With the UV LED chamber BSL-02, we offer you a versatile irradiance chamber on a basis of high quality UV LEDs. The most common UV curing adhesives can be applied, due to the high irradiance of 400 mW/cm².

Compared to our irradiance chambers of the series BS, the series BSL-02 offers the 40-fold irradiance. In addition, the high irradiance allows for very short exposure times. 

With the typical UV LED characteristics like „Instant-Start“, the dimmability and the long service life, the BSL-02 is ideal for laboratory tests and the manual production. The irradiance is adjustable from 2% to 100%. The integrated timer controls the irradiance precisely. For even better results, we recommend one of our calibrated UVA+ sensors. The dose control is already integrated in the UV-MAT Touch and UV-MAT control units in the BSL-02 UV LED chamber. By means of an optional sensor, the UV-MAT measures the irradiance continuously, and stops the irradiance at the set target dose.


For different applications, wavelengths of 365 nm, 385 nm, 395 nm, 405 nm and 450 nm are available. 
Optionally, two wavelengths can be controlled separately.  That way, the irradiance chamber can be optimal customized for the requirements of the photoinitiator. We offer the BSL-02 in two versions:

  •     0 to 400 mW/cm² (Version HO)
  •     0 to 200 mW/cm² (Version ECO)

Due to the low heat input of the UV-LEDs and the temperature of approximately 40° in the sample chamber, thermal damages of the samples are minimized. Because of the high homogeneity of the irradiance, the samples can be placed in any position.

The BSL-02 has compact outer dimensions, but provides sufficient room in the sample chamber. The floor space is 46 x 32 cm and the height is 25 cm. In the completely closed and monitored irradiation chamber, the operating personnel are fully protected from the UV radiation.
