Provide transparency & maintain device functionality

Transparent Heaters

Transparent heaters prevent dew condensation, accumulation of snowfall and frost to enhance the visibility of cameras, as well as windows and other objects that require high transparency

Overview

Transparent heaters take advantage of Geomatec's thin-film technology and know how to prevent dew condensation, accumulation of snowfall and frost on objects that require high transparency, such as cameras and windows. They are perfect for environments that require temperature control.

  • Point1Maintain visibility by eliminating dew condensation, accumulation of snowfall and frost
  • Point2Maintaining consistent temperature across the entire surface
  • Point3Clear visibility with a maximum transmittance of over 98%*1
  • Point4Applicable to not only flat surfaces but a variety of other forms, including curved and semi-circular surfaces
  • Point5Freely customizable to meet conditions such as maximum generated temperatures of 500℃*2

*1When non-alkali glass is used as a substrate material and anti-reflective coating is applied to both sides of the substrate after heater formation (550 nm wavelengths)

*2When using quartz as a substrate

Before & After

An image comparing objects in the same environment with and without transparent heaters applied. Take a look at the clear difference and tangible performance levels.

Evenly heats the entire surface to eliminate visibility flaws

The image on the left is normal glass, while the image on the right is glass with a transparent heater applied and power turned on. This video shows steam blown on the glass from an iron to compare condensation levels. The glass with the transparent heater applied clouds less easily, prevents dew condensation, and maintains clear visibility.

Features & Strengths

Point1 Maintain visibility by eliminating dew condensation, accumulation of snowfall and frost

A transparent heater can be applied to cameras, train windows, and other transparent parts. They are effective at preventing dew condensation, accumulation of snowfall and frost. This helps maintain superior visibility.

  • Visibility clears within seconds after turning the transparent heater on

Point2 Maintaining consistent temperature across the entire surface

Transparent heaters maintain a consistent level of heat over the entire object, making them perfect for preserving visibility when transparency is required. They can also be used for the heating stage of microscopes and in medical or biological experiments.

  • With a standard electric heater: heat is generated through wires, resulting in uneven temperatures
  • With a transparent heater: even heat generated across the entire surface

Point3 Clear visibility with a maximum transmittance of more than 98%*1

Transparent heaters can be applied to entire surface of glass and are optimum for use in environments and locations that require transparency. With transparent conductive and ITO films for displays or touch screens, Geomatec has utilized the knowledge gained as a leader in transparency technology to achieve high transmittance rates.

  • Glass only: transmittance of 92%*
  • Glass+Transparent heaters: transmittance of 89%*
  • Glass + Transparent heater + Anti-reflective coatings (both sides): transmittance of 98%*

*With wavelengths of 550 nm

Point4 Applicable to not only flat surfaces but a variety of other forms, including curved and domed surfaces

For materials, they can be used with transparent resins, such as glass and poly-carbonate. In addition to flat surfaces, Geomatec can also apply films to curved, domed, and cylindrical (inner and outer) surfaces, as well as other unique shapes, upon consultation. Applicable to a diverse range of needs.

  • Example of transparent heater applied to domed covers
  • Thermographic images: even heating of domed surfaces

Point5 Freely customizable to meet conditions such as maximum generated temperatures of 500℃*2

Specifications can be adjusted to match different power sources, usage environments, and heat levels. We also accept requests for customization of electrodes, lead wiring and insulation treatments. In addition, high-performance thin films such as water repellent coatings, hydrophilic coatings and thin thermocouples (temperature sensors) can be combined.

Structures & Mechanisms

Transparent, but heated through electricity

By applying the transparent conductive films and ITO films that are Geomatec's specialty to substrate materials like glass and attaching metal electrodes to conduct electricity, it is possible to create special materials that are transparent and yet generate heat.
