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.
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.

In addition to the technologies introduced here,
Tamron leverages various technologies for product development and to contribute to society.
In the future, Tamron plans to release the following technical information.
A coating technology that makes uniform vacuum deposition thickness at the peripheral areas and central areas even on a convex surface
Low film thickness with a high blocking, tight wavelength control and high steep edges
An anti-reflective coating technology for plastic lenses that offers improved anti-reflection performance and higher coating durability
We look forward to putting Tamron technologies to work within your business.
