特征:
在宽波长范围上的恒定响应
热电堆探头对入射激光束的响应特点由其吸收决定。我们在传感器中使用了两种不同类型的涂层。大多数型号中使用了 BB 型,在整个响应波长范围内具有良好的恒定吸收。919P-050-18HP 模式中使用了 PF 型,专为高能量密度脉冲设计。
针对损伤阈值与脉冲宽度进行了广泛测试919P 系列热电堆探头通过多种激光器对损伤阈值进行了广泛测试。您可以信任我们的规格,安心使用。
Thermopile Sensor Physics
Thermopile optical power sensors are based on thermocouples. A thermocouple consists of two dissimilar metals connected in series. To detect radiation, one metal junction is typically blackened to absorb the radiation. The temperature rise of this junction with respect to another non-irradiated junction generates a voltage. This effect is the basis of all thermocouple temperature sensors. The thermocouple materials used in thermopiles are usually bismuth and antimony, which have a relatively high thermoelectric coefficient. An individual thermocouple typically produces a low output voltage, which results in a low detectivity and limits its use as a sensing device. So, one way to increase the output voltage is to connect many thermocouple junctions in series. All the “hot” junctions are placed close together to collect the radiation. The typical operation of a thermopile is shown above. The thermopile disc consists of a circular array of thermocouples. The optical radiation is absorbed by the disc generating the output voltage. The heat on the disc spreads radially across the thermopile on the reverse side of the disc where it is transferred to a heat sink. These devices are quite sensitive in the IR due to their broadband absorption. Due to the heating and coo领 processes, the response time of a thermopile is quite slow, typically on the order of seconds. Due to this time constraint, thermopiles are used exclusively for measuring the power of CW or quasi-CW radiation sources. Please see our Thermopile Sensor Physics technical note for additional information.
大功率测量的理想选择
Newport 新型的 919P 热电堆探头系列提供了一系列探测器,以满足连续或脉冲激光器的功率测量需求。他们提供了宽带、频域平直的响应,最大测量功率范围高达 5000 W。
NIST 可追溯性
每个 919P 热电堆探头包括一个 DB15 连接器和内部 EEPROM,用于存储工厂校准数据。大多数探头都在 532 nm、1.064 µm 和 10.64 µm 这三种不同波长下校准。建议每年都对热电堆探头进行校准,以确保 NIST 的可追溯性。

Also note that both the series are incompatible with certain optical power meter models. The following table provides the recommended replacement 919P models for each 818P series model. Even though the recommended models have the closest specifications as the obsoleting ones, however, not identical. The user must carefully compare each specification.

Fiber adapters not mountable
The 919P-SMA and 919P-FC fiber adapter can be used with most of the detector models. Remove the snout for Models 919P-003-10 and 919P-010-16 and directly mount the fiber adapters on the thread. In order to accommodate various aperture sizes, we provide adapter rings as well as the fiber adapters. Refer to the table for the corresponding adapter ring for each detector model. Note that certain models do not accept a fiber adapter.
