Overview of IS6-D-UV Integrating Sphere：

User's Manual

The IS6-D-UV is a 6” integrating spheres (5.3” inside) with a Silicon detector for use with divergent (D) beams. The IS6-D-UV comes with a UV detector, is calibrated from 200 to 1100nm and can measure up to 1W.

Influence of Absorber Surface Damage on Measurement Accuracy

If the damage causes a change in absorption, the damage to the absorber surface will affect the reading. One way to check this is to move the beam slightly away from the damaged area and see if the reading changes and how much. When the damage threshold is specified, at this power or energy density value, appearance damage may occur, causing some color changes on the surface. However, the damage threshold is usually defined as the power or energy density that causes changes of more than 1%.

Influence of electromagnetic interference on measurement accuracy

Ophir instruments and sensors are certified to meet CE requirements for electromagnetic radiation sensitivity and emission. At almost all radiation frequencies where the intensity reaches the limit specified by CE, people will not notice any interference. In very few cases of specific frequencies, there may be some obvious interference. It has been specified that the maximum interference that can be seen at any frequency is less than 0.3% of the full rated power.
