Application and type of optical prism
Common materials include glass, plastic and fluorite. Common types of optical prisms are: Dispersing prism, Penta prism, Dove prism, Wedge prism, Right angle prism, etc. Optical prisms can reverse the direction of light through internal reflection, so they are useful in binoculars.
The characteristics and advantages of the three major laser crystals
Nd:YAG crystal is a solid laser material with the best comprehensive performance. It has high gain, low threshold, high efficiency, low loss, good thermal conductivity and thermal shock resistance. It is suitable for a variety of laser working modes (continuous, Pulse, Q-switching, mode locking, frequency doubling, etc.), widely used in industrial, medical, military and scientific research fields.
