It is an optical filter that transmits near-infrared light and absorbs visible light.
This is an acrylic sheet made using the cell cast method, which absorbs visible light and transmits near-infrared light (670 to 1500 nm). (The transmission wavelength varies by part number.) It has a high smoothness comparable to glass while being easy to shape. Additionally, since it is not a coated type, there is no angle dependence. With low haze and low retardation, it is less likely to cause malfunctions even with high-precision sensors, making it suitable for active infrared sensors such as ToF sensors, 3D scanners, and biometric authentication. Functional enhancements can also be added through coatings such as hard coatings (6H to 8H), anti-reflective coatings, and water-repellent coatings. There are also automotive applications, including laser radar and driver monitoring systems. Samples are available. Please feel free to contact us.

Company information
Since our founding in 1947, we have utilized the characteristics of casting to manufacture high-precision cell-cast acrylic sheets with excellent optical properties, free from distortion and birefringence. We offer finely customized products unique to the cell-casting method, which is suitable for "small quantities and a wide variety." Pursuing the optical transparency, workability, colorability, and weather resistance of acrylic resin, we respond to customer needs under our corporate motto of "Creativity, Effort, Integrity, and Harmony," and we will continue to challenge ourselves in the development of higher quality products under the CLAREX brand.
