In need of more power than the AvaLight-DHc? The AvaLight-DH-S is Avantes’ most powerful deuterium halogen source. Like the DHc, the DH-S is also a combined deuterium and halogen light source, capable of transmitting light in the UV/VIS/NIR-range, but has 35 times more halogen output and up to 300 times more deuterium power. The source has a prominent 656 nm deuterium peak which can limit dynamic range (see Avalight-DH-S-BAL as an alternative). It includes a focusing lens assembly, to fully utilize the possibilities and size of your fiber.
The AvaLight-D-S is a deuterium light source only, making it a great option for measurements in the UV range, 190 to 400 nm. The AvaLight-D-S-DUV version starts even lower at 175 nm, for your deep-UV experiments. This version also offers twice the intensity at 200 nm.
The output of the AvaLight-DH-S is optimized for fibers or bundles up to 600 micrometers. For larger fibers the focal point is manually adjustable to optimize the light coupling into your fiber.
The AvaLight-D(H)-S features an integrated TTL-shutter and filter holder for filters of up to 50 x 50 x 5.0 mm.
