Energy & Utilities

Suffice to say; the Energy & Utilities markets are widespread and highly exposed the world over. There is, however, less frequent publicity surrounding the components that augment the efficiency and inch-perfect precision behind the functioning processes within these sectors.

Unbeknownst to some, optical components are a vital cog in the wheel for numerous applications within these industries and feature in essential mechanisms used for functions such as:

  • Oil drilling and recovery
  • Oil in water analysis
  • Gas detection
  • Gas analysers
  • Photovoltaics/solar
  • Telecommunications
  • Fibre optics used for electricity distribution
  • Wind turbines
  • Pyranometers
  • Drones
  • Hydroelectricity
  • Solid-state lighting
  • Emission testing.

We have a considerable customer base across the sector and as a long-term partner with many spearheads within the field, our optical components are regularly specified for large- and small-scale applications. We have witnessed six categories prevailing within the Energy & Utilities sectors, which include:

Gas analysis

Highly reliable procedures are imperative in gas analysis and opting for the right components to meet your requirements is critical for operational processes. Harsh environments and hazardous substances mean your analysers need to survive under pressure for safe and effective functionality. Opting for the highest quality components domineers here and ensuring you reinforce your specification with the correct coatings is equally essential. We have a range of custom project-specific coatings and materials available to accurately match the requirements sought by your application.

Oil drilling & recovery

Here, camera systems play a crucial role in enabling drilling rigs to enhance safety, control and ensure optimal operation with real-time footage. Oil drilling and recovery are incredibly perilous and require high-level surveillance to safeguard personnel and the environment. Hard-wearing protection is necessary for a task of such exposure, and it is here that premium quality dictates both precision and longevity. Our sapphire domes are the components of choice for many working within the oil drilling and recovery industry due to their robust formation and long-lasting lifespan.

Gas detection

Our bandpass filters are frequently employed in gas detection applications for their ability to identify many emissions. As different gases emit at various wavelengths, specific bandpass filters permit the identification of each type of gas. For instance, if you are looking to detect carbon monoxide, your wavelength range will be 4.73μm. If you are uncertain on the wavelength required for your application, contact a member of our technical sales team today to discuss your requirements.


In recent years, drones have peaked in popularity within the entertainment industry; however, the oil and gas sector has also found a purpose for UAVs. The use of drones in the industry has taken off in recent years; allowing for safe and efficient maintenance as well as inspections. With drones becoming commonplace within the field, safety amongst personnel is set to improve with UAV monitoring and notifications of hazardous occurrences such as fires and spills. Fundamental and potentially life-saving equipment within such extreme environments requires precision and high-quality materials to ensure reliable performance. Our customised domes are specified for their reliability and resilience in many UAV applications, including drones.
