Uv filters - Import export

Unwanted hair, be gone! Knight Optical offer a range of Stock Dichroic Filters, for use within IPL Applications. Intense Pulsed Light filters are essential to IPL applicators as they are used to filter out the UV wavelength range; and transmit between 400-1200nm for use within cosmetic lasers that are designed to remove unwanted hair, vascular treatment and even acne treatment. These IPL Filters are often stacked between sapphire windows within the IPL applicator to offer a more defined wavelength spectrum when in use. Dichroic filters consist of thin film dielectric coatings on glass, and are designed to offer high transmission over a specific wavelength while reflecting all other wavelengths, having negligible absorption. The dielectric coating is perfect for high power applications, and does not show the strong fluorescence of certain glass filters. We hold a massive inventory of Bandpass, Long pass, Short pass, Band-blocking and Colour-correction filters.

Intense Pulsed Light Systems use not only use filters, that are used to filter out the UV wavelength range; and transmit between 400-1200nm for use within cosmetic lasers that are designed to remove unwanted hair, vascular treatment and even acne treatment. But they also use Homogenizing Rods to help evenly distribute light. The Light source will enter a light pipe at a variety of incident angles, which is designed to utilise its total internal reflection to channel the light from the entrance of the light pipe to the exit. The material’s refractive index is the only factor which affects the light pipes critical angle; this defines the angle of acceptance which the total internal reflection will occur at. All our Homogenizing Rods are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, using our Trioptic’s PrismMaster, and Starrett AV300 Video Imaging System..

Knight Optical can offer IR-cut filters for use in Heat Shielding. We supply a range of Custom and Stock IR-cut 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 with Heat Shielding requirements. Our IR-cut filters allow good transmission levels of visible light but cut off IR and UV radiation. Our precision grade filters have an AR coating to increase their visible transmission. In many systems that require heat shielding while still needing visibility an IR-cut filter can be used. These can attenuate infrared radiation and allow through visible light, allows your temperature sensitive equipment For more information read the PDF……

We offer a state-of-the-art contract chemical blending facility comprising four five-tonne bespoke vessels that have been designed especially for us. Some of the vessels are mounted on load cells for increased accuracy and all are controlled from a fully-automated PLC control panel. The liquid blending tanks have been constructed from food grade 316 stainless steel and are fitted with fully-automated cleaning in place (CIP) regimes for hygiene purposes. Two of the vessels in situ have the unique capability of handling exothermic chemical reactions with inline plate heat exchangers and temperature control systems. These vessels are also fitted with direct acid and base feeds to minimise exposure of the liquid blending personnel. The chemical blending tanks can be fed by a double filtered UV treated mains water feed system, or alternatively, from a full deionised water plant complete with reverse osmosis that is generating water to a pharmaceutical specification.
