The QBC® ParaLens™ Advance Fluorescent Microscope Attachment is a cutting-edge attachment designed to provide the many benefits of LED Fluorescence Microscopy to any light microscope. LED Fluorescence Microscopy offers improved detection of many infectious diseases and has been recommended by the World Health Organization for use in Tuberculosis screening.
The QBC ParaLens Advance is simple to use and requires no daily cleaning. It is also sturdy with no liquid handling or moving parts.
The cutaway diagram above demonstrates the technology behind the QBC ParaLens Advance Fluorescent Microscope Attachment. Standard RMS Threading (1) is used to easily attach the QBC ParaLens Advance main body to any compound light microscope as an objective (Note: Adapter rings are available for non-standard sizes). All filters are contained in a detachable filter set arm (2) that can be removed to easily switch between objectives.
The QBC ParaLens Advance utilises epifluorescence microscopy, meaning that the light is transmitted from above the sample, rather than passing through from below. The ParaLens Advance's light comes from its LED light source, which attaches to the distal end of the filter set arm (3), producing blue light with a 410-511 nm wavelength.
After passing through the focusing lens (4), light in the filter set arm then passes through an excitation filter (5) that only allows light in the 385-480 nm range to pass into the main chamber. A dichroic beam splitter (6) directs blue light toward the sample, where it will excite any substances that have absorbed fluorescent stain.
The emitted light from the sample is focused by powerful objective lenses (7) as it travels back toward the viewer. It now has a longer wavelength than blue light which allows it to pass through the dichroic mirror. An emission filter (8) is present to reduce background noise and optimise the signal for viewing.
