We have recently improved the already industry leading accuracy of our Variable Optical Attenuators.

Our single mode variable attenuators are now calibrated with a linearity of 0.03 dB using an upgraded calibration system. We believe this is an industry leading capability. Our attenuators are calibrated at all points across the attenuation range, providing near-ideal performance for the user.  

Instruments with this level of tested performance will start appearing immediately.
