Integrating spheres are ideal for reflectance measurements, especially if the reflectivity of the sample appears different when the angle at which it is illuminated is varied. This occurs for rough surfaces like brushed metal, unpolished optics and organic samples such as seeds and vegetation. Ocean Optics integrating spheres are available in options for viewing sample spot sizes of up to 8 mm.
In addition, we offer integrating spheres for irradiance measurements of LEDs and other sources. We’ve added them here so all our integrating sphere options are in one place.
