The Ultimate Guide to Understanding UV365nm vs UV405nm

Introduction

Regarding the ultraviolet light,different wavelength have different applications.Two common wavelengths are UV365nm and UV405nm Which our DE-215 and DE-315 refers.In this blog,we are gonna to revel the difference between UV 365nm and UV405nm,helping to clarify the difference and choose the suited for your needs.

What is UV Light?

The UV light is a type of non-ionizing radiation that is emitted by the sun and artificial sources.The beneficial effects of UV radiation include the production of a vital nutrient, vitamin D. However,overexposure may causes skin cancers.Keeping you and others protected from UV is very important.

The UV light is divided into three main categories:

  • UV-A (315-400nm):Known as long-wave UV, it is less harmful and often used in black lights and curing processes.
  • UV-B (280-315nm):Medium-wave UV, responsible for causing sunburn and used in phototherapy.
  • UV-C (100-280nm):Short-wave UV, used for sterilization and disinfection.

What is UV 365nm?

UV 365nm falls into the UV-A category. It’s close to the visible light spectrum but still beyond what the human eye can see. This wave band is most common during the practical use. Here’s what you need to know about UV 365nm:

What is UV 405nm?

 

UV 405nm is also in the UV-A Spectrum and closer to visible violet light,but it can sometimes appear as a faint violet light,which is useful in applicantions where some visibility is beneficial.  

Key Differences Between UV 365nm and UV 405nm

Feature

UV 365nm

UV 405nm

Wavelength

365 nanometers

405 nanometers

Visibility

Invisible to human eye

Faint violet visible light

Common Applications

Resin curing, forensic analysis, security

3D printing, coating curing, adhesives

Curing Depth

Deeper penetration

Faster curing, less penetration

Cost

Generally more expensive

More cost-effective

Choosing the Right Wavelength for Your Application

Choosing between UV 365nm and UV 405nm depends on your specific needs:

  • Use UV 365nm if:You need deeper penetration, such as for thick resin curing or high-precision applications.
  • Use UV 405nm if:Speed and cost are more critical, such as in rapid 3D printing or when working with materials that cure quickly.

The fluorescence effect is much stronger at 365nm than at 405nm.

Conclusion

Better understanding the differences between UV365nm and UV405nm can help you to determine your right tools for your application.
