Heat Control – Hot & Cold Mirrors
Cold mirrors reflect UV or the visible & transmit the infrared (heat) at temperatures to ≥400°C. Hot mirrors or shortwave pass filters (SWP) reflect the infrared & separate it from an application. ITO heated windows heat to an ambient temperature.
Cold Mirrors
Abrisa Technologies provides a line of cold mirrors that reflect Ultra-Violet (UV) or visible energy while transmitting the infrared (heat energy). Cold mirror coatings are vacuum deposited multi-layer dielectric films that can operate in temperatures of ≥400°C and are durable and easy-to-clean. The glass substrate used for our cold mirrors is SCHOTT Borofloat®, a versatile borosilicate glass substrate with excellent thermal properties. Thickness availability is 1.1mm, and 3.3mm. Cold mirror sizes are available up to 27” diameter. Custom sizes and thicknesses and specialty designs are available upon request.
Hot Mirrors
Abrisa Technologies can supply hot mirrors or shortwave pass filters (SWP) for heat control applications. For hot mirrors, a thin film coating is applied to a glass substrate, such as soda-lime or borosilicate, in order to reflect infrared radiation either as a means to harness the reflected wavelengths for an application or remove them from an application. Simplified, a hot mirror will separate visible light from heat. Hot mirrors are typically provided on a cut to order basis in thicknesses of 1.1 mm, and 3.3mm and in diameters up to 27”. Custom sizes and thicknesses and specialty designs are available upon request.
Indium Tin Oxide (ITO) Heater Coatings
Abrisa Technologies’ Transparent Conductive Heaters incorporate coatings of Indium Tin Oxide (ITO), Index-Matched Indium Tin Oxide (IMITO) or Indium Molyb-denum Oxide (IMO) and are ideal window and display glass solutions when anti-fogging or de-icing, and high throughput and clarity are needed to maintain unobscured viewing and optical sensing in cold climates. The coatings deliver the high uniformity and low scatter performance needed to preserve high resolution digital imaging, sensing or display outputs while maintaining high throughput efficiency and clari-ty. Our solutions incorporate key heating attributes that can be tailored for specific needs, including design considerations for anti-reflective properties for visible, NIR, SWIR, and IR, optimization to air or index matched for bonding, and delivery of color neutral performance in transmission, reflection, or both.
