Hirox Fluorescence Images

 

The NIGHTSEA Model SFA adapter system adds a versatile fluorescence capability to the Hirox digital microscope series. It can be used in a wide variety of applications, as illustrated by the examples below. Scroll down, or jump to any section of interest.

Electronic component failure analysis

Examining electronic components that was embedded in epoxy, cross-sectioned, polished, and highlighted with a fluorescent epoxy-like dye. While the manufacturer of the fluorescent dye recommended excitation with ultraviolet light, our Royal Blue light head was used for these images, and was found to be superior to ultraviolet. You can read more about this kind of inspection application in the article on this web site.

Concrete thin section

The images below were made from a 20μm concrete thin section with the NIGHTSEA Royal Blue excitation. As with the electronic components above, the manufacturer of the fluorescent dye recommended excitation with ultraviolet light. Our Royal Blue light head was used for these images and was found to be superior to ultraviolet. You can read more about this kind of inspection application in the article on this web site.

Gel defect in a nylon granule

Nylon 6,6 granules can manifest a process defect called ‘gel’ and if there is too much of this in a production batch it can compromise downstream production. The gel shows up as a brighter fluorescent area within the fluorescing granule. You can read more about this in our application article. Images made with Royal Blue excitation.

 


Naturally fluorescent mineral

This mineral sample, collected at the Sterling Hill Mine in Ogdensburg, New Jersey, contains willemite (green fluorescence), calcite (red fluorescence) and franklinite (black – no fluorescence).


Bone fragment
