Calibration Standards for Diffuse Reflection
- Reflectance from 2 % to 98 % at 555 nm
- ODM98 or ODMP plates from 2"x2" / 50.8mmx50.8mm to 10"x10" 254mmx254mm square
- Housing with lid
- 8°/D calibration from 250 nm to 2400 nm with calibration certificate
Large-area reflection standards are used to align and verify laser rangefinders and optical distance sensors. White standards with the highest possible reflectance are used for the 100 % adjustment of the measuring devices, linearity is determined using greyscale standards of different reflectivities.
BN-Rxx-SQ reflection standards
are made of white ODM98 and grey to black pigmented ODMP. ODM98 offers the highest possible reflectance in the wavelength range from 250 nm to 2500 nm and is therefore commonly used as a 100% reference for the instruments and sensors. As a translucent material, it also offers a near perfect Lambertian reflection behavior. Reflective standards are offered in dimensions from 2" x 2" / 50.8 mm x 50.8 mm to 10" x 10" / 254 mm x 254 mm (or 12" x 12" / 304,8 mm x 304,8 mm) in a metal case with protective cap. The BN-Rxx-SQ reflection standards are available with reflectivities of 98%, 70%, 50%, 20%, and 2%.
Each standard of reflection is supplied with an individually prepared calibration certificate for the wavelength range from 250 nm to 2450 nm. The calibration is carried out by the Calibration Laboratory for Optical Radiation Measurements at Gigahertz-Optik GmbH. The calibration is traceable to the Physikalisch-Technische Bundesanstalt (PTB).
Alternatively, the reflection standards are also offered without calibration for use as working standards . In this case, the user performs the calibration on his own using a calibrated reflection standard.
