Dual-Wavelength UV Technology

UVisionDx's breakthrough dual-wavelength UV illumination system combines 365nm UV-A and 405nm violet light to reveal both organic residues and bacterial contamination in a single inspection.

Two Wavelengths, Complete Detection

365nm UV-A

Organic Residue & FPI Detection

The 365nm wavelength is the industry standard for fluorescent penetrant inspection (FPI) and organic residue detection. It excites fluorescent dyes and causes proteins, fats, and carbohydrates to fluoresce, revealing:

  • Surface cracks in aerospace and industrial components
  • Protein, fat, and carbohydrate residues
  • Incomplete cleaning in food processing equipment
  • Fluorescent penetrant dye indications

405nm Violet

Bacterial Pathogen Detection

The 405nm wavelength is a breakthrough innovation for biofilm and bacterial detection. It excites porphyrins and other compounds naturally present in bacterial cells, causing them to fluoresce without any added dyes or reagents:

  • 15+ validated bacterial pathogens including Listeria, Salmonella, E. coli
  • Biofilm in food processing and pharmaceutical equipment
  • Bacterial contamination in water systems
  • Real-time detection without lab analysis

Scientifically Validated Pathogen Detection

405nm Wavelength: Proven Bacterial Detection

The 405nm wavelength has been extensively studied and validated for bacterial detection through natural fluorescence. Research has demonstrated that bacterial cells produce porphyrins and other fluorescent compounds that emit visible light when excited by 405nm violet light.

Validated Bacterial Pathogens (15+)

  • Listeria monocytogenes
  • Salmonella species
  • Escherichia coli (E. coli)
  • Pseudomonas aeruginosa
  • Staphylococcus aureus
  • Bacillus species
  • Enterococcus species
  • Campylobacter species
  • Klebsiella pneumoniae
  • Proteus mirabilis
  • Acinetobacter baumannii
  • Clostridium species
  • Streptococcus species
  • Vibrio species
  • Yersinia enterocolitica

No Reagents Required

Unlike traditional methods, 405nm detection requires no dyes, stains, or chemical reagents. Simply illuminate and observe natural bacterial fluorescence.

Real-Time Results

Instant visual detection eliminates the 24-72 hour wait for laboratory culture results. Make informed decisions immediately.

Non-Destructive

Inspect equipment in-place without disassembly. Safe for use on food-contact surfaces and sensitive equipment.

Technology Applications

Industrial NDT

The 365nm wavelength is essential for fluorescent penetrant inspection (FPI), the most sensitive method for detecting surface-breaking defects in non-porous materials.

  • Aerospace turbine blade inspection
  • Weld quality verification
  • Casting defect detection
  • Fatigue crack monitoring

Hygiene & Biofilm Detection

The 405nm wavelength revolutionizes hygiene verification by revealing bacterial contamination that traditional methods miss.

  • Food processing CIP system validation
  • Pharmaceutical cleanroom monitoring
  • Water system biofilm detection
  • Brewery and dairy equipment inspection
