Fluorescent mineral sample imaged with the Keyence + NIGHTSEA systems

Fluorescence Adapter for Keyence VHX-5000

The NIGHTSEA Model SFA Fluorescence Adapter system adds fluorescence to the Keyence VHX-5000 Series Digital Microscope using the same approach that we take with conventional stereo microscopes – the combination of an LED-based light source with a matching barrier filter. The system consists of a free-standing lamp that accepts modular LED light heads, a barrier filter mounted in a holder that slips over the end of the Keyence lens*, and a pair of barrier filter glasses.

*Fits on the VH-Z00, VH-Z20, VH-Z50x and VH-Z100 series lenses

Industrial application: Examining electronic components that were embedded in epoxy, cross-sectioned, polished, and highlighted with a fluorescent epoxy-like dye. Imaged using the Keyence VHX-5000 with the NIGHTSEA fluorescence adapter. Royal Blue excitation-emission set with longpass filter, and white light added to better show the components.


Wavelengths

There are five excitation/emission combinations available for the system.

  • Ultraviolet (UV) – Ex – 360 – 380nm, Em – 415nm longpass
  • Violet (VI) – Ex – 400 – 415nm, Em – 460nm longpass
  • Royal Blue (RB) – Ex – 440 – 460nm, Em – 500 nm longpass or 500 – 560nm bandpass
  • Cyan (CY) – Ex – 490 – 515nm, Em – 550nm longpass
  • Green (GR) – Ex – 510 – 540nm, Em – 600nm longpass
