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

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

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.

Looking to improve you medical system? Then look no further. Knight Optical presents to you their Dichroic colour filters range.

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.

The Image Processing System (IPS) software enable to process digital radiography to find and display the defects of a component. With the different filters and zoom capabilities, the most difficult and tiniest defect can be quickly located. IPS can be linked with the acquisition module to receive the images acquired. This can be done on the same computer or using a separate reviewing station. Integration is also accomplished with the automation module, showing the images in real time as well as querying the (optional) database. IPS has an extensible architecture, this means you can expand the features using add-on modules. Balteau provides a number of modules and custom ones can be developed on demand. Existing add-on: SRb (Basics Spacial Resolution), SNR (Signal to Noise Ratio), DICONDE (Reader & writer), DB (Database), & more on demand.
