Longpass filters are designed to have a sharp transition from reflection to transmission, making them ideal for various applications. Available in a variety of cut-on wavelengths, these filters are designed for fluorescence and order sorting applications.
China star optics can supply a full range of filter. They are shortpass, longpass, bandpass, ultraviolet, infrared, heat absorbing, and color temperature conversion filters. We use material by China to Schott, Hoya, and other manufacturers to process them. Metallic films, colored glasses and thin dielectric films filter are all available per your requirements, filters are widely used in medical instrument, finance, metallurgical, photography,cameras, navigation, military, biography instrument, optical instrument andscience field etc.

How to use plant growth regulators
Plant growth regulators are regulators in living organisms. There are four aspects to be aware of when using them. First, attention should be paid to the use of drugs instead of fertilizers, which means that it cannot replace fertilizer and other agricultural measures. Even promoted regulators must be able to perform their functions with adequate fertilizer and water conditions. Second, do not change the concentration. The concentration of plant growth agents on crops is relatively strict. If the concentration is too large, the leaves will become rich and brittle, and the deformed leaves will dry out and even the whole plant will die. If the concentration is too small, the effect will not be achieved. The third is to pay attention to timely use. The use of plant growth regulators should be based on their type, climatic conditions, duration of efficacy and cultivation needs, so as to avoid unnecessary investment. Fourth, don't mix it at will. Mixing several plant growth regulators or mixing them with other pesticides and fertilizers must decide whether it is feasible or not based on the enhancement or resistance between the mixed pesticides. Do not mix them at will.
