Product Details

Product Model: 61-6948-51
Product Brand: SIGMAKOKI CO., LTD.

Features

  • Cylindrical lens with polished side.
  • This product can be ***d to collect laser light thinly, to form a sheet-like beam, or to irradiate a long line in the distance.
  • By making the rod diameter smaller, it can be ***d as a lens with a shorter focal length than a cylindrical lens.
  • Precisely machined and polished, it provides a straight line without distortion or b***ing when projected far away.
  • It can also be placed just before the line sensor to allow more light into the sensor.
  • Use a small lens holder (MLH-10) or a cell foc lens (R) holder (MLH-SF) to fix the rod lens.
  • * End face is not polished.
  • * Allow light to enter from the side.
  • * Large spherical aberration occurs due to the small curvature of the rod lens.
  • Use a cylindrical lens (CLB/CLSQ) for precise optics.
  • * When the laser beam is diverged by the rod lens, the diverged light may enter the worker's eyes dep***ing on the direction.
  • * When using, check the power of the laser and take safety measures such as using protective glasses.
  • * The both ***s of the rod are not chamfered, so be careful not to cut your fingers or hands.
