详细说明
驱动光合作用的辐射称为光合作用辐射（PAR），并且通常定义为横跨400至700nm的总辐射。PAR通常表示为光合光子助焊剂密度（PPFD）：每秒每平方米微摩尔的光子通量（μmolm-2s-1，等于每平方米的微量浓因素，每秒汇总400至700nm（从400至700nm的光子总数）。虽然Einsteins和微摩尔相等（一个爱因斯坦=一个摩尔光子），但爱因斯坦不是Si单元，因此表达PPFD为μmolm-2s-1is preferred.
Sensors that measure PPFD are often called quantum sensors due to the quantized nature of radiation. A quantum refers to the minimum quantity of radiation (one photon) involved in physical interactions (for example, absorption by photosynthetic pigments). In other words, one photon is a single quantum of radiation.
Typical applications of quantum sensors include incoming PPFD measurement over plant canopies in outdoor environments or in greenhouses and growth chambers, and reflected or under-canopy (transmitted) PPFD measurement in the same environments.
The CS310 quantum sensor consists of a cast acrylic diffuser (filter), photodiode, and signal processing circuitry mounted in an anodized aluminum housing with a cable to connect the sensor to a measurement device. The CS310 quantum sensor is designed for continuous PPFD measurement in indoor or outdoor environments. It outputs an analog signal that is directly proportional to PPFD. The analog signal from the sensor is directly proportional to radiation incident on a planar surface (does not have to be horizontal), where the radiation emanates from all angles of a hemisphere.

Spectral Response
Refer to the mean spectral response graph in the网页的图像部分. The graph shows the mean spectral response measurements of six replicate Apogee SQ100 and CS310 quantum sensors. Spectral response measurements were made at 10 nm increments across a wavelength range of 300 to 800 nm in a monochromator with an attached electric light source. Measured spectral data from each quantum sensor were normalized by the measured spectral response of the monochromator/electric light combination, which was measured with a spectroradiometer.

安装
Accurate measurements require the sensor to be leveled using a 18356 leveling fixture. This leveling fixture incorporates a bubble level and three leveling screws. The 18356 mounts to a crossarm using the CM225 mounting stand or 015ARM. The CS310 should be mounted away from all obstructions and reflective surfaces that might adversely affect the measurement.

The leveling base provides physical stability and helps ensure the sensor is leveled correctly. It is not recommended to use the sensor without the base. The sensor mounts to the base with an included bolt. However, a user-supplied plate with a hole drilled in it could be used instead to accept the sensor’s mounting bolt.

The Clear Sky Calculator (www.clearskycalculator.com）可用于确定量子传感器重新校准的需求。它决定了在世界任何地方的任何时候在水平表面上发生的PPFD。在春季和夏季的夏季和夏季使用时在太阳中午使用时最准确，在多个清晰和未污染的日子内的准确性估计为世界各地的所有气候和地点均为±4％。为获得最佳精度，天空必须完全清晰，因为来自云的反射辐射导致进入的辐射增加到高于清晰天空计算器预测的值。由于云的侧面和边缘的反射，PPFD的测量值可以超过清晰天空计算器预测的值。该反射增加了进入的辐射。高云的影响通常显示为上方透明天空值的尖峰，而不是恒定的偏移大于清晰的天空值。
要确定重新校准需要，请将输入站点条件输入计算器，并比较PPFD测量以计算清晰的天空的PPFD值。如果在太阳中午附近多天的传感器PPFD测量比计算值始终不同（超过6％），则应清洁传感器并重新调整传感器。如果在第二个测试后PPFD测量仍然不同，请联系Campbell Scientific进行RMA以获得重新校准的传感器。
