2results about How to "Improve anti-reflection ability" patented technology

This invention belongs to the field of photovoltaic glass technology, and relates to a double-layer coated ultra-clear patterned glass for photovoltaic modules and its preparation method. The invention includes preparing an ultra-clear patterned glass substrate, which features high light transmittance, excellent photoelectric conversion efficiency, and low spontaneous breakage rate. A magnesium fluoride layer is deposited on one side of the ultra-clear patterned glass substrate; magnesium fluoride is a material with high light transmittance and low reflectivity, used to improve the light transmittance and anti-reflection ability of the ultra-clear patterned glass. A layer of glass microspheres is deposited on the magnesium fluoride layer to obtain the double-layer coated ultra-clear patterned glass. The glass microsphere layer further enhances the optical performance of the double-layer coated ultra-clear patterned glass. In addition, the glass microsphere layer also provides a certain degree of wear resistance and impact resistance, protecting the magnesium fluoride layer and the ultra-clear patterned glass substrate from damage by the external environment.

The present invention discloses a laser device capable of processing highly reflective materials and a reflected light processing method, belonging to the technical field of reflected light processing. The present invention is designed to solve the problem of reflected light burning the front-end optical path components of the laser during cutting or welding. The present invention comprises: an indicator light laser, a reverse mode stripper, a pump source, a beam combiner, a high-reflective grating, a gain optical fiber, a low-reflective grating, a reverse beam combiner, a mode stripper, a reflected light attenuator and an optical fiber output device. The present invention transmits a large amount of core light into the cladding, and strips the cladding light by stripping technology, ultimately achieving the purpose of protecting the optical path.
