UV handheld lamps for fluorescence excitation and inspection
Herolab UV analysis lamps excite fluorescent substances, for example in laboratory analyses, mineral examination, or inspection of fluorescent markings and coatings. Suitability depends on the test method, wavelength, and material.
Wavelengths and versions
- S — short-wave UV: 254 nm.
- M — medium-wave UV: 312 nm. When selecting a replacement tube, the catalog designation “312 (302) nm” must be clarified against the actual installed configuration.
- L — long-wave UV: 365 nm.
- BLB versions: 365 nm without an additional blocking filter.
Depending on the model, single or combined wavelengths and different tube powers and filter areas are available. The plastic-coated lightweight metal housing and optional tabletop stand (29 50 100, height 50–270 mm) are described in the product overview.
Model series and tube configurations
- Single wavelength: UV-4 with 1 × 4 W (S, L, or BLB); UV-6 and UV-12 with 1 × 6 W and 2 × 6 W, respectively; UV-8 and UV-16 with 1 × 8 W and 2 × 8 W; UV-15 and UV-30 with 1 × 15 W and 2 × 15 W. Series from UV-6 onward are listed in the catalog in S, M, L, and BLB versions.
- Dual wavelength S/L: UV-4, UV-6, UV-8, and UV-15, with one tube per wavelength.
- Dual wavelength S/M or M/L: UV-6, UV-8, and UV-15, with one tube per wavelength.
The watt ratings refer to each tube, not the emitted UV radiant power. The irradiance values in the catalog were measured at a distance of 15 cm and cannot be applied directly to other distances or operating conditions. Mains supply: 220–240 V, 50/60 Hz; according to the catalog, a 110–120 V version is available on request.
Selecting the right model
Please specify the test material, required wavelength, area to be illuminated, and working distance. Tube power in watts must not be equated with UV irradiance at the test object.
Fluorescent markings can assist visual inspection; they do not demonstrate successful disinfection. Use for UV curing must be compatible with the material and validated process.
Safe handling
UV radiation can injure eyes and skin. Follow the operating instructions and use shielding and protective measures appropriate to the wavelength.
