UV-LED chamber BSL-03 – 64 × 49 cm sample tray, up to 220 mW/cm²
The UV LED chamber BSL-03 is the second largest LED irradiation chamber in the BSL series and cures large-area components as well as medium-sized laboratory batches. Within an interior of 68 × 51 × 31 cm it reaches up to 220 mW/cm², 22 times the irradiance of the BS series, at 365, 385, 395, 405 or 450 nm. Together with the UV-MAT dose control this gives short exposure times at a reproducible dose; UV LEDs start instantly, are dimmable and have a long service life.
The most common UV curing adhesives and lacquers can therefore be applied. 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.
With the high homogeneity of the irradiation, the samples can also be positioned as needed.
The dose control is already integrated in the UV-MAT Touch and UV-MAT control units in the BSL-03 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.
The integrated timer already controls the irradiation precisely. For even better results, we recommend one of our calibrated UVA+ sensors. Dose control is already integrated in the UV LED chamber BSL-03 in the UV-MAT Touch and UV-MAT control units. With an optional sensor, the UV-MAT continuously measures the irradiance and stops irradiation when the set target dose is reached.
The BSL-03 is available in two versions:
- 0 to 220 mW/cm² (Version HO)
- 0 to 110 mW/cm² (Version ECO)
The sample chamber is actively air-cooled; together with the low heat input of the UV LEDs the thermal load stays manageable even in the HO version at 220 mW/cm². The high uniformity across the 64 × 49 cm sample tray allows parts to be positioned freely.
The sample room has a floor space of 64 × 49 cm and a height of 25 cm. Parts that must be bonded or cured can be positioned easily on the movable sample carrier.
Thanks to the fully enclosed and monitored irradiation chamber, operating personnel are completely protected from UV radiation during handling.

HO or ECO? Simulate the irradiance of the BSL-03
The UV irradiation chamber simulator shows how the irradiance is distributed across the 64 × 49 cm sample tray of the BSL-03 and how strongly it decreases with the distance to the LED plane – a basis for choosing between the HO version with 220 mW/cm² and the ECO version with 110 mW/cm², and for the exposure time up to the target dose.

Spectra of the irradiation chamber BSL-03
The BSL-03 is available either fully equipped with a single wavelength or with two separately controlled LED groups. Fully equipped, the whole irradiance of up to 220 mW/cm² is available in one band; with two groups it is split. What all five bands have in common is what discharge lamps cannot offer: no infrared component and no secondary lines.
Irradiance, spectrum and LEDs
The chamber is available in two power levels. The values are the typical irradiances at an interior height of 30 mm; a shorter distance to the light source raises the irradiance further. They apply to a chamber fully populated with one LED type. With two wavelengths the chamber is populated half with each LED type, so half the irradiance is available per wavelength.
| Wavelength | ECO | HO |
|---|---|---|
| 365 nm | 60 mW/cm² | 120 mW/cm² |
| 385, 395, 405 nm | 100 mW/cm² | 200 mW/cm² |
| 450 nm | 110 mW/cm² | 220 mW/cm² |
The five wavelengths side by side, each normalised to its maximum. The half width is 10 to 20 nm and the peak wavelength matches the nominal wavelength to within ± 5 nm.

Equipment in detail
The chamber has a modular design and can therefore be adapted to different applications. These functions are always included:
 | Dose control The irradiance is measured continuously; the UV-MAT ends the irradiation once the set target dose is reached. The UV-MAT Touch offers the same functions but simplifies operation and documentation. |
 | Dimming and spectral adjustment The LEDs can be dimmed continuously from 2 % to 100 %. They are available in five wavelengths for different applications; as an option two wavelengths are available in one chamber and are controlled separately. |
 | Timer As an alternative to dose control the UV-MAT offers an adjustable timer for time-controlled irradiations between 0.01 s and 9999 h. |
 | Irradiation records Irradiations can be recorded with a PC. The UV-MAT Touch also records them to a USB stick without a PC. |

The UV-MAT Touch is operated through a high-resolution capacitive touchscreen. A Cortex ARM processor provides durability and the ability to update - new functions can be installed on site. The device and the PC software are compatible with Windows 10 and 11. Single- and multi-channel irradiations are shown numerically and graphically, together with oscillograms and the settings. Parameters are set directly on the device and are password protected.

Options
These options are available in addition to the standard equipment:
 | Inert gas box The removable inert gas boxes allow work under inert conditions - for example with adhesives that do not cure completely in the presence of oxygen. Separate gas inlets and outlets make it possible to measure the O₂ concentration at the gas outlet. |
 | Remote control option Complex, multi-stage irradiations - for example a pre-irradiation at low irradiance followed by a high-intensity irradiation - can be parameterised with the remote control option. Up to 30 dose- or time-controlled steps and pauses are possible. At the same time the irradiation is logged and stored on the PC. |
