Infrared Materials

optical components for molecular laserKnight Optical offers an extensive range of infrared optical materials, specifically designed for use in a variety of laser applications. From molecular lasers to testing and measurement systems such as LiDAR, our expertise in developing custom infrared optical components has become world-renowned.

There is nothing more important than precision compliance when it comes to our customers’ specifications. With laser applications heavily depended upon across the engineering, manufacturing, scientific, medical and defence sectors, it is crucial that the infrared optical components that power them strictly conform across all parameters.

Our extensive range of infrared materials for laser applications includes:

  • Polished blanks
  • Windows
  • Lenses
  • Aspheric types
  • Prisms
  • Rods​

Infrared Optical Coatings

At Knight Optical our technical experts work closely with our customers to optimise their infrared optical components so that they deliver to the highest grade, and also to ensure they are able to withstand the harsh environmental elements that they are so often exposed to.
From anti-reflective coatings designed to improve transmission over custom wavelength bands and multi-wavelengths through to hard coatings such as diamond-like carbon which offers exceptional robustness, corrosion resistance and insulation properties, our capabilities when it comes to ensuring the integrity of your infrared optics are highly sophisticated.

Customisation for Tailored Quality

The entire range of Knight Optical infrared components can be fully tailored to suit specific requirements. Dimensions, focal lengths and tolerances are all customisable and our technical specialists are on hand to provide the guidance you need to make the right choices.

A comprehensive range of substrate materials is also offered, allowing customers to choose the most appropriate materials to suit their individual applications and environmental challenges. Some of the most popular materials we use to create our infrared optical components include:

  • Sapphire
  • Germanium
  • Magnesium fluoride
  • Calcium fluoride
  • Silicon
  • Quartz
  • Polycarbonate
  • Fused Silica
