Test Plates

The lens test plate is a crucial reference for all optical lenses. Achieving the ultra-high precision needed for these test plates goes beyond what automated grinding machines can accomplish. Instead, traditional techniques using Oscar-type grinding machines are required to meet these exacting standards.

Tamron’s dedication to craftsmanship is evident in our meticulous testing of both spherical and flat configurations. With years of expertise, this commitment shines through in the extensive range of test plates we produce, demonstrating the rigorous quality control that defines our optical element manufacturing processes.
