The 884-IGR OD3 Attenuator is a stackable OD3 attenuator that can be mounted to an 818-IG series detector to attenuate the input beam. It is the RoHS compliant version of legacy 883-IG and 884-IG. The clear aperture is 10.3 mm. Note that one attenuator is already included and calibrated in the 818-IG/DB detector. If you already own an 818-IG series detector and want to have the attenuator calibrated together with the detector, you must contact Newport service department.
