Selection of optical components<\/h1><\/h1><\/div>

This article introduces the selection of optical components from the aspects of optical path diagram, laser technical indicators, optical system grade, etc.<\/p>\n<\/div>

Optical Path<\/h3><\/h3><\/div>

When establishing an optical experimental device, or an optical system, the optical path diagram should first be prepared according to the optical principle.
\nThe technical requirements of each optical element in the optical path diagram shall be confirmed one by one and recorded in the optical path diagram.
\nAccording to these technical requirements, it is the best to choose optical components, but there are many optical components with similar performance in the product catalog, which one is better to choose, sometimes it is hesitant.
\nHere, we introduce 2 important factors to consider when choosing optics.<\/p>\n

Laser Specifications<\/h3><\/h3><\/div>

When choosing optical components, the first thing to do is to clarify the technical indicators of the “light” used. There are many types of light sources.
\nThere are lasers, light-emitting diodes, halogen lamps, metal halide lamps and other light sources in this catalog. There are many wavelengths of laser light sources, and the types of optical components used vary depending on the wavelength. In addition to wavelength, there are several other factors that determine the specification of an optical component.<\/p>\n

\"\"<\/p>\n

For the above technical indicators, if there is any unclear place, please check the manufacturer’s name and product model of the laser, and confirm with the manufacturer.
\nCompare the technical indicators of the optical components and the technical indicators of the laser in the product catalog, and select the optical components that meet the technical requirements such as laser damage threshold and polarization direction.<\/p>\n<\/div>

class of optical system<\/h3><\/h3><\/div>

It is important to know exactly what level of accuracy is required for the optics. When the specific accuracy grade requirements are not clear, the grades can be divided according to the application.
\nThe lighting system level has no special requirements for accuracy, and its performance should be given priority.
\nThe simple optical system grade not only needs to exert its performance, but also needs to properly consider the problems of accuracy and error.
\nThe interferometer grade needs to have accuracy requirements under the specified usage method.<\/p>\n\n
