(Labsphere: North Sutton, NH) -- Luminescent materials are extremely important components in many applications, including solid state lighting and medical imaging and diagnostic systems. To measure the quantum efficiency of these critical materials, Labsphere, in partnership with Photal Otsuka Electronics has developed the QE-1000. By employing the companies’ HalfMoon integrating hemisphere, the QE-1000 measures both liquid and solid samples with very high accuracy and reproducibility. The system allows excitation across a broad spectrum of 250–700 nm and detection from 240–800 nm. The QE-1000 will debut during Photonics West 2010 at Labsphere’s booth No. 1437.

“The key to the QE-1000 is the HalfMoon sample chamber, which allows both solid and liquid samples to be mounted in the chamber with reduced errors due to the absorption of the sample holder,” explains Takashi Maruyama, president of Otsuka Electronics. “We are very pleased that Labsphere manufactures the hemisphere with Spectralon, which has the highest possible diffuse reflectance, further reducing errors.”
