Radish is a perennial herb of the perennial root, born under the roadside sparse forest, or cultivated in the garden. Hi warm and humid climate, cold resistant. The plant height is 0.5~1.5 m, the root is thick and strong, the fleshy cone is conical, and the flowering fruit period is from July to November. After the old ripening or frost, the upper part of the ground is withered, and the underground rhizome will germinate in the coming year. Hi warm and humid environment, not cold-resistant, roots need to cover to survive the winter. The requirements for soil are not strict, but it is better to cultivate sandy loam with deep soil, rich in organic matter and loose fertile soil. It is not suitable for planting in low-lying land. The production techniques of water radish seed are as follows: 1 Selection method of spring seeding mother plant selection method 1.1.
Convex Aspheric elements are widely used to reduce aberrations, aspheric lens is ideal for light collection, projection, illumination, detection, and condensing applications.
VIS coating option provides less than 1.5% reflection from 425 – 675nm. NIR coating option provides less than 1.5% reflection from 600 – 1050nm. Contact our sales department for volume pricing or for help specifying a custom aspheric lens.
