884 Series OD3 attenuators can be purchased separately to extend the optical dynamic range of the photodiode sensor heads by up to three decades. The 10 mm clear aperture with the cross hair helps the detector alignment to the input optical beam. They are not spectrally calibrated.
- Compatible with 818 Series photodiode sensors
- OD3 for up to three decades of additional dynamic range

OD3 Attenuators
The optional 884 Series OD3 attenuators can be purchased separately to extend the optical dynamic range of the photodiode sensor heads by about 1000 times. The 10 mm clear aperture with the cross hair helps the detector alignment to the input optical beam. They are not spectrally calibrated.
