Coating and Filter Technology

To fully derive a lens performance in accordance to various purposes, an optimal coating needs to be applied in addition to optical lens design technology.
By applying a coating on the lens surface various effects and functions can be achieved such as optical performance enhancement and surface protection.
Tamron conducts lens and coating development for various applications, for instance, surface protection for photographic lens, durability enhancement for automotive camera, and surveillance camera.
Moreover, Tamron is holding a uniform coating technology for wide curved surfaces on wide-angle or fish-eye lenses. Recently, to achieve a coating technology suitable new fields, Tamron is developing a filter/coating technology capable of precisely transmitting a specific wavelength for medical or fluorescence imaging with laser.

Fluorine Coating

Wiping durability enhancement

Wiping durability enhancement

Lenses used in optical devices often touched by people or installed in devices facing adverse conditions need to be cleaned by wiping with solvent. If needed to be repeatedly cleaned coatings applied to the lens, such as an anti-reflection coating, will wear-off. Fluorine coating is the solution so that dust, moisture, oil (sebum) on the lens surface can be easily removed.

Tamron’s fluorine coating is a high water repellent and antifouling, at the same time achieving anti-reflection. Tamron delivers a lens with wiping durability enhancement contributing to save of labor for maintenance, which can be used in a wide variety of usages.
