This fiber-coupled deuterium-halogen light source emits continuously from 200 nm to 2500 nm. The range 200 nm to 400 nm is mainly covered by the deuterium bulb, the range 400 nm to 2500 nm is mainly covered by the halogen bulb. The lamp operates exclusively in cw mode with a stability of < 1 mAU. The light source couples about 0.2 µW (200-400 nm) or 7 µW (400-2500 nm) into a 600 µm fiber.

The AvaLight-DHc is also equipped with a built-in TTL shutter, making dark current measurements very easy in combination with the AvaSoft.
