Fluorescence Applications

Fluorescence microscopy has become a vital asset in biomedical science thanks to the many advantages it offers over traditional optical microscopy. With the ability to reveal the presence of a single molecule, and to study intracellular distribution, fluorescence microscopy really has become an incredibly powerful tool.

Should your fluorescence microscopy application use multiple fluorophores, or laser technology, or is of a more complex set-up than regular microscope applications, Knight Optical’s technical experts will work with you to meet your specifications.

Emission and Excitation Filters

Custom engineered pairs of bandpass filters can be crafted to match your precise excitation wavelength and the resulting emission wavelength of the individual fluorophore in use. The images delivered by our filter sets are of exceptional quality and brightness when used in a fluorescence microscope thanks to the high transmission values and the deep blocking of unwanted light. For images with an outstanding signal-to-noise, these are the filters to choose

Dichroic Beamsplitters

Dichroic beamsplitters are specialist interference filters designed to reflect or pass light of specific wavelengths when placed in the light path. Their broad transmission and reflection ranges are separated by a steep slope, making them the perfect choice for fluorescence imaging applications. Knight Optical is able to engineer these filters with splitting wavelengths to match specific excitation and emission filters.

Fluorescein Leak Detection Filters

A crucial diagnostic tool in fields such as ophthalmology, optometry and angiography, fluorescein leaks are used to detect everything from incompetent blood vessels to diseased retinal pigment. Leak detection filters play a vital role in fluorescein leakage mapping instrumentation. These bandpass filters are fully customisable in terms of minimal attenuation for fluorescent light and high attenuation for reflected light so that accuracy and performance are fully enhanced.

Blood Analysis Applications

Thanks to significant innovation in biomedical optics, the field of blood analysis has over the past few years been revolutionised. With high end optical filter coatings and multi-element objective lenses playing a vital role in the advancement of haematology, the collection of information vital to the diagnosis and treatment of major blood related ailments has become considerably more efficient with devices now easier to use, less invasive, far more portable and faster to deliver results. Knight Optical can supply;

  • Cube Beamsplitters (CBS)
  • Plate Beamsplitters
  • Precision Lenses
  • Aspheric Lenses
  • Prisms

Understanding Quality

Our rigorous testing procedures – using advanced metrology equipment and skilled QA inspectors – ensure all our products satisfy even the most specific requirements. This applies to one-off custom parts and large production runs. Every single component we supply is proven to perform. We will also provide you with all the information you require for your documentation. We can reassure you that there is transparency on your ordered items including a metrology report and a certificate of conformance to quality standards. We are able to provide you with as much information as required to ensure that legal obligations are met, allowing your instrument to be approved for use as soon as possible.
