The beam splitter reflects part of the incident light energy, absorbs a relatively small part, and transmits the rest of the energy. The beam splitter has obvious neutral color characteristics. The beam splitter is made by vacuum evaporation of a multilayer dielectric film. There is no problem that the metal film will absorb. The total penetration and reflection ratio is close to 100. Function: It is made by vacuum evaporation method, and the light can be changed after passing through the filter. The penetration ratio, for example: half penetration and half reflection, with low absorption characteristics.

According to the “Implementation Plan for Intensive Energy-saving Actions in Guangdong Province†promulgated and implemented recently, Guangdong Province has strictly regulated the use of landscape lighting and street lamps, requiring landscape lights to be closed except for major celebrations.
The "Implementation Plan" requires that in the peak hours of daily electricity use, urban landscape lighting, neon lights in entertainment places, etc. should reduce electricity consumption by more than 30%. The specific measures are led by the Guangdong Provincial Construction Department.
The "Implementation Plan" also pointed out that unnecessary night lights should be turned off at administrative agencies and public places at all levels. In addition, under the premise of ensuring the safety of vehicles and pedestrians, street lights should be turned on and off reasonably, and lights should be turned on at intervals to promote the use of renewable energy street lamps such as solar energy and wind energy.

When the laser power that needs to be measured is far greater than the power/energy meter measurement range that can be provided, a beam splitter can be used.
