Compatible with the old Lab sphere integrating spheres

Some of the older sphere models offered in the past is no longer sold due to low demand. Because the integrating sphere production line has been upgraded. Sphere attachments have been operated, and routinely modified fasteners now require metric tooling. The newer version products now require a 1.5 mm allen wrench. But the set screws on the old products accepted a 0.035-inch allen wrench. The new port frame attachments are not compatible with the old Lab sphere integrating spheres, nevertheless, the old integrating sphere port fixtures and attachments will fit the port frames on a new integrating sphere design.

Operating procedures for sphere mounted illuminators are provided in the separate instruction manual entitled Halogen Light Sources. This instruction manual applies to all Lab sphere standard products, especially integrating spheres, that were manufactured before the mid-year 2004. That is to say, the information still applies except where noted if your integrating sphere includes an older product version. If your system includes a customized product that operates differently than our standard products, additional information is provided in the system manual.

Lab sphere general purpose integrating sphere is optical device capable of a wide range of applications. General purpose integrating spheres collect electromagnetic radiation from a source completely external to the optical device, usually for the purpose of optical attenuation or flux measurement. The underlying properties of their design are easy to understand because of the basis of their versatility. Radiation introduced into an integrating sphere undergoes many diffuse reflections and strikes the reflective walls. The resulting integrated radiation level is directly proportional to the initial radiation level and may be measured easily, using a sphere detector. After numerous reflections, the radiation is dispersed very uniformly at the sphere walls.

Our standard product, integrating spheres, are coated or fabricated from one of three diffusely reflective materials: Infringed and Spectral on. Occasionally Infringed-LF or Dialect coatings may be applied to a customized product. The Infringed, Infringed-LF and Dialect reflective surfaces are applied as coatings. Theses spheres are constructed of two separate hemispheres, each interior covered with the corresponding highly reflective coating. Spectral on integrating spheres are surrounded by a sheet metal shroud and constructed of two hemispheres bolted together. Spectral on is a highly thermoplastic, Lambert Ian material that can be machined into a wide variety of shapes.
