About Armstrong Optical Ltd


Armstrong Optical Ltd was founded in 1997 with the remit of introducing the FISBA OPTIK phase shifting interferometry systems to the UK with complementary optical metrology products and interferometry accessories. The product range has now been expanded to include:

Optical metrology systems:
  • visible and infrared interferometers for evaluating and measuring optical surfaces and wavefronts
  • phase shift add-on kits and software for all makes of interferometer
  • interferometers for measuring distance and thickness to nanometer resolution
  • interferometers for fibre-optic applications and measurement
  • non-contact vibrometers
  • optical manufacturing alignment, cementing, assembly & inspection systems
  • automated optical test stations
  • autocollimators, goniometers, spherometers and centration instruments
  • centre thickness measurement systems
  • transmission flats/spheres and aperture converters for all makes of interferometers
  • fringe analysis software
  • non-contact 3D surface form, roughness and thickness analysis & surface mapping systems
  • interferometric systems for dynamic MEMS analysis
  • thermal imaging & thermography cameras & sensor modules
  • scanner and camera test charts, MTF test patterns and targets
  • custom test patterns and photolithographic service
  • multi-channel, self calibrating high speed streak camera systems

    Optical assemblies & components
  • spherical and aspheric lenses for all wavebands
  • microlens arrays and diffraction gratings
  • plano components - mirrors, prisms, windows
  • non-rotationally symmetric (free form) aspheric components
  • complete, tested optical and optomechanical assemblies
  • micro-optical components and complete imaging assemblies
  • standard and customised optical coatings
  • diffractive optical elements for abberration correction

    We are happy to offer custom solutions to specific requirements and welcome as much dialogue with our customers as possible.

    The current "front of house" Armstrong team comprises Ian Routledge, specialising in all matters interferometric; Ian Johnstone, handling the thermal imaging camera range and non-contact surface profiling; Rob Roach, managing the optical component/microlens ranges and Angie Routledge, keeping us all under control and supervising the office and marketing operation.
