UV-Vis-NIR Rear Beam Attenuator (RBA)
The rear beam attenuator (RBA) provides continuous attenuation of the UV-Vis-NIR spectrophotometer’s reference beam to extend its dynamic range and reduce noise at higher absorption levels. The motorized accessory mounts on the sample compartment wall and is driven from the Cary WinUV software.
