Irradiance Integrating Sphere

Product Details Measure Total Irradiance or Reflectance with Models Optimized for Emission Sources or Surface Illumination Ideal for UV–NIR Applications in Materials Testing, LEDs, Lasers, and More White Reflectance Standard Provides Stable, Repeatable Reference Measurements Compatible with Ocean Optics Spectrometers and Accessories Ocean Optics integrating spheres provide flexible, accurate solutions for measuring light output or surface reflectance across a wide spectral range. Whether you need 360° field-of-view irradiance collection, uniform surface illumination for reflectance measurements, or a stable reference for calibration, these integrating spheres ensure consistent, reliable results. The White reflectance standard ( #90-586 ) complements the spheres by providing a dependable calibration reference for diffuse reflectance measurements. Ocean Optics Integrating Spheres are well-suited for UV-NIR applications, including material testing, LED analysis, and laser measurements. Selection Guide: FOIS-1 ( #90-588 ): Best for irradiance measurements and light emission sources; features a 360° field of view for collecting light from LEDs, lasers, and other broad light fields. ISP-REF ( #90-587 ): Best for surface reflectance measurements ; provides even surface illumination and integrates a transfer optic and built-in light source for easy measurement of color or reflectivity on opaque or directional samples. WS-1 ( #90-586 ): Use alongside your integrating sphere for reliable white reference measurements when calibrating for diffuse reflectance.
