Thin Film

An IS09001:2008 & British Standard Kitemark company


Helia are constantly looking at global developments in photonics devices & ensuring that processes are in place to address these ever-demanding requirements.

Active areas of internal research & development include:

  • Lifetime enhancing anti-reflection (AR) coatings for GaN lasers
  • Lifetime enhancing OC coatings for AlGaAs lasers
  • Ultra-broadband anti-reflection (AR) coatings for long wave infrared quantum cascade lasers (LWIR QCLs)
  • Tight-edge dichroic filters for Silicon detectors
  • Ion Beam Sputtering (IBS) & Atomic Layer Deposition (ALD) for photonics devices
  • Low energy deposition for organic devices

To span the spectral requirements & encompass the material systems involved Helia employ several different optical coating technologies.

Helia Photonics are active in development & research with organisations such as the Technology Strategy Board (TSB), The Scottish University Physics Alliance (SUPA) & the Small Companies Innovation Scheme.
