Integrating Spheres for Divergent Light Sources
Integrating spheres are used when we have divergent light sources. An integrating sphere has its inner surface coated with a surface that highly reflects (typically 99%) in a scattering, nonspecular way. Thus when a divergent beam hits the walls of the integrating sphere, the light is reflected and scattered many times until the light hitting any place on the walls of the sphere has the same intensity.
A detector placed in the sphere thus gets the same intensity as anywhere else and the power the detector detects is thus proportional to the total incident power independent of the beam divergence. (The detector is so arranged that it only sees scattered light and not the incident beam). An ideal integrating sphere has a surface with reflective properties that are Lambertian. This means that light incident on the surface is scattered uniformly in all directions in the 2pi steradians solid angle above the surface. The surface used by Ophir closely approximates a Lambertian surface.
IS6 Integrating Sphere Overview
For applications that need a large Integrating Sphere, Ophir offers the IS6 series. These are 6” Integrating Spheres, available with and without built-in calibrated sensors, in a range of configurations. Get to know the IS6 family in this video.
Measuring Beams Coming Out of A Fiber
When you need to measure a beam coming out of a fiber, there are some parameters that might have a somewhat different meaning than they do when referring to "regular" beam measurements. Missing some of these points could lead to incorrect measurement, and possible equipment damage. This video clarifies some issues you'll need to keep in mind so you can set up -- and perform -- this measurement correctly.
Measuring Power of LEDs: UV, Visible and NIR
Measuring the emitted power of an LED can be tricky. It is different in some important ways from measuring the power of a laser beam. This video shows you how to use the Ophir 3A-IS Integrating Sphere Sensor, along with the Auxiliary LED accessory, to easily make accurate measurements in LED applications.
Calibration Factors - Laser Power/Energy Meter
When a power/energy meter is in "Calibrate" mode, various "Factors" are displayed to the user. This video explains the meaning of each of these factors.
