特征
 | Collimated Beam Input Depending on the beam divergence characteristics of the light source, Newport offers two different types of integrating sphere detectors – Divergent or Collimating. The 819C series are used for a collimated input beam, such as a laser beam. When the collimated beam is measured, the baffle needs to be placed between the first reflection off of the internal wall of the sphere and the detector. The baffle prevents direct radiation from the hot spot from hitting the detector, which allows the spatially integrated beam power measurement. |

 | Integrating Sphere Accessories Newport offers accessories that are compatible with our integrating spheres to build a complete integrating sphere system. Various adapters are available to change port frame diameter, reduce an input port's clear aperture, measure fiber optic power, connect lens tubes and mount sensors. Port plugs to block an unused sphere port are also available. |

| Factors that Affect Maximum Measurable Power |
| The maximum measurable power of photodiode sensors is dependent on several factors such as the wavelength of incoming light, photodiode current output saturation, temperature, use of an attenuator and a power meter's maximum current input value. Newport provides maximum power specifications based on the power meter models, with and without an attenuator, and wavelength-dependent maximum power level. With these factors affecting measurable power in mind, choosing the proper detector for your |
