Perforation rollers for Aluminium

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…..

• The mesh visor is made of galvanized wire cloth • From the outside the mesh visor is covered with aluminised fabric • It shields the face against radiant heat • The mesh visor has a window opening for lenses with the dimensions 60 x 120mm • Among others, blue inspection glasses, green welding glasses, or clear glasses can be utilized in the window opening • The lenses are securely clamped in the lens frame by two steel springs • Like the other face shields, the mesh visors are also attached to an aluminium hard hat bracket (e.g. GFKHH003) • The blackened inner side ensures good visibility and prevents the wearer from being blinded by glare

LT Ultra has also implemented the technology of metal-cutting microstructuring in roller lathes. We can offer the production of structures in a grid between 5 and 150 µm in optical quality for provided rollers.Offer up to a length of 2500 mm, a diameter of up to 800 mm and a maximum weight of 2500 kg.
