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.

SMA 光纤适配器位于北极

球体都带有北极 SMA 光纤适配器作为标准功能，允许少量光拾取以用于波长测量或任何进一步分析，不影响整个系统校准。积分球探头都在已安装转接器情况下进行校准。

Post-Mountable for Accurate Measurements

To ensure accurate measurements, it is recommended to mount these integrating spheres securely. One way to do so is by mounting them on an optical post.

高级 –CAL2 型号

带“-CAL2”后缀的型号是有内置热电偶和 OD1 衰减器的探头。当连接到 1830-R、1918-R、1936-R 或 2936-R 型号功率计时，这些探头将自动识别衰减器开/关位置和探头温度。

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 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 current input value. Newport provides 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 application is critical.
