Anti-Newton Glass

When two flat optical surfaces are in close proximity interference effects associated with residual Fresnel reflection can be seen, these are a special case of Newton’s Rings.  Anti-Newton glass sheets are lightly etched to deform the surface enough to prevent this but with minimal effect on image quality.  Although we stock anti-Newton glass in standard sizes we can offer custom anti-Newton material to bespoke sizes.  Anti-Newton material is often used in scanners and film enlargers  for scanning photography negatives etc without seeing the interference rings (Newton`s rings)
