Problems solved by technology

Since the half-wave plate can only act on a specific wavelength of light, this optical energy attenuation device can only act on a specific wavelength of light, which limits its application range
At the same time, this kind of light energy attenuation device needs to use expensive optical thin film devices, the manufacturing cost is high, and the threshold value of anti-laser damage is low

Abstract

The invention relates to a continuous and adjustable type optical attenuator, comprising a light source capable of emitting light beams. The continuous and adjustable type optical attenuator is characterized in that a first plate optical element and a second plate optical element are arranged in the forward directions of the light beams; the first plate optical element and the second plate optical element are respectively placed on a first rotary platform and a second rotary platform which are arranged on an operating platform and are associated mutually in a gear-meshing manner; and the rotating angles of the first rotary platform and the second rotary platform are equal, and the rotating directions are reverse. In the continuous and adjustable type optical attenuator, the structure is simple, smart and reasonable, continuous and adjustable light energy attenuation can be realized, the applicable waveband range is wide, the adjustment of light paths is not carried out when an attenuation value of the light energy is changed, manual adjustment is not needed due to adopting computer control, the adjusting accuracy is high and the manufacturing cost is low.

Description

technical field [0001] The invention relates to an optical energy attenuation device, in particular to a continuously adjustable optical attenuator. Background technique [0002] Optical instruments and other equipment are playing more and more roles in the fields of physics, chemistry, and life sciences. Light energy attenuation devices are often used in optical instruments, and their main function is to attenuate the light energy in the optical path by a predetermined amount. , so that the light energy meets the requirements of a specific instrument. [0003] There are two main types of light energy attenuation devices commonly used in existing optical instruments: one is to rely on optical filters, and its working method is to use a specific optical element, which has a certain wavelength or a certain range of wavelengths. With a specific transmittance, when the incident light is incident on the energy attenuating sheet, only a part of the light energy can pass through, ...
