Master Test Plates
A pair of Test Plates constitutes the master standard for curvature and/or perfect flatness. Spherical Test Plates consist of a concave and convex pair, while Flat Test Plates are comprised of three flat plate units.
Production Test Plates
A set of Test Plates is used for inspection of lens elements at the production line. It is replicated from the master. As the pertinent surface sustains wear and tear and/or damage after a period of use, a precisely replicated replacement is produced from the very same master.
TAMRON's Test Plates are produced in conformity with tolerances as specified below:
|Spherical Test Plates||1mm～150mm||200mm以下||±0.02％|
|Flat Test Plates||5mm～300mm||∞|
*Product curvature values were found at TAMRON.
*Let us know in advance if you will be confirming curvature precision at your business after product delivery.
