Cosine Receptors couple to fiber optic cables and collect light with an 180° field of view using demountable diffusers. A perfect cosine response provides accurate absolute intensity when multiple lights are measured at same time. Cosine receptors provide relative and absolute spectral intensity measurements, for emissive color applications, and for evaluation of light sources such as the Sun, Lamps, LEDs and Lasers.

Radiometry AccessoriesIntegrating Spheres
used to measure light emissions including radiant or luminous flux or light reflectance from sample surfaces. An integrating spheres most important property is ability to uniformly scatter or diffuse light. Light rays incident on any point on the inner surface are, by multiple scattering reflections, distributed equally to all other such points and effects of the original direction of such light are minimized.
Irradiance Calibrations can be performed by StellarNet using NIST traceable lamps (IRRAD-CAL) or by the customer using SpectraWiz software. Applications include light source characterization of spectral intensity distribution, color temperature, xy chromaticity, dominant wavelength (and more), for LED, laser, solar, industrial lighting, and any type of light emission.
