FUSED QUARTZ OPTICAL FLATS IN CASE
- For visually checking the flatness of seals, gages and mating surfaces. Through means of interpreting light interference patterns or bands
- The double flat has both surfaces finished to tolerance but not necessarily parallel.
- Double flats provide longer service because wear is distributed over two surfaces.
- Coating is available and it aids readability when applied to one surface. Coating is of value on single-sided flats only.
