25 Feb 2021 LASER COMPONENTS offers a comprehensive range of fluorescence filter sets from our partner Omega Optical. Standard sets are available for over 180 dyes and fluorophores. Long pass emission sets and narrowband sets are available for samples with multiple tags.
Fluorescence sets typically consist of an excitation filter selecting the range of excitation wavelengths, a dichroic mirror and an emission filter blocking the excitation light. The excitation filter is a band-pass which transmits the desired wavelengths and reflects or absorbs the unwanted wavelengths. The transmitted light is reflected through 45° by the dichroic mirror, directing the excitation wavelengths to the sample and allowing the emission to transmit back though. Finally, the emission filter blocks the excitation light and transmits the desired fluorescence to the detector. These filters produced by Omega Optical are characterised by good blocking out of band and high transmission of desired wavelengths to produce a good quality image with a high signal-to-noise ratio.
Filter sets, components, and holders are available for all major microscope manufacturers and models, including Leica, Nikon, Olympus, and Zeiss.
