ISPseries fiber optic integrating spheres couple to Ocean Optics spectrometers to measure Irradiance (I) the total integrated reflectance of surfaces placed against the sphere’s sample port (R), or reflection with a gloss trap (RG).
ISP-I integrating spheres are well-suited for measurement of cosine corrected irradiance at the surface of the sample port, or total light emitted from a source put into the sample port. The internal baffle prevents direct viewing of the light source by the optical fiber connected to it.
ISP-R spheres have a port for illumination which is baffled, and a port for viewing at 8 degrees from normal. The RG version also has a removable plug that can act as a gloss trap for measuring just diffuse reflection.
