Integrating Spheres

Integrating spheres are ideal for reflectance measurements of rough surfaces and measure sample spot sizes up to 8 mm. Integrating spheres also are available for irradiance measurements.

Collimating Lenses

Collimating lenses are curved optical lenses that allow users to control the field of view, collection efficiency and spatial resolution of their setup, and to configure illumination and collection angles for sampling.

  • Collimating Lenses allow users to control the field of view, collection efficiency and spatial resolution of their setup, and to configure illumination and collection angles for sampling.

Cosine Correctors

Cosine correctors are optical diffusers that couple to fibers and spectrometers to collect signal from 180° FOV. Correctors measure spectral irradiance of a plane surface in air or other media.

  • Cosine Correctors are optical diffusers that couple to fibers and spectrometers to collect signal from 180° field of view. Diffusing material options are opaline glass, PTFE and Spectralon.
