Jelight UVGL-55

is a 6 W dual-wavelength handheld UV lamp providing both 254 nm shortwave and 365 nm longwave ultraviolet illumination from a split UV tube. A wavelength selector allows users to switch between UV wavelengths for fluorescence examination, laboratory inspection, mineral analysis, photochemical research, and other applications requiring both UV-A and UVC illumination.

Applications

Laboratory UV Inspection

The UVGL-55 provides selectable 254 nm and 365 nm ultraviolet illumination for laboratory inspection, fluorescence observation, sample examination, and analytical procedures requiring access to both shortwave and longwave UV.

Fluorescence Examination

Different compounds and materials can respond differently to shortwave and longwave ultraviolet radiation, making the UVGL-55 useful for comparative fluorescence examination and identification of UV-responsive materials.

Mineral and Lapidary Examination

The combination of 254 nm and 365 nm output allows minerals and geological specimens to be examined under both shortwave and longwave UV, supporting mineral identification, lapidary work, and specimen analysis.

Photochemical and Analytical Research

Selectable UV wavelengths support photochemical experiments, phosphorescence studies, analytical procedures, and other research applications requiring controlled shortwave or longwave ultraviolet illumination.

Industrial and Field Inspection

The handheld configuration provides a portable dual-wavelength UV source for quality control, inspection, troubleshooting, and field applications where both 254 nm and 365 nm illumination may be required.

FAQs

How do you switch between 254 nm and 365 nm?

The UVGL-55 uses a wavelength selector with the split UV tube, allowing the user to expose the section corresponding to the desired shortwave or longwave UV output.

What safety precautions are required when using the UVGL-55?

Both 254 nm and 365 nm ultraviolet radiation can present eye and skin exposure hazards, with 254 nm UVC requiring particular care. Avoid direct exposure and use appropriate UV shielding, protective eyewear, face protection, clothing, and operating procedures for the selected wavelength and application.
