Esco PN:
  • $ 000

Esco Optics reflective wedge witness samples are precision polished on one side normal to the edge. The scratch dig is 60-40. The flatness of normal side is < 2 waves @ 633nm at 90% CA. Both edges are chamfered. The second side has a ground face at 8 degrees +\-30 arc min. The diameter is 25.40mm and the thickness is thin edge is 2.0mm +\-0.20. 

All of our witness samples are melt lot controlled and individual melt data is available on request. The refractive index values listed are representative of nd at 587nm.
