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...

Glass Neutral Density filters attenuate light by absorption just like the gelatine neutral density filters. Glass ND Filters are more robust and tend to have more uniform absorption characteristics. They also attenuate by absorption and so care must be taken to avoid overheating. Attenuation is achieved by polishing glass to the correct thickness. Knight Optical offers stock absorptive ND filters in 12.5mm and 25mm diameters, and 50x50mm squares manufactured from high quality glass. Each filter is available with blocking between 0.1 and 4.0 OD and are available to purchase direct from this page. In addition to our stock absorptive glass ND filters, Knight Optical also offers an extensive custom optic service thanks to our many years of experience in the industry. We can supply ND filters cut to sizes and shapes to fit individual application and mount filters where applicable. READ PDF FOR FULL SPECIFICATION

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….

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

UVA Filters: UVA Filters: UVA rays are part of the light spectrum emitted by the sun. These ultraviolet rays, which can cause allergies and aging in the skin, can penetrate the epidermis by passing through clouds and glass. UVA filters are components that help prevent these rays from causing damage to the skin by filtering them. They are used to protect the skin from harmful sun rays and prevent allergies and signs of aging caused by the sun. UVB Filters: UVB Filters: Unlike UVA rays, these ultraviolet rays reach the Earth in smaller quantities and cannot pass through clouds and glass like UVA rays. However, they can penetrate the epidermis. UVB rays can lead to problems ranging from sunburn and excessive tanning to skin cancer with prolonged exposure. UVB filters help reduce the level of exposure to these rays by filtering them. They play a role in preventing damage caused by burning in the skin by supporting the protection of DNA cells.

With high-quality filter tubes and PTFE diaphragms. Paint dust filters Wet painting also results in overspray. Overspray is the solid portion of the paint that is not taken up by the workpiece. According to the purpose of use, the overspray is moist and sticky immediately after release. It is captured by the exhaust air stream in the spray booth and fed to a filter. This can be, for example, a baffle plate filter, paper filter, fleece filter, glass fibre filter or also combinations of these. The adhesive effect causes the paint particles to adhere to the contact surfaces of the respective filter medium, as a result of which a good degree of separation is achieved. However, all these filters are storage filters, i.e. the filters clog up more and more during operation and cannot be regenerated. A filter exchange becomes necessary if the exhaust air rate of the spray booth falls below the minimum. This can be very time-consuming under certain circumstances and the work process must be interrupted in order to do it. To make things worse, not only must the filtered and bound paint residues be disposed of, but also the actual filter materials. Such tooling times are not justifiable for automatic, continuous or multi-layer painting processes. Continuous procedures such as automatically cleaned filters are likewise required for this. The humidity and the adhesiveness of the particles to be filtered are thereby the problem. In order to solve this problem, the paint particles should be relieved of their adhesive capability as far as possible whilst still inside the paint booth. Our patented ‘RTS-Rotation’ system is outstandingly well suited for this. The system is comprised of slowly rotating brush rollers, which take up the adhesive paint particles on the surface of the bristles and allow them to dry there. The bristles are automatically regenerated at pre-specified time intervals by combing devices that swing in at the rear of the brush rollers. The dislodged paint residues can then be removed and disposed of either manually during work breaks or automatically during operation. The degree of separation of this system is, however, insufficient to satisfy the environmental protection requirements concerning residual dust content in the exhaust air. A further filter stage is necessary for that. It must be assumed that the paint particles arriving here are to a certain extent still damp and sticky. For this we use special paint dust filters with high-quality filter tubes with PTFE diaphragms. If necessary, precoating agents (auxiliary dust) are used in order to neutralise the adhesive capability of the particles and to keep the dust layer on the filter elements permeable to air. The precoating agent is injected into the raw air pipe by means of special dosing units. The filter tubes are cleaned by means of compressed air impulse cleaning. The use of this technology requires special know-how. We have had the appropriate experience for almost ten years. The implemented plants have capacities ranging from 5,000 to 90,000 m³ /h. Because of the large number of different paint systems, individual experiments are usually necessary in our pilot plant in order to find the correct solution for the individual case.

Spray walls and spray booths with dry separation via cartons. For lower utilisation times or overspray quantities RES dry spray booth For lower utilisation times or smaller overspray quantities, spray systems with dry separation offer a meaningful alternative to water-sprinkled systems. The Rippert modular spraying system type RES enables individual adaptation to the respective case of need. The filter system of the RES dry spray wall consists of individual square cardboard boxes. A sheet metal frame serves as a support structure for the filter box. In order to save costs, there is a possibility to vary the individual filter boxes in the spray booth, without exchanging all of the filter elements. Function The overspray is caught by the exhaust air stream and fed to the filter. The solids are filtered out here, while the cleaned exhaust air is blown out into the open air by the fan. Versions The basic version consists of a wall with a two-fold filter stage. Paper filter boxes form the first filter stage. A glass fibre fine filter arranged directly behind it represents the second filter stage. The attached radial fan is equipped with spark protection in the suction nozzle as well as an explosion-proof motor. The spray booth can additionally be equipped with removable or fixed side and ceiling panels. The RES dry spray booth is available in galvanised sheet metal or in stainless steel. Advantages Cleaning / maintenance The spray wall is designed such that the filter elements can be exchanged with little effort in a very short time. Once it is saturated, the filter box is removed from the sheet metal frame and disposed of in an environmentally-friendly manner.
