UV-LED CHAMBER BSL-02: Flexible UV irradiation

The UV LED chamber BSL-04 is the largest irradiation chamber in the BSL series. The high irradiance combined with the exact dose control offers a unique reproducibility for perfect results! The wavelengths 365 nm, 385 nm, 395 nm, 405 nm and 450 nm are available for your application. Due to the irradiance of up to 110 mW/cm² and the high homogeneity, even very large parts or batches can be irradiated. For high irradiances, the UV LED chamber can be ordered completely with one LED wavelength. A particularly flexible application is possible when two separately controllable LED wavelengths are ordered. Compared with our irradiation chambers of the BS series, the BSL-04 offers an irradiance that is 14 times as high. The high irradiance allows for extremely short exposure times. With the high homogeneity of the irradiation, the samples can also be positioned as needed.

The BS-03 is a medium-sized, rugged irradiation chamber for time- or dose-controlled irradiation of samples with UVA, UVB, or UVC. The chamber can be fully equipped for one of the spectral ranges UVC, UVB, or UVA to achieve the highest irradiance. Alternately, the use of two separately controlled lamp groups for different spectral ranges allows for especially flexible operation of the chamber. The interior irradiation chamber has a base area of 68 x 49 cm² and a height of 32 cm. The sliding sample carrier facilitates loading and unloading. With a load of up to 20 kg, this can withstand all demands. The sample chamber operating temperature is about 25°C so that thermal damage to the specimen is avoided. Due to the high uniformity of the irradiation, the samples may be positioned in any order. Two irradiation controls are available for the BS-03: the UV-MAT and the UV-MAT Touch.

The irradiation chamber BS-02CT is a chamber to test samples according IEC 60335-1: “Household and similar electrical appliances – Safety – Part 1: General requirements - Edition 5.2” This test is designed for non-metallic materials that are exposed to direct or reflected UVC radiation from 200 nm to 280 nm. The test can be used to test radiation stability against UVC radiation that can cause aging like discolorations, changes in material properties, crack formation and smell. Therefore the UVC low pressure mercury lamps emit a continuous spectral irradiance of 10 W/m² at 254 nm. IR heater heat up the samples so that a black-panel temperature of 63 °C ± 3 °C can be reached and controlled. The time can be set to an exposure duration of 1000 h. The irradiation chamber BS-02CT can also be used to test material properties that are disinfected by UV-C. Typically the UVC dose of a daily disinfection for a period of two years can be accelerated to 12 hours.

The irradiation chamber BS-02 is compact, robust equipment for the time- or dose-controlled irradiation of samples with UV radiation. The chamber can be fully equipped for one of the spectral regions UV-C, UV-B, or UV-A to achieve the highest irradiance. Alternately, the use of two separately controlled lamp groups for different spectral regions allows for especially flexible operation of the chamber. With interchangeable lamps, the BS-02 is really flexible. No tools are required for lamp replacement. The interior irradiation chamber has a base area of 49 x 32 cm² and a height of 23 cm. The sample chamber operating temperature is about 25°C - 30°C so that thermal damage to the specimen is avoided. Due to the high uniformity of the irradiation, the samples may be positioned in any order. For the BS-02 we offer two irradiation controllers, the UV-MAT and the UV-MAT Touch.
