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. The wavelengths typically used by ANPR camera companies are: 695nm; 740nm; 810nm; 850nm; 910nm and 940nm Read PDF for more information

Knight Optical has successfully launched a range of Stock Colour Glass Filters, for use within Entertainment and Design Industry. Within the LED Lighting Industry, Colour Glass Filters can used as downlights within a stage production by filtering the different visible wavelengths and filter out unwanted light from a white light source to provide desired coloured light that is perceived by an audience to be a highly saturated or intense colour. This is just what you need to help set the atmosphere for whatever event you’re planning We hold a massive inventory of Bandpass, Long pass, Short pass, and Mounted Colour Glass Filters. Stock sizes of 25mm diameter; and 50x50mm squares x 1mmthk with larger sizes of 300x300mm available on most of our filters as a custom option. Custom shapes and sizes at short notice, in most cases turned around within 1-2 week. Alternative thickness substrates available. For more information read the PDF …..

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.

Need to measure the fluorescent properties of a component with your Spectrometer but you feel like something’s missing? Maybe it’s Knight Optical range of Stock Dichroic Filters, ideal for use within Fluorescence Microscopy and Spectroscopy. For Fluorescence Microscopy and Spectroscopy, dichroic filters are used as beam splitters within the microscope system. They are used as an edge filter at a tilted angle of incidence (typically 45°) to direct the illumination of an excitation frequency towards the sample of interest, and then at an analyser to reject the same excitation frequency but passes a particular emission frequency. Dichroic filters offer superior contrast between transmitted and reflected wavelengths; having negligible absorption. Having a dielectric coating they are perfect for high power applications and they do not show the strong fluorescence of certain glass filters. For more information read the PDF

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. Read PDF for more Information….

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….

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 set consists of 7 coloured filters with a diameter of 5 cm each: red, orange, yellow, green, blue, indigo and violet. The filters correspond to the different wavelengths of visible light. The key to well-being is physical, emotional, mental balance and the impact of colours can have a beneficial effect in restoring and maintaining it. Presentation Colours are all around us. They enrich our world in all aspects of life. Colour is light and light is colour. The sun emits light at different frequencies. It is believed that energy is transmitted in waves. The distance between successive waves is called the wavelength, and the number of oscillations of a wave in one second is called the frequency. These frequencies can be separated by a process called white light splitting. As white light passes through a crystal prism, it refracts and splits into the seven colours of the spectrum. Each colour has its own frequency.

Limit values (so called MAK-value) for pollutants in ambient air have been defined by law, which should not be exceeded. This is done with the help of specially coated activated carbon that is amongst others in the activated carbon filter, and removes pollutants from the air of the wearer. But from the first, the breathing air needs to contain at least 19% oxygen! Dependent on application area you can choose between filter types as follows: Type A: colour code: brown Organic vapour or gas with boiling point above 65°C Type AX: colour code: brown Organic vapour or gas with boiling point under 65°C Type B: colour code: grey Inorganic vapour or gas (no CO) Type E: colour code: yellow Sulphur dioxide and acid gases or vapour Type K: colour code: green Ammonia and ammonia derivates Type Hg: colour code: red Mercury vapour Type CO: colour code: black Carbon monoxide Type P: colour code: white Dust Breathing filters, depending on filter type, can remove certain pollutants from...
