MULTI-CHANNEL RADIATION SAMPLING UNIT Russian patent published in 2021 - IPC G02B26/02 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the field of optical instrumentation and can be used to create optomechanical devices designed to divert part of the radiation from the direction of propagation of the main stream with control of the parameters of the diverted radiation. The multi-channel radiation sampling unit contains dividing optical elements placed at an angle to the optical axis of the main radiation on a support-rotary device with the possibility of changing the angle of incidence and reflecting optical elements with angular adjustments placed at an angle to the optical axis of the radiation reflected from the dividing optical elements. It is equipped with an adjustment platform, on which there is a support-rotary device with dividing optical elements, reflecting optical elements and additionally absorbing optical elements installed with the ability to absorb glare from the faces of dividing and reflecting elements, optical elements are grouped by functionality into optomechanical assemblies, with elements of angular and linear adjustments of both the optomechanical assembly as a whole and each optical element separately, and each optical element is installed in a container frame, for the installation/disassembly of which a lifting device is provided in the optomechanical assembly, and the support-rotary device is made with the possibility of unlimited rotation around the axis and is equipped with a position sensor, while the optomechanical assemblies with optical elements, the support-rotary device, the lifting device, the quotation platform are placed in a sealed housing with laser radiation input/output nodes, cable entry, pipelines and the possibility of personnel access to the internal space.

EFFECT: expansion of operational capabilities by expanding the possibilities for adjusting both, groups of optical elements and each optical element separately, expanding the possibilities for maintenance, condition diagnostics, replacement of optical elements, increasing the protection of optical elements and optomechanical assemblies from the environment, as well as increasing glare protection.
