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.

Dichroic filters are commonly used in machine vision applications, primarily for color separation and contrast enhancement. Please note that this product separates colors using dielectric multilayers, so if light enters at an angle different from the designed incident angle, the specified characteristics may not be obtained. Therefore, please exercise caution when using it. Edmund Optics offers a total of six filters in three additive colors (red, green, blue) and three subtractive colors (cyan, magenta, yellow), available in various sizes. We also provide sets of additive and subtractive filters, each available in different sizes. Additionally, we offer preset filter wheels with the six filters fixed in advance. ■ High-saturation dielectric multilayer filters ■ Three additive filters and three subtractive filters ■ Available for individual sale and as sets ■ Precision glass substrate *You can download the catalog of Edmund Optics Japan from the link below.

This is a dielectric multilayer film filter that cuts infrared (IR) light and transmits cold light (visible light). It is frequently used in applications where it is necessary to avoid the effects of heat—such as in black-and-white cameras—by inserting it in front of the imaging sensor to prevent thermal light from entering the sensor. The substrate surface is coated with a dielectric multilayer film that functions as an IR cut, designed for an incident angle of 0° (collimated light). Borofloat glass, which has excellent heat resistance, is used for the substrate. Additionally, an anti-reflective coating is applied to the backside to prevent ghost image generation. ■ Cut-off wavelength of 710nm ■ Options for circular and rectangular shapes ■ Available in various sizes *The catalog from Edmund Optics Japan can be downloaded from the link below.
