In addition to typical applications such as dermatology and healthcare, there are a number of other uses for UVB wavelengths (280 - 315 nm); for example:

• Analytics
• Biotechnology
• UV curing
• UV printing

LASER COMPONENTS offers UVB LEDs with peak wavelengths of 295 nm and 308 nm. A large selection of output powers is also available here.

The technical development of UV sources is advancing rapidly. Our experts will be happy to keep you up to date on the current state of the industry. In a personal conversation, they will also inform you about which innovations to expect in the near future.

In addition to the LEDs, we also supply the SiC detectors for monitoring the UVB LEDs and the appropriate filters for all combinations of the various powers, wavelengths, and applications.

For many years, UV curing and UV printing have been using UVA LEDs in addition to the bulgy mercury vapour lamps. The photoinitiators used in these processes are developed to react selectively to these wavelengths. Additional UVB radiation at 280 - 300 nm can enhance the curing effect.

UVB LEDs with a wavelength of 295 nm are available from LASER COMPONENTS with an optical power of 3.3 mW, 15 mW, 21 mW, 50 mW or 110 mW per chip.

Excimer lamps or lasers with emission wavelengths around 308 nm have been used in dermatology for decades. Now, small, handy UVB LEDs with a form factor of mere 3.5 × 3.5 mm² and a maximum heat generation of 3 W per chip open up new possibilities and geometries. It goes without saying that this is also the case in many other applications such as analytics.

Depending on the chip size, you can get these LEDs with an optical power of 3.3 mW, 15 mW, 21 mW, 50 mW or 110 mW per chip.
