Highly reflective, highly resistant mirror coatings

Metallic Mirror & High Reflectivity (HR) Coatings

Achieving greater reflectance through optical thin-film technology, such as the coating of glass and resin substrate surfaces with silver, aluminum and other reflective metals

Overview

Since its founding, Geomatec has spent a half century creating metallic mirror coatings (optical mirrors). When it comes to the manufacture of mirrors that require high reflectance and superior optical characteristics, such as those used in video projectors, liquid crystal displays, astronomical telescopes, and other products, Geomatec has extensive experience with metallic mirror and high reflectivity (HR) coatings, so please feel free to seek our advice.

Features & Strengths

Point1 Depending on your needs, we will propose a reflective coating that utilizes the characteristics of aluminum, silver, gold, or other metals

Aluminum (Al) is popular for use in mirrors of visible and infrared varieties, while alloys exist of gold (Au) and silver (Ag) that improve durability and secondary workability. Geomatec has extensive experience with metallic mirror and high reflectivity (HR) coatings, enabling us to propose a variety of metals that meet your objectives.

Point2 Customization of optical or electrical characteristics, or of durability within specific usage environments, is possible

By pairing a variety of metallic mirror and high reflectivity (HR) coatings (dielectric multilayer films), optical characteristics such as the wavelengths and reflectance of reflected light, as well as incident angle dependence, can be adjusted. You can also increase heat resistance with protective films, elevate wear resistance, and choose different metals to adjust electrical characteristics. Customization allows us to skillfully control the balance of functions necessary for our customers' products.

Functions & Mechanisms

Different coatings can be used to create the optimum mirror for your application needs

Metallic mirror coatings are formed by applying metal films with a high rate of reflectance to glass and resin substrates. High reflectivity (HR) coatings are metallic mirror coatings with dielectric multilayer film applied to achieve a greater reflectance rate and necessary optical features.

  • Example structure: metallic mirror coatings
  • Example structure: high reflectivity (HR) coatings

With high reflectivity (HR) coatings, the reflectance rate is dependent on the incidence angle of light and changes easily. Since they are well suited to applications that involve straight incidence of light, the optimum structure will change, depending on the objective.

When it comes to the manufacture of optimum mirrors for customers, Geomatec has created several metallic mirror coatings and high reflectivity (HR) coatings, developing a wealth of knowledge and achieving firm results.
