Abstract
The utility model relates to a wave plate rotation angle adjusting rack. The wave plate rotation angle adjusting rack comprises a base, a square rack is mounted on the base, a fixed wave plate is arranged in the square rack, one side of the square rack is connected with a rotary plate where a wave plate is embedded, a fixing knob for fixing the rotary plate is vertically arranged at the top of the square rack, the base and the square rack are connected through screw-thread fit, and the square rack can rotate around the base in a vertical direction. By means of the wave plate rotation angle adjusting rack, the phenomenon that the adjusting effect is lost and readjustment is required due to accidentally shaking when an extinction effect is achieved can be effectively prevented, time in the adjusting process can be saved by means of the adjusting rack, the work efficiency is improved, and the adjusting rack is accurate, convenient, simple in structure, ingenious in design, convenient to use and excellent in promotional value.
Description
Technical field
The utility model relates to the optical technology research field, is a kind of wave plate anglec of rotation adjustment rack specifically.
Background technology
Wave plate is a kind of optical device that can make generation additional optical path difference between orthogonal two light vibration.Two mutual polarized components by wave plate produce phase deviation, can be used to adjust the polarization state of light beam.Usually made by birefringence wafers such as the quartz with precise thickness, kalzit or micas, its optical axis is parallel with wafer surface.Impinge perpendicularly on wafer with linearly polarized light, its direction of vibration and wafer optical axis press from both sides θ angle (θ is not 0), and the light vibration of incident is resolved into perpendicular to optical axis (ο vibration) and is parallel to two components of optical axis (e vibration), the o light in their corresponding wafers and e light.The linearly polarized light vertical incidence on wave plate, o light and the e light propagated in the same direction, because velocity of propagation is different, when penetrating from wave plate, its phase differential is π/4 o'clock, and this wave plate is called quarter-wave plate; When phase differential is pi/2, this wave plate is called 1/2nd wave plates or Lamb wave sheet.Under study for action, often need delustring, easily because shake because of carelessness, wave plate meeting fine motion produces extinction effect bad, therefore need to fix after adjusting after reaching extinction effect.The utility model is to make a search for this problem.
The utility model content
The purpose of this utility model is to provide a kind of wave plate anglec of rotation adjustment rack, this wave plate anglec of rotation adjustment rack is shaken after can effectively preventing from reaching extinction effect, lose result, need readjust, this adjustment rack can make adjustment process save time, increase work efficiency, accurately convenient, this adjustment rack is simple in structure, designs ingenious, easy to use, have good promotional value.
The technical solution of the utility model is: a kind of wave plate anglec of rotation adjustment rack, comprise a base, it is characterized in that: be provided with square frame on described base, be provided with fixedly wave plate in described square frame, described square frame one side is connected with the rotating disk of an embedded wave plate, described square frame top is perpendicular to be provided with for the fixing fixed knob of rotating disk, and described base and square frame connect by threaded engagement, and square frame can rotate around the base in the vertical direction.
Further, be provided with the angle index of being convenient to adjust on described rotating disk.
Further, be provided with the magnet that is beneficial to fix on described base.
Advantage of the present utility model: the one, this wave plate anglec of rotation adjustment rack can prevent shake because of carelessness after reaching extinction effect effectively, is provided with fixed knob, and the result that mixes up is fixed, be difficult for change, save time, increase work efficiency, accurately convenient; The 2nd, this adjustment rack is simple in structure, designs ingenious; The 3rd, be provided with the magnet that is beneficial to fix on base, can be easily with random being fixed on the iron laboratory table of wave plate anglec of rotation adjustment rack, easy to use, have good promotional value.
