Rod Lenses for Optical Systems

Medical Sensors are used for the detection of enzymes, proteins, blood, bacteria & other substances inside the human body so that the correct treatment can be administered should abnormalities occur. These sensors use a number of different Interference Bandpass Filters of different wavelengths dependent on what needs to be detected. With our wide range of stock filters, Knight Optical provide wavelengths from the UV at 214nm for detection of bloods into IR wavelengths of 2000nm for the detection radiation or gases. These interference filters are also available for full customisation to your specific requirement. They are mounted in an aluminium ring making it easier for integration, we can also provide filter wheels to ensure quick changing within the instrument.

Knight Optical can offer Flashed Opal Diffusers for use within Photography. We supply a range of Flashed Opal Diffusers 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 within photography and entertainment industries. Flashed Opal Diffusers alter the divergence of incident light. Opal diffusers are typically used in to diffuse the flash from cameras to prevent photos with harsh light and hard shadows to soften and improve the appeal of the image. Also used in traditional imaging techniques for the control of illumination. Opal diffusers are coated with For more information read PDF …..

Knight Optical can offer Meniscus Lenses for use within Optical Systems. We supply a range of Meniscus 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 with Optical systems. Any spherical surface will introduce spherical aberrations to an optical system. Meniscus lenses are designed with the curvatures of the lens in mind to minimise these spherical aberrations. This effect is more noticeable with higher index glasses as spherical aberrations increase with the change in index. Meniscus lenses can be an effective compromise on cost and aberration when compared to using aspheric lenses or multiple lens. Fore more information read the PDF….
