ApplicationThe optical composite image level is widely used in measuring the gradients of flat surface and cylindrical surface to horizontal direction; The plane ness and straightness of slideway or base of machine tool or optical mechanical instrument as well as the correctness of installing position of equipment.2. Technical data(1) each graduation value: ...0.01mm/m(2) max measuring range: ...0~10mm/m(3) allowance: ..1mm/within one meter... 0.01mm/mWithin full measuring range...0.02mm/m(4) plane deviation on working surface...0.0003mm/m(5) each graduation value of the spirit level...0.1mm/m(6) working surface (LW): ...165 48mm(7) net weight of the instrument: ...2kgs.3. Structure of the instrument:The composite image level mainly consists of the following parts such as micro adjusting screw, nut, graduated disc, spirit level, prism, magnifying glass, lever as well as base with plain and v working surface.4. Working principle:The composite image level uses prism to get the air bubble images in the spirit level composite and magnified to enhance reading accuracy and uses lever and micro screw transmitting system to enhance reading sensibility. Therefore if the work piece with a gradient of 0.01mm/m, it can be accurately read in the composite image level(the spirit level in the composite image level mainly plays the role of indicating zero).5. Operating method:Place the composite image level on the working surface of the measuring work piece and the gradient of the measuring workpiece causes uncoincide of the tow air bubble images; Rotate the graduated disc till the tow air bubble images coincide and reading can be got immediately. The actual gradient of the measuring workpiece can b
