Extended Range Sensor Introduction

Radiation that drives photosynthesis is called photosynthetically active radiation (PAR) and is typically defined as total radiation across a range of 400 to 700 nm. PAR is almost universally quantified as photosynthetic photon flux density (PPFD) in units of micromoles per square meter per second (µmol m-2s-1,等于每平方米/秒的微量浓因素)从400〜700nm(400至700nm的光子总数)总结。然而,紫外线和远红色光子在400-700nm的范围内的范围内也可以有助于光合作用和影响植物反应(例如,开花)。

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 (e.g., absorption by photosynthetic pigments). In other words, one photon is a single quantum of radiation. Sensors that function like traditional quantum sensors, but measure a wider range of wavelengths can be thought of as an ‘extended range’ quantum sensor.

传统量子传感器的典型应用包括在室外环境中的植物檐篷或温室和生长室中的进入的PPFD测量,并在同一环境中反射或覆盖天篷(传输)PPFD测量。Apogee的新款380-760 nmExtended Photosynthetically Active Radiation (ePAR)和340-1040 nm.扩展光子通量密度(EPFD)sensors are designed for making total photon intensity measurements of wider ranges than traditional PAR sensors that measure 400-700 nm.
