness for demanding applications requiring a high degree of flatness

Due to the above characteristics, fused silica flats are used in many industries including, aerospace, astronomy, military and commercial avionics, medical and scientific instrumentation, academics and research, and industrial applications. In addition, they are an excellent choice for laser applications, spectroscopy, photolithography, vacuum windows, and many other numerous applications.
