LMT PHOTOMER PAINT

LMT® formula offering wavelength-neutral coating of integrating spheres

LMT® photometer paint is based on a Barium Sulfate formula offering a spectrally neutral reflectance for high performance coatings of integrating spheres.

Several reflection coefficients are available serving different needs:

• PhP 80 for daily use with a reflection of 80% . The 80% formula is extremly robust over lifetime and offers long re-calibration periods.
• PHP 90 having a reflection coefficient of 90% generates an ideal illuminance distribution across the surface of the sphere. It is especially useful for measuring light sources having non-uniform light distributions.
• PhP 92 with a reflection of 92% offers a high performance sphere factor of ≈ 12 and is most often used in combination with spectroradiometers.

LMT® photometer paint is available for repair or maintenance of integrating sphere coatings. It can be purchased according to the size of the sphere in different quantities from 1 kg up to 16 kg.
