It is possible to efficiently transmit light while removing wavelengths that contribute to heat from the light source. It is ideal for medical lighting devices (such as dental mirrors).
【1】Are you facing any of these issues? ◆ I want to prevent the temperature from rising due to near-infrared light emitted from the light source. ◆ The device itself is getting hot, and I want to do something about it. ◆ Is it possible to reflect visible light while allowing near-infrared (NIR) to pass through? ◆ Can the wavelength range of the mirror be customized? 【2】What is a cold mirror? A cold mirror is a filter that transmits near-infrared light while reflecting visible light. By forming a dielectric multilayer film, it can efficiently transmit thermal radiation without absorption, removing wavelengths that contribute to heat contained in the light source. Additionally, due to the excellent heat resistance and weather resistance of the dielectric multilayer film, it plays a role in stabilizing products that incorporate the filter. Typical applications include liquid crystal projectors, medical lighting fixtures, and dental mirrors that you may have seen on dental chairs. It has the performance of a mirror while featuring a special coating that allows near-infrared wavelengths to pass through to prevent temperature rise in the irradiated area.

basic information
◆Design and customization are possible in the desired wavelength range We can design and deposit (coat) according to the wavelength range requested by the customer. Control in both the transmission range and the blocking range, as well as the angle of incidence, are important factors. We will design according to the characteristics of the substrate and the customer's requirements, so please provide the type of substrate and wavelength range when making inquiries. ◆Component support is also available We can handle everything from substrate procurement to film deposition. It is also possible to cut to any shape and ship as components. However, we will need detailed drawings. ◆Measuring instruments We will always attach a measurement chart upon shipment, so please rest assured. ◆Clean room compliance The working environment is maintained in a clean room with the necessary cleanliness for each process, from film deposition to inspection, ensuring a thorough system against minor film defects (such as foreign substances in the film). ◆Safety and peace of mind We do not use any substances harmful to the human body. We can provide data for various environmental surveys (such as Chemsherpa).
