Hot and cold mirrors provide an easy, straightforward way to funnel unwanted heat out of a system. They are used in many different applications where heat generation or the presence of extra IR energy might pose a problem.

A UV cold mirror is another type of mirror that reflects UV light while transmitting both infrared and visible light. UV cold mirrors are used in processes where UV light is essential, and the presence of other light would be problematic, such as in the photopolymerization of inks, dyes, and adhesives, or in semiconductor chip manufacturing.

Both mirrors are often used for the same purpose: protecting heat-sensitive equipment from potentially damaging IR radiation. However, since hot mirrors transmit visible light and reflect IR, and cold mirrors reflect visible light while transmitting IR, their placement in a system will differ.

Another use of hot and cold mirrors is to overlay two beams. One beam is reflected off the mirror while the other is transmitted through the surface, allowing the mirror to be tilted so that both beams travel along the same path. This is particularly important in surgical lasers, where mirrors are arranged so that a cool, visible laser beam travels along the same path as the invisible hot infrared laser used for cutting tissue. This setup enables the surgeon to see what they are doing.

At Avantier, we produce custom cold and hot mirrors with a wide range of parameters. We can optimize these mirrors for the desired angle of incidence (0° or 45° are the most common options) as well as for your desired wavelengths and system configurations. If you are looking for cold and hot mirrors for imaging systems, laser systems, or other needs, our designers can work with you to determine what works best for your application. Call us today to set up your initial consultation or place a custom order.

A hot mirror will be placed in the beam path where heat should be removed, usually just before the components that need protection. Visible light will pass through to the heat-sensitive components, while infrared light is effectively blocked.

Diffraction gratings are very important in hyperspectral imaging. Their desired diffraction efficiency is dictated by the sensitivity of the detector in the spectral band of interest and the luminance of the scene to be observed. If the desired diffraction efficiency curve is established in this spectral band of interest, the remaining work is to design a diffraction grating that meets this demand. This paper is concerned with blazed gratings in reflection, and the geometry of the grating will therefore depend on this reference curve, the spectral band, and the optimization order. The simplest form is a grating with a uniform profile that is optimized at a single-blaze wavelength. It is a monoblaze grating. When such grating cannot meet the requirements in terms of diffraction efficiency, a multiblaze grating optimized at several blaze wavelengths is required. The objective of this paper is to propose a method of optimization of this multiblaze grating, i.e., how to find the number of blaze wavelengths necessary as well as their value to answer the requirements in term of diffraction efficiency.

A cold mirror efficiently transmits infrared wavelengths while reflecting all visible light, whereas a hot mirror reflects infrared wavelengths while transmitting visible light. Both mirrors are used to filter unwanted heat or energy out of a system. They typically use multi-layered dielectric coatings to reflect and transmit light and can be designed for specific wavelength ranges.  At Avantier, we produce custom cold and hot mirrors for a wide variety of applications.

A hot mirror will be used as a folding mirror in the beam path, as it transmits all the infrared light, effectively eliminating it from the optical system while reflecting visible light.
