Product Description Product Descriptionlaser optical demonstration teaching equipmentProduct IntroductionThe principle of the laser optical demonstrator is very simple. The horizontal laser beam emitted from the helium-neon laser is reflected by a plane mirror and then turned 90° vertically upward, and then expanded by a beam expander to become a fan-shaped beam. The fan-shaped beam is split by the dielectric film. After reflection by the dielectric film beam splitter in the beam splitter (abbreviation: beam splitter), also known as the horizontal direction, the fan beam intersects the demonstration screen vertically, so that the beam track is displayed on the demonstration screen. After placing various optical parts on the optical path, various optical experiments can be done.Product SpecificationProduct nameLaser optical demonstration teaching equipmentStructureThe product consists of laser, beam expander, beam splitter, demonstration screen, dial, moving ruler and optical accessoriesMaterialMetal & plasticSize420x140x400mmProduct feature and applicationEasy to useDetailed InstructionsRich experimental contentExperimental projectThe law of straight line propagation of lightThe law of independent propagation of lightlaw of reflection of lightlens beam expanderCylinder lens beam expanderbeam splittergrating spectroscopyDirectional reflection of light on two mediaA plane mirror forms a real image of the converging raysThe plane mirror creates a virtual image of the divergent light.Measurement of the relationship between the rotation angle of the plane mirror and the rotation angle of the reflected light.Determination of Imaging Characteristics of Double Plane Mirrorsdiffuse reflection of light.The phenomenon of refraction of light, the law of refraction and the determination of the reversibility of lightGrazing, Total Reflection and Determination of Critical Angle of LightApplication of the phenomenon of total reflection of lightDemonstration of the periscope principleDetermination of the minimum deflection angle of the prism and its material refractive index n.Determination of parallel displacement when light passes through a parallel plateOptical fiber principleDetermination of Convergence, Focus, and Focal Length of Concave MirrorsAfter reflecting through the center of the concave mirror Cde, the light returns to the original pathThe image formed when the distance from the object to the concave mirror is greater than twice the focal lengthThe image formed when the distance from the object to the concave mirror is greater than one focal length and less than twice the focal lengthThe object is located in the focal plane of the concave mirror, and its image is at infinityThe image formed when the object is within the focal point of a concave mirrorDivergence of Convex Mirror and Determination of Virtual FocusThe light passing through the spherical center of the convex mirror returns the same wayConvex mirror imagingThe direction of the light rays passing through the lens node does not changeDemonstration of the Object Focus of a Positive LensConvergence of positive lens, image square focal point F', focal plane, determination of focal length fcamera imaging principleThe imaging principle of the relay systemThe imaging principle of projection projection systemPrinciple of parallel light sourceMagnifying glass imaging principleImaging characteristics of virtual objects located within the image-side focus F' of the positive lensImaging characteristics when the virtual object is located on the focal plane of the image square of the positive lensImaging characteristics of a virtual object at twice the focal length of the positive lensImaging characteristics when the virtual object is located beyond the focal length of the positive lens double image squareImaging characteristics of virtual objects at infinity in the image side of the lensDivergence of negative lens, virtual focus F', virtual focal plane and back focal length 1 F'The real object is transformed into a virtual image through a prismKepler telescope imaging principleKepler's image of an off-axis object at infinityGalileo telescope imaging principleThe image of an off-axis object point at infinity on the Galilean telescopePrinciples of Microscope ImagingMyopia Correction PrincipleThe principle of farsightedness correctionYoung's double slit interferencewedge-point interferencesingle slit diffractiondouble slit diffractionthree-slit diffractionFour slit diffractiongrating diffractionAperture DiffractionSquare Aperture DiffractionRectangular Aperture Diffractiontriangular aperture diffractionPolarizerNewton's ringsMaintenance and precautions1.The instrument must use 220V, 50HZ AC power supply.2. Do not touch the mirror surface of the beam splitter and the coating surface of other parts with your hands, so as not to damage the coating. Dust contamination should also be avoided.3. Pay attention to protect the paint of Yan Shiping and dial, and do not scratch or peel off.4. After the instrument is used, all optical parts and components should be cleaned with alcohol-ether mixture (the coating surface should be wiped as little as possible, preferably not), and placed in a dry place, preferably in a drying cylinder.5. All diffraction sheets should be placed in a drying cylinder.6. After the instrument is used, press the shield on the beam expander to cover the circular hole to prevent dust from falling on the plane mirror.7. If the laser tube is replaced, the upper cover of the instrument base should be opened first, and the laser tube holder should be loosened. The laser tube should not be clamped too tightly. To repair the laser circuit, open the lower cover of Detailed Photos Company ProfilePackaging & ShippingFAQ
