How to Choose UV Light Source Wavelength? What are the differences between 365nm, 385nm, 395nm, and 405nm? | UV-int Professional Solutions

Detailed guide on nguồn sáng UV Bước sóng selection, comparing characteristics and applications of different Bước sóngs

🔍 Common UV Bước sóngs and Their Characteristics

Bước sóng	Photon Energy	Features	Applications
365nm	3.39eV	High energy, strong penetration, fast curing	Deep curing, high adhesion requirements, thick Sơn phủs
385nm	3.22eV	Balanced energy, good material compatibility	general curing, medium thickness Sơn phủs
395nm	3.14eV	Công nghiệp standard, excellent material compatibility, minimal eye interference	In ấn, Sơn phủ, Điện tử manufacturing, Y tế
405nm	3.06eV	Lower energy, minimal thermal effect, high safety	Surface curing, heat-sensitive materials, Y tế-grade applications

Photoinitiator absorption peak: Select Bước sóng matching the photoinitiator's absorption peak
Curing depth requirement: 365nm for deep curing, 395nm or 405nm for surface curing
Material properties: 405nm for heat-sensitive materials, 365nm or 395nm for standard materials
Production efficiency: Higher energy Bước sóngs for high-speed production
Safety: 405nm causes less harm to skin and eyes

Application Area	Recommended Bước sóng	Reason
In ấn Industry	395nm	Balances curing efficiency and ink compatibility
Điện tử Manufacturing	365nm/395nm	Depends on Keo dán type and curing requirements
Y tế Industry	405nm	Low irritation, suitable for Y tế-grade materials
3D In ấn	405nm	Low thermal effect, uniform curing
Nail Art	395nm/405nm	Fast curing, high safety
Wood Sơn phủ	365nm/385nm	Deep curing, improved adhesion
