- Superiority
In the UV-C band region (250 to 280 nm), about twice as high reflectance as aluminum substrate (UV479: 95.6% / Aluminum substrate : 49.3%); High durability allows operation even at high output; Our products enable customers to apply for complexity in shape.
- Typical Use
Highly reflective COB / SMD substrate; Higher output of UV sterilization / disinfection equipment
