High reflectivity and high transmittance dichroic mirror
The dichroic mirror is designed for an incident angle of 45°. It allows transmission on the longer wavelength side of a specific wavelength while reflecting the shorter wavelength side, enabling spectral separation.
A technology that deposits molecules onto a substrate surface to form a thin film! An explanation of vacuum deposition!
Let me introduce the mechanism of vapor deposition. "Vacuum vapor deposition" is a technique that involves heating and evaporating metals, oxides, etc., using an electron gun or similar device in a vacuum of less than 1.0E-3 Pa, and depositing the resulting molecules onto the surface of a substrate to form a thin film. Kawai Optical Co., Ltd. has been advancing its unique research and development in vacuum vapor deposition technology. To accurately respond to customer demands, all management and employees work together, sharing information to focus on creating high-quality products with stable safety. Our website also explains the "mechanism of sputtering" and "mechanism of optical films." For more details, please refer to the related links below.

Achieves a high reflectance of 98% for specific colors, while transmitting over 90% for the remaining colors.
Dichroic mirrors, primarily used for color separation and synthesis purposes, are designed at an incident angle of 45°, unlike dichroic filters, and obtain the specified color as reflected light rather than transmitted light. Additionally, there is an advantage in that the transmitted light (colors other than the specified color) can also be effectively utilized. Edmund Optics' dichroic mirrors achieve a high reflectivity level of 98% in specific wavelength ranges, with the remaining colors transmitting over 90%. ■ Reflects the specified color while transmitting the rest of the visible spectrum ■ Ideal for color separation applications ■ Made with precision N-BK7 glass substrates *You can download the catalog from Edmund Optics Japan, which features this product, from the link below.
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.
It is possible to separate and synthesize the three primary colors from white light! Colors can be obtained through vertical incidence!
The "dichroic mirror/filter" is a mirror (filter) that reflects (transmits) light of specific wavelengths while transmitting (reflecting) other light. It is possible to separate and synthesize the three primary colors of blue (B), green (G), and red (R) from white light. Additionally, colors such as yellow (Y), magenta (M), and cyan (C) can be obtained through vertical incidence with the filter. 【Features】 ■ Reflects (transmits) light of specific wavelengths while transmitting (reflecting) other light ■ Capable of separating and synthesizing the three primary colors of blue (B), green (G), and red (R) from white light ■ Colors can be obtained through vertical incidence ・Yellow (Y), Magenta (M), Cyan (C) *For more details, please refer to the PDF document or feel free to contact us.
