SK173 Diode Laser Diffraction with Standard Slides

Diode Laser Diffraction with Standard Slides Diffraction phenomenon of light can be observed when a laser beam passes through a diffraction slit. The intensity pattern can be determined using a pin photo detector with fine movement across the diffraction pattern. Features: Pin hole with silicon photo detector. Class I diode laser with output power 0.4 – 0.8 mV. All individually slides are protected by two glass plates in frame. Saddle can hold rod from 8 to 15mm. Heavy, rigid and stable Triangular Optical bench (made of Al extrusion). Height and level adjustment screws (made of SS) Objectives: Diffraction of light by single, double and multiple slit. Diffraction of light by fine, cross wire & wire mesh. Diffraction of light by transmission grating and by coarse grating. Diffraction of light by circular aperture. (Pinhole). Diffraction of light by grid and by grey filter. Diffraction of light by tapered single slit and by circular opaque spots.
