Zenith Polymer® Diffusers
Zenith Polymer® – Foil for Diffuse Reflectance and Transmittance
- Nearly ideal lambertian, diffuse transmittance of about 50, 25, 16, 8 und 4 %
- Nearly ideal lambertian, diffuse reflectance of about 95, 90, 50, 20 und 5 %
- Constant reflection over the wavelenght range 250 – 2450 nm
- Tolerance in reflectance value depending on batch in range of +/- 3 %
- Surface reflectivity is constant in range of +/- 1 % R
- Laser damage threshold: 8 J/cm² pulsed laser
Short Description
SphereOptics provides a large spectrum of Zenith Polymer® diffusers. Those diffusers are available in several different sizes, thicknesses (those define the percentage of transmission) and reflection characteristics. It is possible to attach high level gluing foil on a Zenith Polymer diffuser, which allows an easy processing.
Properties
- Non-polar, insulator, hydrophobic
- Chemically inert, exception: reacts with organic Lithium and Sodium compounds
- Usable temperature range: – 5 °C to 250 °C
- Humidity in range 10-90 %
- Zenith Polymer diffusers are made in sizes 20 x 20 cm, 50 x 50 cm (and 100 x 100 cm)
- Customer specific sizes and reflectivities on request
- Calibration on PerkinElmer Lambda 950 possible on request
Applications
- Field calibration of portable spectrometers (Remote Sensing)
- LIDAR
- Contrast measurements for camera applications
- Homogeneous projector walls for inspection and quality check of whole projectors and projector lamps
- Presentation screens
- Environment laser targets
- Environment test targets
- Light source characteristics and patterns
- Reflectance standard for illumination measurements and calibrations
