Hot and cold mirrors are both specialized dielectric mirrors which are used for heat control; to filter unwanted energy from a light source. A cold mirror will reflect 90% of the visible light spectrum while efficiently transmitting (and thus removing from the site of interest) infrared wavelengths. A hot mirror will reflect 90% of infrared and near infrared light, and transmit a large portion of visible light (up to 80%). Shanghai Optics can manufacture custom hot and cold mirrors for any angle of incidence desired, from 0 to 45°.

Dielectric mirrors, such as hot and cold mirrors, are specifically designed to regulate heat by filtering out undesired energy from a light source. Cold mirrors are capable of reflecting 90% of visible light spectrum and effectively transmitting infrared wavelengths, thereby removing them from the area of interest. On the other hand, hot mirrors can reflect 90% of infrared and near-infrared light while transmitting a significant portion of visible light (up to 80%). Avantier has the capability to produce tailor-made hot and cold mirrors for any angle of incidence, ranging from 0 to 45°.

Hotmirror

Knight Optical can provide hot mirrors from stock in 25 mm to 50 mm diameters or 25 mm × 25 mm to 100 mm × 100 mm squares, however these can be cut to custom dimensions with a quick turnaround. Hot mirrors reflect IR whilst transmitting visible light. These mirrors are an alternative to our KG1 heat filters which absorbs the infrared light rather than reflecting it.

In contrast to dichroic mirrors, which usually have specified optical properties only for two narrow wavelength regions, hot mirrors have such properties (although with less strict specifications) for much broader wavelength regions.

Particularly for image projectors which contain some kind of incandescent lamp (e.g. a halogen lamp) as light source for the illumination, there can be a substantial heat load on the optical system. This is essentially because not only the desired visible light is generated, but also the more substantial power in the infrared. That infrared light may be absorbed in optical glasses, for example, heat them up, and cause various kinds of detrimental effects, such as mechanical stress and deformations which cause optical aberrations.

Hot mirrors are realized as dielectric mirrors. Such a mirror should ideally reflect all light in the near and mid infrared. However, such a large reflection bandwidth is hard to achieve, since the refractive index contrast of the usual coating materials is relatively small. Also, the common materials eventually get absorbing for long enough wavelengths. Therefore, part of the heat protection may be accomplished by absorbing infrared light; a high reflectivity is achieved mostly in the near infrared, e.g. only up to wavelengths around 1.3 μm or 1.5 μm.

In order to eliminate or at least mitigate that problem, special mirrors (heat control filters) have been developed which can work in two different ways as optical filters for removing infrared light:

The infrared absorption in the mirror substrate may lead to some thermal effects in the mirror, which may to some extent degrade the system performance. Such effects can be minimized by using a substrate glass with particularly good thermal resistance, including relatively small thermal expansion. For example, borosilicate glasses and fused silica are suitable for that purpose. Soda–lime glasses are sufficient only for lower powers.

As is common for dielectric mirrors, the reflection spectrum is optimized for a certain angle of incidence – for example, for normal incidence or for 45° – and the performance can be substantially worse for other incidence angles.

Edmund Optics offers various specialty mirrors, including hot mirrors which reflect 90% of NIR and IR light. We also have extended hot mirrors with improved NIR reflectance and high performance versions with an optimized multi-layer dielectric coating.
