Elcometer offers a comprehensive range of vacuum tables to provide an ideal surface for manual application of films on test charts or samples and is available in two formats:
- The Elcometer 4900 - made of perforated aluminium, keeps a wider range of test pieces absolutely flat (2.3µm variation over a 100mm length), including glass, plastic sheets, contrast charts etc.
The perforated version is suitable for thicker, more substantial test pieces. The channel version is suitable for thinner materials such as plastics and films which may distort under the perforated version method.
All beds are engineered to be flat and precise with little variation for "perfect" flatness. Both Elcometer standard tables, channelled and perforated vacuum tables are 5 times flatter than glass.
This Perforated table has one sample size setting, 210 x 297mm (8.3" x 11.7").
