info@avantes.com | www.avantes.com | 153 Technical Data Wavelength range 200-2500 nm Attenuation 0-100% Iris aperture 0.0 – 12.0 mm Iris construction 2 x 5 leaves Fiber connection 2 SMA-905 connectors, incl. 2 COL-UV/VIS collimating lenses Material Black anodized aluminum Dimensions 60 x Ø 25 mm In-line Fiber-optic Attenuators ATT-INL-EXT For all UV-VIS-NIR applications and ATT- INL-EXT setups where light intensity has to be reduced, Avantes offers the inline fiber-optic attenuator (ATT-INL-EXT) and the direct attached fiber-optic attenuator (ATTDA). This device is an iris attenuator which controls light throughput to avoid detector saturation. The ATT-INL-EXT is coupled between two SMA terminated fiber-optic cables, whereas the ATT-DA can be connected directly to the light source. Both devices consist of two UV/VIS/NIR collimating lenses mounted on either side of an adjustable iris. The attenuation can be set from 0-100% and can be fixed with a set screw. Ordering Information ATT-INL-EXT • In-line Fiber-optic Attenuator, 0-100%, SMA connectors Technical Data Base Dimensions (L x W x H) 200 x 80 x 25 mm Fiber connection 2 x COL-UV/VIS, SMA connectors Optical path 10-160 mm Cuvette holder insert Minimal optical path 10 mm. Focal height 15 mm from base plate Overall dimensions (L x W x H) 200 x 96 x 62 mm Variable Pathlength Cuvette Holders For low absorption measurements and flow cell cuvettes, the CUV-VAR-UV/ VIS cuvette holder is the ideal solution. It features a variable, adjustable path length, ranging from 10-160 mm, ensuring maximum flexibility. It can be used as a standard cuvette holder with a 10 mm path length, as a filter holder with 2 mm path length or any path length up to 160 mm. This item is equipped with two COL-UV/VIS collimating lenses to support applications in the 200-2500 nm wavelength range.
