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. Key Features: Combined Deuterium-Halogen Light Source UV-VIS-NIR Range Deep-UV Option High Optical Power Integrated TTL-Shutter Wavelength Range: 175 to 2500 nm Warm-up Time: 20, 30 min Lamp Power: 5, 78 W Maximum Drift: ±0.1, ±0.5%/h Noise (AU): 2x10-5, 10-4 Colour Temperature (Halogen Lamp): 3,000 K Optical Power: 11, 43 µW (200 µm Fiber), 72, 239 µW (600 µm Fiber), 206, 354 µW (1000 µm Fiber) Lamp Lifetime: 1000, 2000 h Power Supply: 100 to 240 VAC, 50/60 Hz Dimensions: 315 x 165 x 140 mm Applications: Spectroscopy and Measurements in the Deep-UV/UV/VIS/NIR Range

200-1099 nm; Calibration Repeatability ±1.0%; Calibration Relative Uncertainty ±9%-±10%; Bulb Output 5, 80 µW cm-2 nm-1; Power Supply 100-240 VAC Calibrating your spectrometer has never been easier: Avantes’ AvaLight-DH-CAL series are NIST-traceable, calibrated light sources to measure absolute spectral intensity with. For calibrations in the ultraviolet (UV) and visible (VIS) range (200 to 1099 nm), the AvaLight-DH-CAL is the best solution. This source can be used with all AvaSpec spectrometers to calibrate for absolute spectral intensity. It is supplied with a built-in diffuser, a cosine corrector (CC-VIS/NIR) with SMA adapter and a CD-ROM containing the calibration files in ASCII format. Two calibration files are included: one for irradiance calibration over the full range (200 to 1099 nm) and one over the visible and near infrared range (350 to 1099 nm). For the first file, both the deuterium and the halogen bulb should be used during calibration. The second file is to be used with only the halogen light. The halogen-only spectrum provides a smoother black-body calibration spectrum for the longer wavelengths. The calibration files can be imported in the AvaSoft-IRRAD application software for intensity calibration, which turns your spectrometer into a spectroradiometer. For a more balanced spectrum across the 200 to 1100 nm range, Avantes offers the AvaLight-DH-BAL-CAL light source. For ultraviolet range calibration only (200 to 400 nm), the AvaLight-D-CAL is the right choice. The AvaLight-DH-CAL-ISPxx is a special version of these calibrated light sources, meant to facilitate coupling of the AvaSphere-xx-IRRAD integrating spheres (xx is 30, 50 or 80) to the light source. The AvaLight-DH-CAL, AvaLight-DH-BAL-CAL and AvaLight-D-BAL-CAL all include a power supply.

Balanced Power; 200-2500 nm; Drift <±0.1, <±0.5%/h; Optical Power 6-448 µW; Halogen Lamp Colour Temperature 3,000 K; Power Supply 100-240 VAC, 50/60 Hz Avantes’ AvaLight-DH-S is a powerful light source, but, like any unbalanced deuterium-halogen source, it does have a very dominant alpha peak at 656 nm. This is why Avantes developed the DH-S-BAL, in which this peak is drastically reduced by a dichroic filter. This means less power, but an increase in the dynamic range of a factor 20. The light source delivers a continuous spectrum with high efficiency. The highest stability is in the ultraviolet (UV), visible (VIS) and near-infrared (NIR) range, from 200 to 2500 nm. An integrated TTL-shutter and filter holder for filters of up to 50 x 50 x 5.0 mm are included. The filter holder can be easily replaced by a direct-attach cuvette holder CUV-DA-DHS, useful for fluorescence or absorbance measurements. The TTL-shutter can be controlled from any AvaSpec spectrometer, which means the auto-save-dark option in AvaSoft software can be used. Connection to the fiber is done through an SMA-905 connector, which features an adjustable focusing lens assembly. This ensures you have the maximum possible power into your fiber. For all deuterium light sources, solarization resistant fibers (-SR) are recommended. The output of the AvaLight-DH-S-BAL is optimized for fibers or bundles up to 1500 µm. Key Features: Balanced Power Light Source Combined Deuterium-Halogen Light Source Wide Wavelength Spectrum in the UV-VIS-NIR Range: 200 to 2500 nm Integrated TTL Shutter High Efficiency Increased Dynamic Range Warm-up Time: 20, 30 min Lamp Power: 5, 78 W Maximum Drift: ±0.1, ±0.5%/h Noise (AU): 2x10-5, 10-4 Colour Temperature (Halogen Lamp): 3,000 K Optical Power: 6, 17 µW (200 µm Fiber), 33, 160 µW (600 µm Fiber), 90, 448 µW (1000 µm Fiber) Lamp Lifetime: 1000, 2000 h Power Supply: 100 to 240 VAC, 50/60 Hz Dimensions: 315 x 165 x 140 mm Applications: Spectroscopy and Measurements With Balanced Optical Power in the UV/VIS/NIR Range
