NEWPORT 9809NF kinematic mirror + 9954 pedestal + 1" OD filter Description: nice lens kinematic mount kit removed from High School laser lab. Measures for mount: https://www.newport.com/p/9809NF. For pedestal: https://www.newport.com/p/9954. Bottom thread is imperial 8-32" (similar to M4 but bigger pitch). Filter seems to attenuate light to around 12,5% (attenuates light by 8 power... enters "100", outputs "12,5"). I am not sure, but it could be FSR-OD90 or FSR-OD70 as per Newport catalog. Weights 375gr. Condition: normal usage marks. Nice working condition. Filter condition is like-new. Note: these items have been de-greased, cleaned, re-greased (with special oil, better than original grease) and checked for missing or damaged parts. Then tested and verified ok. Good functioning is garanteed. Issues: some marks of normal usage here and there.
