What are some non-medical uses of Woods lamps?

Woods lamps have a variety of non-medical uses across different fields. Here are some of the key applications:

### Forensic Science
- **Crime Scene Investigation**: Woods lamps can be used to detect biological fluids such as semen and urine at crime scenes. These substances fluoresce under UV light, aiding forensic investigators in identifying and collecting evidence.
- **Document Examination**: They help in detecting alterations or forgeries in documents. Certain inks and materials used in forgery may fluoresce differently under UV light, allowing experts to identify suspicious documents.

### Veterinary Medicine
- **Diagnosing Infections**: Veterinarians use Woods lamps to check pets for bacterial, fungal, or parasitic infections. Conditions such as ringworm in animals can be identified through fluorescence.
- **Skin Condition Assessment**: Similar to human dermatology, Woods lamps can assess pigmentation disorders and other skin conditions in animals.

### Industrial and Manufacturing
- **Metal Fatigue Detection**: In industrial settings, Woods lamps are used alongside fluorescent penetrant inspection to detect surface cracks and metal fatigue in machinery and structures. This helps in ensuring the safety and integrity of equipment.
- **Quality Control**: They can detect contaminants or imperfections in products during manufacturing processes. For example, in the production of certain materials, Woods lamps can reveal the presence of foreign particles or defects that are not visible under normal light.

### Entertainment and Hospitality
- **Nightclub Security**: Woods lamps are used in nightclubs to check the validity of re-entry stamps. The fluorescent stamps are easily visible under UV light, allowing security personnel to verify customer access.
- **Theatrical Effects**: In theaters and entertainment venues, Woods lamps can create special lighting effects for performances and events, adding a unique visual element to productions.

### Security and Authentication
- **Passport and Currency Verification**: Immigration officers and banks use Woods lamps to check the authenticity of passports and currency. Certain security features in passports and banknotes fluoresce under UV light, helping to identify counterfeit documents and money.
- **Art and Document Authentication**: They can also be used to authenticate artworks and historical documents by revealing specific fluorescence patterns or materials used in their creation.

### Education and Research
- **Laboratory Use**: In molecular biology laboratories, Woods lamps are used to detect compounds with fluorescent tags, aiding in research and experiments.
- **Teaching and Demonstrations**: They serve as educational tools in classrooms and demonstrations to illustrate principles of fluorescence and UV light, enhancing the learning experience for students.

### Mineralogy and Gemology
- **Mineral Detection**: Woods lamps are used in mineralogy to identify and classify minerals based on their fluorescence. Different minerals exhibit distinct fluorescence patterns under UV light, helping researchers and collectors in their work.
- **Gemstone Evaluation**: In gemology, they can assess the quality and authenticity of gemstones by revealing fluorescence characteristics that are unique to specific types of gems.

Display and Art
- **Art Installations**: Woods lamps are used to display fluorescent paint in art installations and sculptures, creating visually striking effects that enhance the artistic expression.
- **Museums and Exhibitions**: They can highlight specific features or details in historical artifacts and artworks during exhibitions, providing viewers with a unique perspective on the displayed items.
