Quartz Sheets for UVC Germicidal Lamp-Eva

Quartz Sheets for UVC Germicidal Lamp

A UVC disinfection lamp manufacturer from Spain approached us for quartz cover sheets for their new air sterilizer series. They previously chose cheaper borosilicate sheets, yet low UVC transmittance reduced sterilization efficiency and failed EU photobiological safety testing.

In technical communication, the client confirmed core indicators: 254 nm UVC transmittance ≥92%, thermal shock resistance for continuous lamp operation, scratch-free surfaces and tight thickness tolerance. They also asked for test reports to support CE filing. Our team sent standard quartz samples together with transmittance test reports and suggested fire-polished edges to avoid cracking during assembly.

The client’s R&D team ran lamp aging and disinfection efficiency testing for over 2500 hours. Their report confirmed quartz sheets maintained stable UV output, while borosilicate blocked most UVC energy. After verifying sample performance, they confirmed the drawing, quantity and delivery lead time and issued the mass-production order.

After assembly, the upgraded UVC lamps passed EU safety certification smoothly, with sterilization efficiency increased by nearly 22%. The client received positive market feedback and expanded their product line. They now order quartz sheets monthly and value our clear parameter confirmation and reliable optical consistency.

This case illustrates why quartz sheets are irreplaceable for certified UVC disinfection products.
