Universal Integrating Spheres
An integrating sphere is a hollow sphere with a highly reflective inner surface. It is a high-efficiency device mainly used to collect light scattered or emitted by a sample inside or outside the sphere, or near a window, or the light emitted by the light source itself. It can be used to make precise measurements of the optical reflection and transmission properties of materials, the radiance, luminance, or chromaticity of light sources, etc. The inner shell of the integrating sphere is made of high-quality PTFE material, suitable for ultraviolet-visible-near infrared spectroscopy, and has good Lambertian characteristics within this spectral range. Each integrating sphere has a wide range of applicability. Photometric integrating spheres can be combined with spectrometers, optical fibers, light sources, and various optical measurement equipment to form a system for various sample measurements. Suitable for measuring various samples, such as sample surface reflectance, sample transmittance, light source radiation, etc.
