Development of optical quantum recorders
Light quantum recorders are special instruments for recording photosynthetically active radiation. Photosynthetically active radiation is related to the photosynthesis of the crop, which in turn affects crop yields. Therefore, in agriculture or in forestry, we usually need to study photosynthetically active radiation, and light quantum recorders are developed in this context. Photosynthetically active radiation is light intensity, ie, the number of effective photons received per square meter in one second (ie, the number of moles of photons), and one photon of light is equal to the Avogadro's constant photon, and the radiation unit is written W. /m^2 Read as: How many watts per square meter (watts/square meter). Optical quantum recorders are also called optical quantum meters and photosynthetic active radiation recorders in the instrument industry. Whether it is an optical quantum meter or a photosynthetically active radiation recorder, it is actually a concept of measuring a certain band of radiant energy that is absorbed and transformed by a plastid pigment of a green plant and used to synthesize organic substances. Photosynthetically active radiation is the source of energy for plant life activities, organic matter synthesis, and yield formation.
The portion of solar radiation that can be used by green plants for photosynthesis becomes photosynthetically active radiation, abbreviated as PAR. The effective radiation wavelength range is roughly in the range of 300-800 nm. It is the most important source of energy for plants, and it is the basic energy for the formation of biomass. It directly affects the growth, development, yield and product quality of plants. As a result, the development of photoquantometers has become a necessity for development. The production of optical quantum meters has increased the efficiency of photosynthetically active radiation measurements in agricultural and forestry research and production departments, making light quantum measurements very convenient.
Optical quantum recorder is the spectral response of the probe to simulate the effective photosynthetic function, the instrument digital display, small and portable, with good accuracy and stability. It has a small size, easy to carry, touch switches, large-screen dot-matrix LCD display, easy operation, full Chinese menu operation, simple and convenient operation. The host of the optical quantum recorder has a powerful storage function, which can save up to 30,000 data at the same time, and can also look at the previous data on the host computer. The relevant parameters of the optical quantum recorder are as follows: Range: 1-2,700μmol/m2·s (400-700nm); Repeatability: Temperature: 20°C-25°C; Humidity 20%-80%: ±5%; Linearity: Full scale ±1%; resolution is 1μmol/m2·s; spectral response bandwidth is 400-700nm. The quantum ray recorder successfully solved the fast and accurate measurement of light radiation, bringing great convenience to the research of agriculture and forestry.
