AvaLight-D(H)-S Deuterium-Halogen Light Sources
Product information "AvaLight-D(H)-S Deuterium-Halogen Light Sources"
175-2500 nm; Drift <±0.1, <±0.5%/h; Optical Power 11-354 µW; Halogen Lamp Colour Temperature 3,000 K; Power Supply 100-240 VAC, 50/60 Hz
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-D(H)-S light source is optimized for fibers or bundles up to 600 µm. For larger fibers, the focal point is manually adjustable to optimize the light coupling into your fiber. The AvaLight-D(H)-S also features an integrated TTL-shutter and filter holder for filters of up to 50 x 50 x 5.0 mm.
