Model UL270 -Upward Looking 270 mm Sphere Accessory
FromOMT Solutions Bv
The UL270, a unique Upward Looking 270 mm Integration Sphere Accessory, enables precise measurements of diffuse and patterned samples' transmittance and reflectance. It's specifically designed for applications requiring accurate diffuse reflection measurements and addresses the common challenges faced by smaller spheres in performing diffuse transmittance measurements. The sphere has a minimum wavelength range from 300 to 2,450 nm, with an angle of incidence at 8 degrees in both transmission and reflection modes. It provides measurement accuracy less than 0.2T% and 0.5R% for specular samples. The accessory accommodates sample sizes up to at least 250 mm x 400 mm, oriented horizontally. The sphere is made of Spectralon and has a diameter of 270 mm with entrance ports of 100 mm or 50 mm, adaptable via inserts. At the sample position, the beam diameter is 20 mm circular. Detection is carried out using a photomultiplier tube (PMT) for UV/Vis and a broadband InGaAs detector with triple-stage Peltier cooling for NIR.Most popular related searches

The Upward Looking 270 mm Integration Sphere Accessory (UL270) is a unique accessory that allows accurate transmittance and reflectance measurement of diffuse and patterned samples.
For many applications including diffuse reflection measurements small sphere accessories are an excellent choice. The increasing demand for accurate diffuse transmittance measurements however poses a challenge for smaller spheres.
This accessory, the UL270, enables light-diffusing materials to be measured more reliably and accurately than ever before.
