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…..
