Topcon Corporation originally named Tokyo Optical Company went into business in 1932, manufacturing optical surveying systems (e.g. binoculars, cameras, and lenses) for the Japanese Imperial Military. By the end of the Second World War, Topcon was selling its products commercially and expanding its areas of business producing ophthalmic and medical instruments, manufacturing Japan’s first refractometer, and delving into the global market in fields as diverse as infrastructure development, agriculture, and eye care. In 2001, Topcon Positioning Systems was formed to support the wide selection of products available to assist contractors, operators, surveyors, and civil engineers to accurately survey, excavate, and grade construction sites for any size or difficulty of the job.

What sorts of laser levels and equipment does Topcon offer?
  • Topcon RL-H4C Self-Leveling Rotary Grade Laser This horizontal self-leveling laser is designed for the survey, excavation, drainage works, concrete setting, and set-out on the construction site.

This model can rotate at 600RPM, the rotating laser can slope match with automatic cross-axis self-leveling, and an automatic height-of-instrument alert will help avoid errors. The RL-H4C comes with dual LCD displays, rubber grip handles for relocation, and is powered by D batteries that are rated to last up to 100 hours in this unit. This model comes with a 5/8-inch by 11-inch screw thread on the bottom for mounting on a surveying tripod. This laser is suitable for machine manipulation of construction equipment, installation of interior walls and fittings, concrete footings and foundations, and grade and slope matching.
  • LS-B10 Machine Mount Laser Receiver This laser receiver is compact, featuring a magnetic disc built into its back plate for mounting on smaller construction equipment, such as mini-excavators, backhoes, and skid steer loaders. The LS-B10 laser receiver has grade checking and machine control options, weighs under a pound, has 11 LCD channels with out-of-grade detection, four on-grade zone functions, 270u00b0 detection range at 270 degrees, and red and green LED indicators.
