It is a mirror that reflects light of a specific wavelength and transmits light of other wavelengths.

【1】Are you facing any of these issues? ◆ Is it possible to maintain a uniform reflectance for multiple wavelengths? ◆ Is it manageable if the reflectance decreases at specific wavelengths? ◆ Is color reproducibility achievable? ◆ Is there no problem with the stability of optical performance due to temperature changes or variations in environmental conditions? ◆ Is it possible to ship parts with a special shape? 【2】What is a dichroic mirror? A dichroic mirror is a mirror that reflects light of specific wavelengths while allowing other wavelengths to pass through. It consists of multiple layers, each with different optical properties. This characteristic allows for the effective separation, combination, or blocking of light at different wavelengths. 【3】Features of dichroic mirrors - Spectral separation Dichroic mirrors are used for spectral separation by selecting and reflecting or transmitting light of specific wavelengths from incident light. For example, they are used in optical devices that extract and detect light of specific wavelengths. - Light filtering They are used as filters to selectively remove light of specific wavelengths. This allows for the removal of unwanted light, enabling only the desired wavelengths to pass through.

ND stands for "Neutral Density," which is a filter used to adjust the light transmission rate.

【1】Are you facing any of these issues? ◆ I want to address concerns about flares and ghosts. ◆ Is it possible to adjust the transmittance with a custom setting? ◆ I am looking for a filter for adjusting laser equipment. ◆ The shape is special; can it be shipped as a part? 【2】What is an ND filter? ND stands for "Neutral Density," which is a filter used to adjust the transmittance of light. It is attached to the lens to reduce the amount of light entering from outside. It is an essential optical component for controlling shutter speed and aperture in bright environments when taking photographs with cameras, in order to achieve the appropriate exposure. 【3】Design and customization available for your desired wavelength range At Adachi New Industries, we can design and coat (film) according to your desired wavelength range.

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.

It is a filter that efficiently cuts (reflects) short-wavelength UV (ultraviolet) light while allowing visible light to pass through.

What is a UV cut filter (ultraviolet cut filter)? It is a filter that cuts ultraviolet (UV) light while allowing visible light to pass through. In digital cameras, it is used to reduce chromatic aberration, and in liquid crystal projectors, it is used to prevent the degradation of liquid crystals and other optical components caused by the light from lamps (such as high-pressure mercury lamps), with the aim of cutting unnecessary ultraviolet light. Are you facing any of these issues? ◆ Is it possible to cut only the wavelength of ultraviolet light? ◆ Can a UV cut filter for projectors be coated? ◆ I would like to consult about the degradation of optical components. ◆ I would like to consult about filters that minimize the impact on the human body. ◆ Is it possible to custom adjust the wavelength range that I want to transmit?

It is a dielectric multilayer film filter that transmits visible light and reflects near-infrared light.

It is used as a near-infrared cut filter that adversely affects CCD devices such as video cameras. The optical characteristics, such as the wavelength position with a transmittance of 50%, transmittance, and cut wavelength band, can be set arbitrarily. (Are you facing such challenges?) Is it possible to cut only the wavelength of near-infrared light? I want to allow visible light to pass while blocking IR wavelengths. I want to suppress light that causes noise and increase the sensitivity of the sensor. Can the wavelength range I want to transmit be custom adjusted? Is it possible to process it to chip size?
