Optical axis adjusting assembly convenient for adjusting optical path

Abstract

The invention discloses an optical axis adjusting assembly convenient for adjusting an optical path. The optical axis adjusting assembly comprises an optical wedge mounting base, two worm wheel pressing rings, two worm wheels, two wedge mirror worm wheel space rings, a worm wheel pressing plate, two worms, a worm pressing plate and a dustproof mirror. The two wedge mirrors are respectively fixed in the central holes of the two turbines; vent holes are formed between the two wedge mirrors and the two turbines; the two turbines are coaxially arranged in the optical wedge mounting base; a worm gear space ring is arranged between the two turbines; the worm wheel pressing rings are respectively arranged on the other sides of the two worm wheels and the second turbine; the worm pressing plate isfixed on the optical wedge mounting base; the two worms and the second turbines are respectively meshed with the two turbines; worm washers sleeve the two ends of the two worms; the dustproof mirroris fixed at one end of the optical wedge mounting base; the worm pressing plate is fixed at the other end of the optical wedge mounting base and provides pre-tightening force; and the excircle of theworm pressing plate and the optical wedge mounting base are sealed. The optical axis inside the instrument can be adjusted from the outside of the instrument, and the requirements for air tightness and impact vibration resistance of the optical path are met.

Description

technical field [0001] The invention belongs to the field of optical path adjustment, in particular to an optical axis adjustment component which is convenient for adjusting the optical path. Background technique [0002] Micro-adjustment of the optical axis in optical instruments is necessary, either with mirrors or wedge mirrors. The optical wedges used in pairs are often used because of their advantages such as convenient adjustment, high precision, and small space occupation. Such as mirror type, the adjustment accuracy is not high, and the optical axis will change over time, the anti-vibration ability is not strong, and it needs to be installed in the optical path, so the adjustment is inconvenient. [0003] Since the optical axis is generally inside the instrument, when using the paired optical wedges directly, the instrument needs to be opened to adjust the optical axis, which is inconvenient to use. In addition, the conventional wedge mirror is adjusted by manually...

Problems solved by technology

For example, the mirror type, the adjustment accuracy is not high, and the optical axis will change over time, the anti-vibration ability is not strong, and it needs to be installed in the optical path, so the adjustment is inconvenient

[0003] Since the optical axis is generally inside the instrument, it is inconvenient to use the paired optical wedges directly after opening the instrument and then adjusting the optical axis.

In addition, the conventional wedge mirror is adjusted by manually adjusting the wedge mirror. When adjusting the optical path, it is necessary to open the product and turn the wedge mirror directly, which makes it inconvenient to use, and the optical path cannot be sealed, which is easy to bring dust to the surface of the optical parts. In addition, when the energy density is high, the dust is still Can cause damage to optical parts

For large systems, sometimes opening the product will cause the optical path of the entire system to be readjusted
