Jelight UVGL-25

is a compact dual-wavelength UV lamp providing selectable 254 nm shortwave and 365 nm longwave ultraviolet illumination from two separate 4 W UV tubes. Its portable design makes it well suited for fluorescence inspection, laboratory analysis, mineral examination, security inspection, and applications requiring convenient access to both UV-A and UVC wavelengths.

Applications

Laboratory UV Inspection

The UVGL-25 provides both 254 nm and 365 nm illumination for laboratory inspection, fluorescence observation, analytical procedures, and applications that benefit from switching between shortwave and longwave UV.

Mineral and Lapidary Examination

Different minerals and geological specimens can fluoresce differently under shortwave and longwave UV, making the UVGL-25 useful for mineral identification, lapidary work, and specimen examination.

Fluorescence and Analytical Work

Selectable 254 nm and 365 nm output supports fluorescence excitation and analytical procedures where either shortwave UVC or longwave UV-A illumination may be required.

Security and Fraud Detection

The lamp can be used to inspect fluorescent markings, security features, documents, and materials that respond to ultraviolet radiation.

Research and General UV Examination

The compact dual-tube design supports laboratory, educational, field, and research applications requiring convenient access to both shortwave and longwave UV illumination.

FAQs

Does the UVGL-25 use one split tube or two separate tubes?

The UVGL-25 uses two separate 4 W UV tubes: one 254 nm shortwave tube and one 365 nm longwave tube.

What safety precautions are required when using the UVGL-25?

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