Optical Bench Set & Optical Ray diagram Board-

OOptical Bench Set & Optical Ray diagram Board-4ptical Bench Set & Optical Ray diagram Board-4 Features: Optical bench set Using this optical bench set,you can demonstrate most optical phenomenaand measure the focal length of a convex lens. Conmbine with optical ray diagram board,you can find the relevant optical ray diagrams of image formation presented on the optical bench set. Following experiments can be performed on this optical bench set: 1.Image formation by a convex lens and measure the focal length of a convex lens 2.Dispersion 3.Imagine formation by apinhole 4.The model of Kepler telescope 5.The model of Galilean telescope 6.The model of microscope 7.Double slits interference with different slit width 8.Diffraction formed by single slit with different slit width,diffraction gratings,apertures with different shape and size.a string,an edge and a small circular screen (poisson bright spot) 9.Shadow to simulate the formation of eclipse and lunar eclipse 10.Image formation by a concave mirror and a convex mirror 11.Polarisation produced by a polarizer and detected by an analyser Optical Ray Diagram Board By using laser beams produced by splitter of laser source,various optical ray diagrams presented on this white board show how each optical modular kit works and the image formation by different modular kits.The ray diagram of image formation in some optical instruments such as microsscope and telescope also can be shown on the board.The incident angle,reflected angle and refracted angle can be measured by the scale on the board thus the reflection law and snell's law can be verified and refractive index can be found. Following optical ray diagrams could be shown on this board: 1.Reflection from a plan mirror 2.Reflection from a concave mirror 3.Reflection from a convex mirror 4.Refraction by a prism 5.Refraction by a concave lens 6.Refraction by a convex lens 7.Refraction though a brick and a semi-cylindrical lens 8.Total internal refraction Table of the Accessories Accessories of guide-way experiment Name of AccessoriesQuantityAccessories of white board experimentName of AccessoriesQuantityPlane convex lens F=120mm 1Plane convex column lens F=120mm 1Long focus biconvex lens F=80mm 1Long focus biconvex column lens F=80mm 1Short focus biconvex lens F=45mm 1Short focus biconvex column lens F=45mm 1Plane concave lens F=-120mm 1Plane concave column lens F=-120mm 1Long-focus biconcave lens F=-80mm 1Long-focus biconcave column lens F=-45mm 1Short focus biconcave lens F=-45mm 1Concave/convex column lens F=50mm 1Convex F=50mm 1Isosceles prism base 36mm×12mm, 45° 1Concave F=50mm 1Isosceles rightangle prism 38mm×38mm×12 mm 1Reflecting mirror 100mm×70 mm 2Plane diffuse reflector 50mm×16 mm 2Semi-reflecting mirror 100mm×70 mm 1Water tank, semicircle R40mm×40mm 1Polarizer 1Semi-cylindrical lens R20mm×12mm 1Analyzer 1Trapezoidal brick 4mm×12mm, 45°, 60° 1Take-up screen 100mm×70 mm 1Rectangular brick 47mm×26mm×12mm 1Diffuse transmission screen 100mm×70 mm 1Splitter of laser source 1Pinhole board 1 Letter board 1Empty lens barrel 1Physical optics tester 1Diffraction plate 3Earth analogue board 1Moon analogue board 1
