Brief introduction: PG15-J laser plane interferometer is a convenient optical precision measuring instrument, which is mainly used for accurate optical flatness measurement. The instrument is equipped with a laser light source (wavelength is 6328A). The interference fringe can be seen, measured and recorded for photographic retention. The pg15-j laser plane interferometer is generally required for shock resistance. The instrument can be used in the optical workshop, laboratory and measurement room. For example, if necessary accessories are purchased, the tiny wedge Angle of the optical plate, the uniformity of refractive index n of the optical material, the flatness of the optical coating surface or the surface of the metal bar gauge, the right Angle error of 90o angles and the mono-angle and integrated error of the Angle cone prism can be measured accurately. Points: PG15-J laser plane interferometer is based on the principle of double beam equal thickness interference. According to the research results of modern optics, light has both wave and particle characteristics. The interference of light is a characteristic of its wave. Main technical parameters: 1. The first standard plane (surface A) without coating. The diameter of work: D1 = Φ 146 mm Less than 0.02 minus m(beats /30). 2. The second standard plane (B surface) without coating. Working diameter: D2 = Φ 140 mm Minus 0.03 minus m(beats /20). 3, the collimation system: aperture F / 2.8, working diameter: D1 = Φ 146 mm Focal length: f = 400 mm. 4. Micrometer eyepiece: focal length f=16.7mm, magnification factor is 15X, field Angle 2w=40o Imaging objective: I, D = 4.5 П, D = 7 Ш, D = 10 F = 16 f = 23 f = 37 5. Dimension of interference chamber: depth 260* width 300*190mm. 6. Light source specification: laser ZN18 (he-ne). 7. External dimensions of the instrument: length * width * height 350*400*720mm. 8. Instrument weight: 100kg.
