Dichroic Filters for Medical Analysers

Knight Optical can offer dichroic bandblocking filters for use in Fluorescence Microscopy. We supply a range of dichroic bandblocking 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 fluorescence microscopy. Dichroic bandblocking filters are used to block a specific wavelength band and transmit the rest. Our Dichroic bandblocking filters are usually made for bands between 300-1200nm. Our dichroic filters are usually specced for a 0° AOI. Use at a 45° results in a CWL shift of around 35-50nm. They are used as beamsplitters in fluorescence microscopy to transmitting For more information read PDF….

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

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.

Knight Optical can offer Toroidal Mirrors for use within Optical Systems. We supply a range of Toroidal Mirrors 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 with Optical Systems. Our Toroidal Mirrors are designed to minimise astigmatism when used in off-axis geometry. They are easier to manufacture than parabolic or ellipsoidal mirrors and therefore can be made much cheap with the same quality. Toroidal mirrors are used for correction of aberration in a range of scientific instrument applications such as spectroscopes monochromators and imaging devices. For more details read PDF…
