How to choose a good price and quality Optical Element
When choosing a good price and quality Optical Element, you must first clarify the technical indicators of the "light" used. There are many types of light sources, including lasers, light-emitting diodes, halogen lamps, metal halide lamps and other light sources. There are many wavelengths of laser light sources. , depending on the wavelength, the types of optical elements used are also different. In addition to wavelength, there are several other factors that determine the technical specifications of a good price and quality Optical Element.
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.
Compare the technical indicators of the good price and quality Optical Element and the technical indicators of the laser in the product catalog, and select the optical element that meets the technical requirements such as laser damage threshold and polarization direction.
It is necessary to know exactly what level of accuracy is required for a good price and quality Optical Element. When the specific accuracy grade requirements are not clear, the grades can be divided according to the application.
The lighting system level has no special requirements for accuracy, and its performance should be given priority.
The simple optical system grade not only needs to exert its performance, but also needs to properly consider the problems of accuracy and error.
The interferometer grade needs to have accuracy requirements under the specified usage method.
For specific good price and quality Optical Element product selection, please refer to the selection guide, and also refer to the selection guide and application materials such as "beam expansion method" and "how to use polarizer".
