Zenith Light Diffuse Targets
Zenith Lite Diffuse Targets
Zenith Lite Diffuse Targets are made from Zenith diffuse reflectance material, which provides nearly ideal diffuse lambertian reflectance over the wavelength range from 250 to 2500nm. The Targets are constructed using a 1 mm or 2 mm thick Zenith panel laminated with a special adhesive to a 10 mm thick aluminium honeycomb structured plate that serves as a solid, but lightweight backing. They are the ideal choice for both laboratory and field applications since they are lightweight and can withstand harsh environments for long exposure periods. Due to their design, very flexible mounting solutions are possible.
The laminating technique used with Zenith Lite targets allows for multiple reflectance values in one target with almost no visible seams. Targets can be made to any size and combination of white or gray scale reflectance. The aluminium backing can be drilled to allow for attachment to a variety of mounting devices. Even with a 1 mm or 2 mm Zenith film, the diffuse optical properties are maintained.
All targets can be provided with the National institute of Standards and Technology (NIST) or the Physikalisch Technische Bundesanstalt (PTB) traceable calibration certificates from 250 nm to 2500 nm. For the targets bigger than 200 x 200 mm a smaller reflectance target (witness sample) is provided and the calibration is performed on the reference.
Zenith Full Material Targets
Although the Zenith Lite Targets cover a wide range of applications, in some cases, the purity of the material and volume reflection (bulk scattering) is required. For vacuum applications or use under space conditions, only pure optical PTFE can be used. There is also the option to vacuum bake the raw PTFE material before production. We offer a restricted choice of standard sizes, so for custom, sizes please contact us directly.
