Passing filters - Import export

CMOS sensors are used within commercial grade Digital SLR cameras as a replacement for the more expensive CCD. These CMOS sensors are extremely sensitive to IR light, which can lead to discolouration. IR cut filters are used to block the IR light, meaning that photographs are taken with life-like colours. Colour Glass Filters can be used in variations of Bandpass, Long pass and Short pass, depending on which wavelengths of light need to be blocked resulting in different key areas being more easily distinguished. Knight Optical offers Colour Glass and IR cut filters for such an application, with a wide range of band widths and cut on/off wavelengths. As above these are available as Bandpass, Long pass or Short pass filters and we can also offer customised filters with coatings specific to the wavelength of your choice. We hold a massive inventory of IR cut, Bandpass, Long Pass and Short Pass filters: Read PDF for more info….

Knight Optical can offer you Stock and Custom Colour Glass Filters, for use within Inline Cameras in a range of materials of brands such as Schott, Kopp and CDGM. Depending on the achievable wavelength and desired affect you need for the Inline Camera we can find a suitable material for your application. Colour Glass Filters are good for selecting a particular wavelength to be absorbed so that the high out of band blocking in achieved. With regards to the use in Inline Cameras, Colour Glass Short pass Filters are more desirable as they cut out the IR wavelengths mean the imaging is not saturated with the IR giving the image better clarity. Colour Glass Filters are polished sheets of special glass that have been cast with a dye. Colour Glass Filters generally are relatively cheap and very stable. The disadvantage with them is that they are only available in a relatively small number of variants, and so can be restrictive in shortwave selection.  For More Info see PDF...

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…..

Automatic Number Place Recognition Cameras otherwise known as ANPRs; are camera devices designed to work at certain wavelengths (dependent on Country) to read a license plate’s number of a vehicle to then track it through a database to identify any criminal offences links to that car, such as uninsured; stolen; major and organised crime; and even terrorism. They are typically installed on motorways; busy roads around cities and towns; and also on police cars as well as specialised ANPR police vans. Knight Optical offers Colour Glass Filters for such an application, be it either long pass or bandpass filters.

Plastic materials may crack under the prolonged exposure to a UV light source… But not Knight Optical’s Dichroic Hot Mirrors! Knight Optical can supply you with high quality and cost effective Dichroic Hot Mirrors for use in optical systems where unwanted UV or IR light negatively impacts on the system quality. This includes UV and IR Sensitive Systems, medical illumination and display fibre optics. Prolonged exposure to UV light can cause degradation in plastic materials resulting in cracking and, eventually, mechanical failure. Exposure to IR can cause undesired thermal energy and heat into the system that can damage delicate components. Dichroic hot mirrors solve this issue by reflecting UV and IR light away from the component, meaning cost We hold a massive inventory of Bandpass, Long pass, Short pass, Band-blocking and Colour-correction filters.

THE EFFECT Diesel fuel contains paraffin which promotes clean combustion and lubricates the fuel system components. At low temperatures, however, paraffin forms crystals. As the temperature falls, more and more crystals form and coalesce into lumps which then block the fuel lines and fuel filter. The active components in ERC Diesel Anti-Freeze „enclose“ the crystals, thus them from growing and coalescing with other crystals. In addition, ERC Diesel Anti-Freeze forms crystallization nuclei which encourage the formation of large numbers of small crystals that can then easily pass through the fuel filter. THE RESULT - Prevents the formation of large paraffin crystals - Enhances the reliability of diesel-engined vehicles in winter - Lowers the CFPP* as far -33°C (depending on the quality of the diesel fuel used) THE ADVANTAGES AT A GLANCE - Keeps paraffin crystals small enough to pass through the fuel filter - Improves the low-temperature characteristics of all diesel fuels

The system RS 6000 is a high-performing recycling system that cleans large oil volumes in several process stages. This system was constructed for many years of reliable work without service. By several process steps such as heating and settling, large amounts of water and dirt are removed. Additionally, the usage of settling technology and a pre-filter increases the service life of the main filter. The RS 6000 can be operated manually, semi- automatic, and fully automatic. It is the ideal recycling system for central treatment of, for example, cutting oil or cooling lubricants. 400 V asynchronous-motor Robust, stable gear pump Free choice of settling- and heating times and the number of filter passes Either manual, semi-automatic, or fully automatic operation Displays for operation- and process status Flow regulation for high viscosity oils Element lifter for fast filter exchange

Biological exhaust air cleaning is used whenever exhaust air has to be cleaned from volatile organic compounds (VOCs) and odours. Biofilters play a major role in this process. The polluted exhaust air is passed through a filter medium where the VOCs and odours are separated. Normally, this medium is an organic carrier material where microorganisms are grown on. They convert the VOCs and odours into noncritical components by means of their metabolism. Especially regarding the removal of odorous substances, biofilters are a very efficient and comparatively inexpensive way of biofiltration with an efficiency of up to 99 %. BIOCATbiofilters have a high degree of efficiency in a wide range of applications, even for exhaust air components that are difficult to dissolve in water.

An engine oil pressure switch is used to maintain power to the engine, and the vehicle, once the engine has started. When the engine is cranking, power is being supplied through the starter circuits. However, once the engine is running, and the oil pressure is up, power is routed through the oil pressure switch and sensor unit. This is done to ensure the engine is not run without oil. If the sensor does not read the right pressure, the switch will not close, and the vehicle will not stay running. The pressure switch is generally place or fitted around the Engine Oil filter as the oil line has to pass through the filter to be filtered during its continuos cycle of use.

Filters play a vital role in heating, ventilation and air conditioning systems within the ducting. When airborne pollutants enter the duct they pass through the the filter which allows for the air to continue to pass through but traps the microscopic particles and does not allow them to pass back into the the building when the air is recycled.

EFKC filtered shelter fans are used to supply fresh air. It can be used in two different positions thanks to the by-pass cell. Normally, the air is sent indoors only by passing through the G4 Filter. When we want the air to be cleaned, it is passed through the G4 cassette filter, active carbon cassette filter and M6 cassette filter, which is more sensitive than the coarse filter, and sent indoors. By-pass air dams are made with a sliding system.

Our BlueClean® HC PRO range of horizontally mounted cartridges are designed with maintenance and ease of use in mind.
