Permaflect® Diffuse Reflectance Targets

Near Lambertian; 350-1000 nm; Grey Scale Level 5-94%; Uniformity ±1%, ±1.5%, ±2%; Target Size 0.5x0.5-1.2x2.4 m

Labsphere’s Permaflect® large-area, grey and white, reference diffuse reflectance targets are ideal for accurately assessing short-range and long-range sensitivity over the dynamic range of LiDAR systems.

For imaging applications your grey target solution must work for a wide variety of lighting environments and still maintain its appearance. Most importantly it has to have uniform spectral response. It also must be thermally and physically durable, UV light stable, thermally color stable, no gloss, no polarization and no fluorescence.

If your grey target solutions do not meet these requirements, you need Permaflect diffuse reflectance targets. Permaflect targets are available for individual purchase in three sizes: 0.5 x 0.5, 1.0 x 1.0, 1.5 x 1.5 or 1.2 x 2.4 m, unframed and with or without mounting. Available reflectance factors are 5%, 10%, 18%, 50%, 80% and 94%.

Permaflect diffuse reflectance targets are also available in Labsphere's LiDAR Test Target Kits, including three reflectance levels; 10%, 50% and 80%, a robust case that holds all three Permaflect targets for storage and transport, and spectral reflectance and uniformity test reports. The kits come in a choice of three target sizes; 0.5 x 0.5, 1.0 x 1.0 and 1.5 x 1.5 m.
