Photonics & Precision Optics

Plasma Quest Limited can deposit high-quality materials for use in photonics and precision optics.   The HiTUS deposition system has demonstrated the ability to produce optical filters and waveguide materials at very high deposition rates, while offering significant advantages over alternative technologies.

A wide range of dielectric films can be reactively sputtered at high rates for use as a waveguide material.

Material imperfections can cause absorption, radiation and scattering resulting in beam propagation loss in photonic and precision optic devices. PQL’s differentiator is the independent control of the plasma ion density and the ion energy enabling an unparalleled range of deposition variables.  This enables the deposition of high-quality thin films which are

  • smooth
  • uniform
  • stress controlled
  • have very little argon inclusion (<1%)
  • refractive indices close to bulk

The HiTUS technology also has the ability to control the growth mechanism of the material, ranging from amorphous to crystalline and also directing the preferred crystalline direction.

If a material can be sputter deposited, it can be coated using the Plasma Quest approach. Please Contact Us for a discussion about how our coating service can solve your problems. We look forward to speaking with you.


If you would like to discuss your trial requirements, obtain costing, turnaround times, or for any other questions, we would love to hear from you.
