The healthy growth of plants and the absorption of nutrients are closely related. The plant nutrient measuring instrument is a professional instrument specially developed for the detection of plant nutrients by Topp Yunnon. The detection of the plant nutrient measuring instrument is dedicated to the plant itself. Here is a point: Many people will feel the detection of soil nutrients when they are inspecting the nutritional status of the plant. Actually, soil nutrients are soil nutrients. In the absence of plant nutrients, they cannot be counted as plant nutrients. This is two The concept must not be confused. So Top Cloud has targeted the development of plant nutrient analyzers and soil nutrient speed meters. Today we have come to popularize the correct use of plant nutrient analyzers: After power-on initialization, the screen will prompt: “The power-on configuration is successful, please directly clamp the blade measurementâ€, the user can clamp the blade to be measured into the sensor on the head of the measurement clamp, press the Ҡkey to measure once per clamp. , The number of measurements and various parameters can be displayed on the screen. For the same or the same type of test sample, the instrument can use multiple measurements to average. After the same or multiple measurements of the same type are completed, press the Ì„ key to end the measurement. Otherwise it will affect the next or next type of sample to be averaged after measurement, but it will not affect the result of continuing a single measurement. If the user does not have an average value for the same type of sample measurement, he or she can ignore the sampling end. In the system measurement, a single measurement can be achieved by pressing the "" key. Whenever a sample measurement is completed, be sure to press the Ì„ key to end the measurement. Otherwise, when the next sample is measured and averaged, the data of the previous sample will also participate in the averaging operation. Causes calculation errors. The plant nutrient measuring instrument is an indispensable instrument for monitoring crop growth in modern agricultural production. Under the monitoring of plant nutrient measuring instrument, we can more scientifically adjust agricultural operations such as fertilization and irrigation to ensure the healthy and scientific growth of plants.
This lens is made of curve shape, not sphere. The aspherical lens has surface, shown in parabolic surface and polynomial expression. Ellipsoid, hyperboloid, fourth curved surface are examples,Aspherical lenses are designed to reduce spherical aberration
aspheres, are available molded, CNC-polished, or MRF-polished, either with or without anti-reflection (AR) coatings. Aspheres are often employed to collimate light exiting a fiber or laser diode. The surface of an asphere is designed to eliminate spherical aberration.
An Aspheric Lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.
Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations, We could provide Plano Convex Aspheric Lens, plano concave aspheric lens, double convex(biconvex)aspheric lens
