Knight Optical’s Silicon Diamond Turned Aspheric Lenses for the Defence Sector
07 Apr 2021
A firm favourite component for the defence sector, our Silicon Diamond Turned Aspheric Lenses are widely used across the discerning industry. These premium-quality lenses are commonly used for the detection of sources radiating at a black body temperature of 700K; such as the muzzle flash from sniper rifles and mortar pieces.
Due to its lighter weight and more robust characteristics – when compared to Germanium – Silicon is often specified for a variety of uses within the defence sector. Alongside these two prime benefits, Silicon Diamond Turned Aspheric Lenses also boast another desired feature. Due to its ability to correct spherical aberrations, they can be as effective as a multi-lens system while taking up less physical space and reducing both weight and cost. And it's not only the defence industry that's relying on Silicon's reliability; the photonics sector is also a regular specifier of the sought-after component.
Here at Knight Optical, we understand the importance of ultra-precision and the need for tailor-made solutions; particularly for industries such as the defence sector. It's for this reason that we offer our Silicon Diamond Turned Aspheric Lenses as custom-made components. Providing seamless integration with any device – regardless of size or requirements – this made-to-measure service allows you to specify the dimensions, substrates, tolerances and optical coatings – if required – that are best suited to your application.
