UV to Visible Light Converter Fluorescent Glasses
Lumilass
- Lumilass can convert a faint UV source of 200 – 400 nm light into visible spectrum in high efficiency.
- Minimum sensitivity of – 1 µW/ cm2 for all emissions.
- Since a large amount of luminous ions are contained, Lumilass has high sensitivity that allows for visible light detection.
- Transparent, high in homogeneity.
- Lumilass has excellent machinability, so it can be processed in various forms.
- Superior durability and water resistance
- Lumilass keeps high performance after long-hours irradiation with ultraviolet (UV) light.
- Available in red (R7), green (G9) and blue (B) emissions.
- RoHS: Compliant
- Application: fluorescence microscopy, excimer laser detection, a standard test material for fluorescence characteristics.
