4"x5" Anti-Newton glass fits the DeVere 504 4"x5" master negative carrier, and the 4"x5" adapters of most DeVere large format enlargers. Use anti-Newton glass in place of regular carrier glass in the top of the carrier to prevent Newton rings. Anti-Newton glass has a slight texture to it which prevents the smooth film base from adhering to the glass.
For negative carrier information for specific De Vere enlargers, please refer to our DeVere Enlarger Guide.
