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. A perfect cosine response provides accurate absolute intensity when multiple lights are measured at same time.
Applications:
- LED Measurement
- Solar analysis
- Laser Characterization
- Display Measurement
Integrating 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.
Applications:
- Light source characterization of spectral intensity distribution
- color temperature
- xy chromaticity
- dominant wavelength for LED, laser, solar, industrial lighting, and any type of light emission.
