Labsphere Launches Newest Durable Reflectance Coatings

Labsphere, Inc. has released its newest diffuse reflectance coating, Permaflect, to augment the well-established product line of Diffuse Reflectance Materials and Coatings which includes award-winning Spectralon®, Spectraflect®, and Infragold®. Labsphere provides innovative solutions for a wide range of applications including LED/SSL lighting, remote sensing, imager/consumer camera, automotive, defense and security, health and biomedical optics to both Production and Research environments.

Labsphere’s Permaflect proprietary near Lambertian white and grey reflectance coatings are engineered for use in applications where hostile environments, weathering, and wear may affect typical reflectance coatings. Reflectances range from 5% to 94%.

Greg McKee, Chief Technologist at Labsphere stated: “From disposable references for medical instrumentation to image sensor baseline targets, the applications for Labsphere‘s tailorable diffuse reflectance coatings are unlimited and beyond compare.”

In addition to providing Permaflect as an option for coated components, Labsphere offers Permaflect Diffuse Reflectance Targets in a wide range of sizes. These targets are a superior option to paper and paint in a broad range of ambient conditions. “Permaflect is unmatched at providing a lightweight, uniform, and durable alternative to traditional targets” remarked McKee.
