LCP-19 Measurement of Diffraction Intensity - Complete Model

Measurement of Diffraction Intensity - Complete Model This experimental system is suitable for general physics experiment teaching at universities and colleges. The key features include stable performance, easy operation and accurate reading. It helps students to understand the basic principles of Fraunhofer diffraction, and measure the intensity distribution of Fraunhofer diffraction. Through this system, students can enhance their hands-on experimental skills and analytical ability Specifications He-Ne laser 1.5 mW@632.8 nm Multi-slit plate 2, 3, 4 and 5 slits Displacement Range of Photocell 80 mm Resolution 0.01 mm Receiving unit Photocell, 20 μW~200 mW Optical rail with base 1 m long Width of adjustable slit 0~2 mm adjustable Parts Included Name Specifications/part number Qty Optical rail 1 meter long and black anodized 1 Carrier 2 Carrier (x-translation) 2 Carrier (x-z translation) 1 Transversal Measurement Stage Travel: 80 mm, Accuracy: 0.01 mm 1 He-Ne laser 1.5 mW@632.8nm 1 Laser holder 1 Lens holder 2 Plate holder 1 White screen 1 Lens f = 6.2, 150 mm 1 each Adjustable slit 0~2 mm adjustable 1 Multi-slit plate 2, 3, 4 and 5 slits 1 Multi-hole plate 1 Transmission grating 20 l/mm, mounted 1 Photocurrent amplifier 1 set Alignment aperture 1
