Zenith Lite™ Ultralight Targets

Zenith Lite™ – Ultra-lightweight Reflectance Targets

  • Nearly ideal lambertian, diffuse reflectance of about 95, 90, 50, 20 and 5 %
  • Constant reflection over the wavelenght range 250 – 2450 nm
  • Tolerance in reflectance value depending on batch in range of +/- 3 %
  • Certified calibration using a PerkinElmer Lambda 950, which is traceable to PTB and NIST
  • 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 ultra-lightweight reflectance targets. The Zenith LiteTM targets are built from a 1 mm or 2 mm Zenith Polymer® diffuser attached to a 10-15mm thick aluminum honeycomb structured plate by special PTFE high performance glue. The laminating technique allows multiple reflectivities on one target with no visible seams (max. width 1040 mm). Targets can be made to any size and combination of white and grey scale reflectivities. The unique backing can be drilled for easy attachment to other mounting devices.
