How to identify liquid fertilizer
Most metallic mirrors are designed to reflect and preserve the quality of the incident radiation. Common substrate materials are glass, fused silica and various metallic materials. Almost any metal can be deposited on a mirror surface. The common metal coating materials are Aluminum, Silver, Gold, Copper etc, We could provide in custom Made sizes and thickness
Concave Spherical Mirrors have
a polished, spherical surface, metallic coating, and curved back. Each
mirror has a positive focal length, and will focus incident light. All
first surface Concave Spherical Mirrors feature a glass substrate.
Metallic
Optical Mirrors are widely used due to a moderate level of reflection
over a very broad spectral range. Protected gold coatings have the
highest reflectance in IR, silver is most efficient in VIS, while
aluminium is economical reflector over entire 300-IR region.
Metal-coated optical mirrors are available for use with light throughout the UV, VIS, and IR spectral regions.

1 Look at the physical state. Good liquid fertilizer products are clear and transparent, clean and free of impurities, and there may be many solid insolubles in poor quality products. 2 called the product quality. The heavier the liquid product of the same volume, the greater the specific gravity. Therefore, the specific gravity is an important indicator to measure the quality of liquid fertilizer products. Good products do not necessarily have a large proportion, but the positive content of small proportion is not sufficient. 3 smell the product. Good products have no smell. There is a strong ammonia smell, the pH is not well mastered, a special fragrance is generally used to cover certain odors, and a pungent odor is generally added to the substance that should not be added. 4 freezing test stability. Good products are placed in the refrigerator for 24 hours and will not crystallize. If the layer is crystallized, there is no choice of raw materials in the production process and no control of the production process.
A layer of dielectric material
protects the coatings of the mirrors in order to make them durable.
Enhanced metallic coatings provide greater reflection across the
operating bandwidth.
