A broad variety of gas transmission cells are : Gas Cells analysis of gas & vapour phase components in IR optical spectroscopy. These range from short path length gas cells for percent level concentration measurement, to long path length gas cells for part-per-billion concentrations. Options include fixed and variable path length gas cells, as well as ambient temperature and heated gas cells. The windows that can be used with the gas cell include NaCl, KBr, CaF2, BaF2, or ZnSe infrared transmission windows, which are mounted in an optical spectrometer. Knight Optical supply high quality Gas Cells optical components made to our exacting specification. For more information read the 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

Knight Optical can offer Pellin-Broca Prisms for use within Atomic Spectroscopy. We supply a range of Pellin-Broca Prisms 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 within Atomic Spectroscopy. Pellin-Broca Prisms are designed with a given material, angle and wavelength in mind to perfectly deviate a beam of the given wavelength by 90 degrees. These are often used to separate beams of differing colours and as such are ideal for use in optical atomic spectroscopy or to separate outputs of a multi-line laser. For more information read PDF…

Highperformance versatile AFM Optical access from top, side and bottom optimized for Raman, TERS and SNOM Flexible optical design providing any combination of excitation/collection configurations Automated AFM laser, probe and photodiode alignment Userfriendly change of wavelength of AFM registration system laser and photodiode Easy and userfriendly change of objectives Integration with IR sSNOM (optional) Since 1998 NTMDT has been successfully integrating AFM with optical microscopy and spectroscopy techniques. More than 30 basic and advanced AFM modes including HybriD ModeTM are supported providing extensive information about the sample surface physical properties. Integration of AFM with confocal Raman/fluorescence microscopy provide the widest range of additional information about the sample. Simultaneously measured AFM and Raman maps of exactly the same sample area provide complementary information about sample physical properties (AFM) and chemical composition (Raman).
