特征

Exce llent Photodiode Linea rity		Responsivity Variation over Temperature
全不锈钢结构		全不锈钢结构
These photodiodes show excellent linearity over a large dynamic range. This is ideal for use in applications that require high accuracy measurements down to the pW level, especially when combined with a high sensitivity power meter that can accommodate the large dynamic range of the optical signal.		A n atural characteristic of a photodiode is for the its optical response to change as the temperature changes near the bandgap of semiconductor materials. Newport’s 918D series sensors feature a thermocouple near the photodiode, which allows certain Newport meters to read the temperature and automatically adjust the responsivity, ensuring the most accurate measurements.
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 a n attenuator, and wavelength-dependent maximum power level. With these factors affecting measurable power in mind, choosing the proper detector for your application is critical

增强 功能 918D 系列光电二极管探头通过*功能提升性能，旨在使其优于 Newport 经过业内验证的 818 系列校准光电二极管探头。它们具有集成的校准数据存储器、内置 OD1、OD2 或 OD3 衰减片（带有电子衰减片开 /关传感器）以及用于温度漂移补偿的传感电子器件（可使探测器在温度变化时 测 量更为准确）。
	宽动态范围（具有内 置衰减器） 的 OD3 衰减技术将我们探测器的校准光学动态范围扩展了三个数量级。我们的衰减器设计提供高损伤阈值和光谱平坦度。通过与 Newport 正在使用的光电二极管相关联的低 NEP，实现了更宽的动态范围。对于小于 1 mW 的输入功率，我们建议将衰减器置于 OFF 位置（对于 918D-UV-OD3R 在 200 - 400 nm 之间则为 0.1 mW），使信噪比达到。该衰减器的通光孔径为 10.3mm。
的校准不确定性 918D 系列包括一个采用 NIST 可追溯标准，利用 Newport 光学探头校准设施维护的高精度设备完成的全光谱响应校准。严格的校准设备和过程控制可实现业内的校准不确定性。每个探头都附有校准数据，这些数据以电子形式存储在探测器的 EEPROM 中。每个探头都附有校准证书以及衰减器模式和无衰减器模式下的实际校准曲线和数据。为了保持精度、保证性能，Newport 建议每年对光电二极管探头进行校准。

	Internal Temperature Sensor The internal temperature sensor on the detector head is used to compensate the responsivity drift caused by the temperature change in the photodiode. The responsivity change is most sensitive around the bandgap, or towards the longer wavelength limit. The power meter calculates the temperature and automatically updates the responsivity value so that the measurements remain accurate. This feature is enabled with the power meter models 1936-R, 2936-R, 1919-R, and 841-PE-USB.

Adapters for Fiber-Optic Applications
These photodiode sensors can be converted to measure optical power from connectorized or bare optical fibers. Newport offers a comprehensive set of screw-in fiber-optic adapters to match a variety of connector types. Our bare fiber holder and adapter mountare designed together to hold 250-µm bare fibers without damaging the fiber.
