Integrating Sphere, 4-Port, 4 in. Diameter, Barium Sulfate. 1.5 in. Port Plug Included
Model: 819C-SF-4
Product Series Overview
819C Spectraflect Collimated Beam Integrating SpheresThe 819C-SF-4 Integrating Sphere is a 4 inch, Spectraflect coated, 4-port integrating sphere. Its damage threshold is 1.7 J/cm2. The port at 90° is used for the user selectable detector. The port at 180° is for the incoming collimated beam. The port at the North Pole location (top) is for fiber optic taping to monitor wavelength. All spheres include a baffle between the 90° and 0° ports, which prevents direct illumination from the light source to the detector port. By adding Newport's 819M Series port adapters and accessories, numerous integrating sphere configurations can be obtained. Shipped with a 1.5 inch port plug
Ideal Integrating Sphere for Collimated Beams
819C Series modular integrating sphere bodies feature four ports located at 0, 90 and 180 degrees, as well as at the north pole. The baffle is located between the 0- and the 90-degree ports. The 0-degree port is plugged with a port plug and the 180-degree port is used as the input. A fourth sphere port adds functionality to an integrating sphere but also diminishes the uniformity of the light distribution inside the sphere. We offer a wide variety of integrating sphere accessories that mount to the port frames, allowing the sphere to be customized for multiple applications.
819C Series Integrating Sphere Applications
The 819C series integrating sphere is ideal for applications that require use of the 180° port. A detector is typically mounted on the 90° port, while the source beam may enter the sphere through either the 0° or 180° port, depending on the application. Common applications include measuring total collimated laser beam power (including the collimated output of an optical fiber), measuring transmitted radiation from an irradiated sample and measuring reflected radiation from an irradiated sample. For more details about these applications, please see our Integrating Sphere Fundamentals and Applications tutorial.
Cost Effective Barium Sulfate Sphere Coating
Our barium sulfate integrating sphere coating has an effective range from 300 nm to 2400 nm, with reflectivity greater than 97% at 600 nm. It is a cost effective and adequate for most radiation measurement applications. The unmatched environmental stability and high-performance of the Spectralon™ based spheres are derived from their rugged monolithic thermoplastic material and are superior to coated integrating spheres. In addition, their high damage threshold surface can be cleaned with distilled water. However, since the coating is water soluble, we recommend the PTFE based spheres for a high humidity environment.
