Meniscus Lenses

Knight Optical can offer Precision Grade Aspheric Lenses for use within Optical Systems. We supply a range of Precision Grade Aspheric lenses for a range of applications – all individually QA checked, and metrology tested for quality to ensure parts meet customer specification. What’s more, our Precision Grade Aspheric Lenses are supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to numerous customers with optical systems. Aspheric lenses are used to correct spherical aberrations and can be as effective as a multi-lens system while taking up less physical space; therefore, reducing weight and cost. As such, these lenses are often used in military applications, such as night-vision goggles or missile guidance systems Please read PDF for more Information ….

Knight Optical can offer Cube Beamsplitters for use within the Scientific Industry. We supply a range of Cube Beamsplitters 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 scientific industry for use as components within spectrophotometers and interferometer. For interferometry, beamsplitters are used to separate light into two beams to compare a reference against a sample. Cube beamsplitters offer some advantages over plate beamsplitters in that they don’t suffer from ghost images and are easier to mount. For more information read PDF…

Knight Optical can supply you with custom made Diamond turned aspheric lenses for use within autonomous vehicle LiDAR systems. Autonomous vehicle LiDAR systems create driverless cars. Whereby the system produce autonomous vehicles which can perform complex manoeuvers and drive in public with little or no input from a user. Spherical aberration occurs in common singlet lenses, which results in an image that appears distorted, aspheric lenses correct spherical aberration. An aspheric lens surface is designed non-spherical, which allows a single component lens to collimate or focus highly divergent rays potentially replacing a multi-lens system. This in turn provides the LiDAR system with a better signal quality, at lower costs whilst making the system more compact. Knight Optical offers diamond turned aspherics from a range of suitable NIR materials for autonomous vehicle LiDAR including N-BK7 or equivalent, sapphire, quartz, UV fused silica, amongst others.

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…
