Advantage

▷ General industry-single lens; glued lens can directly measure the eccentric angle；

  ▷ High measurement accuracy-cursor line 0.001mm, large scale, wide grid reading, measurement accuracy up to 5 seconds；

  ▷ Wide measuring range-convex and concave lenses other than flat lenses (including aspherical surfaces)；

   ▷ Simple to use-fast and convenient, fixture standard guide hole ￠50mm; fixture production is simple；

   ▷ Many configurations-configured according to customer needs, image calculator and small lens measuring fixture, measurement accuracy up to 2 seconds (additional charge)；

   ▷ Excellent service-provide customers with eccentricity measurement and gluing and centering solutions (additional billing)；

  ▷H Working height-the working height of eccentric gauges in the industry is generally < 110mm ET1610RA-TV Working height can reach 130mm

Instructions for use

   1.Connect the cables to the power supply to turn on the detection light source. Adjust the knob to the desired brightness；

   2.Place the tested lens on the centering fixture；

   3.Rotate the CHART moving cylinder left and right to lift the CHART position up and down until you find a clear cross light；

   4.Rotary displacement platform Maher measuring tool handle, Adjust (+) to coincide with the cross line of the scale of the reticle；

   5.If you need to increase the working distance, you can rotate the Z-axis displacement platform to lift the eyepiece at the same time, rotate the CHART lifting ring left and right, and observe the cross line on the display to the required detection height D value；

   7.Rotate the lens, the bright cross draws a circle with the lens. The greater the lens eccentricity, the larger the circle drawn；

   8.Read the number of grids of the diameter of the circle on the TV. Its radius is the number of grids of eccentricity；

9.Convert the amount of eccentricity to an angle value；

     The eccentricity of the lens is determined by the number of eccentricity grids and the distance D value between the apex of the sphere (aspheric surface) of the tested lens and the objective lens；

     D value determines the angle value represented by each grid, which needs to be obtained by checking the table or calculating.
