Irradiance Integrating Sphere

• 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.
