There are three main types of biological pesticides: one is the use of bacteria, fungi, viruses and other microorganisms and their secretions to control the proliferation of pests and diseases; second, the specific insecticide can make the development, behavior, habits and reproduction of pests Obstruction and inhibition, reaching artificial synthetic preparations that control pests and even destroy pest populations.
There are four characteristics of biological pesticides: (1) It is non-toxic and non-polluting to humans and animals. (2) Strong selectivity, no killing of natural enemies; (3) no drug resistance. (4) Easy to use and long residual period. The development of bio-pesticide is listed as the third era of inorganic chemical pesticides and organic synthetic pesticides. It is called the third-generation pesticide. With the increasing demand for pollution-free agricultural products, bio-pesticide will be widely used and become a plant protection work. The new direction.

We are manufacturing high transmission and durability domes. BK7 or HK9L Glass domes are often used in meteorology applications. Fused silica domes are commonly used in underwater applications at extreme environments. Other application for our dome include meteorology applications, pyranometers, defence applications and as high pressure view ports in underwater cameras and submersibles.
