A mirror is an optical element that uses the law of reflection. Mirrors can be divided into plane mirrors, spherical mirrors and aspheric mirrors according to their shapes; according to the degree of reflection, they can be divided into total reflection mirrors and half mirrors (also known as beam splitters). According to the coating, it can be divided into aluminum-plated mirrors, silver-plated mirrors, and copper-plated mirrors.

Cutout features:
The dropout fuse is mainly used to protect lines and transformers against short circuits and overload. Rated voltage: 12KV~36KV; Rated current: 100A, 200A.
1. Interrupting current capability: interrupt current 12.5KA; maximum 16kA fault current/four times.
2. Long creep age distance
3. Fuse tube is composed of Epoxy fiberglass tube and bone fiber. Moisture resistances, high interruption capability, deform resistance, UV resistance, and aging resistance.
4. Material of Contacts consists of copper and copper alloy, and surface is silvered to reduce the resistance, improve conductivity, and lower temperature rise.
5. The lower pocket and contacts are made of copper alloy casting and heat galvanized to achieve high strength, and high resistance to corrosion, and can withstand thermo and dynamic impulse caused by short-circuit current.
6. The upper and lower contacts have good alignment property. No aliening adjustment needed during installation, and easy for operation.
7. Heat galvanized metal parts, high pollution resistance, and 1000h salt-fog pollution test passed.
8. Advanced design to assure fuse tube being hooked after dropout for safety consideration.
9. Interruption using stepwise structure; can interrupt high and low fault current credibility.
10. Water resistance: pressure-relief cap of upper contact has water resistance and can reduce ionized gas to affect the upper circuit. Button of fuse link can promise inside of tube dry.
11. Manufacturing process has high precision; interchangeability
12. Light weight, small volume, convenient to install
Aluminum-plated mirrors have relatively high reflectivity from ultraviolet to infrared. The optical film is more stable than other metal materials, because the surface of the aluminum film after coating can produce an aluminum oxide film in the atmosphere. Aluminized The reflector uses magnesium fluoride and lithium fluoride as a protective layer in the ultraviolet band, and uses silicon monoxide or aluminum oxide in the visible and infrared bands.
Silver-plated mirrors have high reflectivity in the visible and infrared bands, with small polarization effects, silver is easily affected by sulfides, and has a short service life.
The gold-plated reflector has a higher reflectivity in the infrared band. The lightness and stability of the gold-plated reflector is better than that of the silver-plated reflector, but it cannot be wiped when it is stained.
The use of a high reflectance mirror can double the output power of the laser; and it is reflected by the first reflecting surface, the reflected image is not distorted, and there is no ghosting, and it is the reflection of the front surface. If an ordinary reflector is used as the second reflecting surface, not only the reflectivity is low, the wavelength is not selective, but also the ghost is easy to produce. However, the use of a coated film surface reflector not only has high brightness, but also is accurate and unbiased, the picture quality is clearer, and the color is more lifelike. The front surface mirror is widely used for optical high-fidelity scanning reflection imaging.
