Precision Rhomboid Prisms

Knight Optical can offer Calcium Fluoride Lenses for use within the Oil and Gas Industry. We supply a range of calcium fluoride lenses for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers in the oil and gas industry for use within detectors and spectrophotometers. For spectroscopy, calcium fluoride is superior to many other materials such as N-BK7 or fused quartz due to a lack of OH absorption peaks. Due to calcium fluoride’s low absorption and reflection and high damage threshold these lenses can often be used uncoated and are ideal for use in laser applications as well as thermal imaging systems, spectroscopy and high energy neutron detection.

Knight Optical can offer Toroidal Mirrors for use within Optical Systems. We supply a range of Toroidal Mirrors for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers with Optical Systems. Our Toroidal Mirrors are designed to minimise astigmatism when used in off-axis geometry. They are easier to manufacture than parabolic or ellipsoidal mirrors and therefore can be made much cheap with the same quality. Toroidal mirrors are used for correction of aberration in a range of scientific instrument applications such as spectroscopes monochromators and imaging devices. For more details read PDF…

Here at Knight Optical, we understand that there is no one size fits all for your optical component specifications. That is why – as well as edging down our stock optics – we also offer our entire range as custom-made components. This bespoke option is popular across a variety of sectors such as defence and aerospace, medical and research as well as engineering and manufacturing industries; to name a few. By opting for our customised service, not only will you be able to choose the material, millimetre-perfect dimensions and thicknesses best suited to your application, but you will also be able to pick appropriate optical coatings to protect or enhance your device's operability. If you would like to discuss your optical requirements with a member of our team or to find out more about our custom-made optics, please get in touch on +44 (0)1622 859444, choose option One.

Knight Optical can offer infra-red interference Shortpass filters for use in Heat Shielding. We supply a range of infra-red interference Shortpass filters for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers in Heat Shielding. Infra-red interference Shortpass filters are designed to transmit wavelengths shorter than the “cut-off” of the filter and to block bands above that. In many systems that require heat shielding while still needing visibility a shortpass filter can be used. These can attenuate infrared radiation and allow through visible light, which allows your temperature sensitive equipment to be visible. They can also be paired with a longpass filter to make a bandpass filters. Read PDF for more Information…..
