Introduction to the use of electromagnetic pulse valve

Electromagnetic pulse valve in use, the premise of the environment before the premise is very important, which is related to the electromagnetic pulse valve can not be normal and steady operation. Electromagnetic pulse valve Environmental conditions: 1, the environment of the highest and lowest temperature should be selected within the agreed range, if any special orders for overcommitment proposed. 2 The rated current and power consumption should be selected according to the power capacity. Should pay attention to AC starting higher VA value, capacity should be preferred indirect induction solenoid valve. 3 According to the type of power supply, were selected AC and DC solenoid valve. In general AC power access convenience. 4 Use in aggressive or explosive environments Priority should be given to corrosion resistance based on safety requirements. 5 If the environmental space is limited, please use the multi-function solenoid valve, because it eliminates the need for bypass and three manual valves and easy on-line maintenance.

Silicon Lens

The refractive index of the monocrystalline silicon material is about 3.42, and the reflectivity of the silicon lens after polishing is about 30% in the air environment. Our common silicon lens and silicon window can be coated on the surface (Antireflection Coating), which can reduce the reflectivity to less than 1.5% between 3 to 5 um.

Some silicon elements, especially the silicon protected windows, are exposed to dust, acid, salt and so on in the harsh environment. The conventional multilayer antireflection coating will be damaged and affect the normal work of the equipment. At this time, we need to make DLC coating on the surface of the silicon lens.

Diamond-Like Carbon (DLC) Coated Silicon Windows are engineered for 3 to 5µm, making them ideal for infrared defense applications such as thermal imaging.
Diamond-Like Carbon (DLC) Coated Silicon Windows provide anti-reflection coating on one surface and a specially designed DLC coating on the other surface, making these windows highly durable and ideal for harsh environments.
