1. Working Principle of UV Light Inspection

UV light, also known as ultraviolet light, emits wavelengths ranging from 320 to 400 nm and can stimulate certain substances to fluoresce. In endoscope lens inspection, UV light can reveal issues that are difficult to detect with the naked eye, such as:

• Microscopic contaminants (e.g., grease, dust)
• Damage to lens coatings
• Residues of organic materials or pollutants

This inspection method leverages the interaction between UV light and specific substances to quickly detect abnormalities on the lens surface.

2. Main Uses of UV Light in Borescope Lens Inspection

(1) Cleanliness Inspection

UV light can detect microscopic particles and contaminants that are invisible to the naked eye. Through UV reflection and fluorescence, it quickly determines whether the lens is clean.

(2) Lens Coating Integrity Inspection

Many endoscope lenses feature anti-reflective or anti-fouling coatings, which exhibit a uniform optical effect under UV light. If the coating is scratched, damaged, or aged, abnormal light spots may appear.

(3) Detection of Organic Contaminants

UV light can cause certain organic substances (e.g., proteins, lipids) to fluoresce, allowing detection of contamination residues on the lens, particularly in industries such as healthcare and food processing.

(4) Material Aging Detection

Over time, materials in endoscope lenses may degrade or lose performance. Under UV light, aged areas may exhibit different optical reactions from normal areas, helping to predict the lens’s lifespan.

 

3. Advantages of UV Light Inspection

Advantages	Description
High Efficiency	Short inspection time, instant issue detection
Non-Destructive	Does not cause secondary damage to the lens
High Precision	Can detect microscopic scratches or contaminants
Wide Applicability	Suitable for various industries, especially high-precision inspection fields
Cost-Effective	One-time equipment investment for long-term use

4. Application Scenarios in Different Fields

Industrial Manufacturing

• Inspect industrial endoscopes for contamination or damage in harsh environments.
• Ensure lens cleanliness to improve imaging precision.

Medical Field

• Ensure endoscope lenses are residue-free after sterilization to avoid cross-contamination.
• Inspect lens coatings for damage to maintain diagnostic quality.

Aerospace

• Inspect lens aging under high temperatures, vibrations, and other conditions.
• Ensure inspection equipment is functioning optimally.

5. How to Properly Use UV Light for Inspection

When using UV light to inspect endoscope lenses, follow these steps:

1. Prepare the Environment
   • Ensure the inspection environment is dimly lit for better observation of fluorescence.
   • Use a clean workspace to avoid secondary contamination.
2. Clean the Lens Surface
   • Pre-clean the lens to remove visible dirt.
   • Use appropriate solvents to remove grease.
3. UV Light Illumination
   • Shine UV light evenly on the lens surface and observe for fluorescent spots or abnormal light reflections.
   • Inspect coating uniformity and record suspicious areas.
4. Analyze Results
   • Based on inspection results, determine whether further cleaning or lens repair is needed.
   • Document inspection data for future reference.
