OT-4040 Portable Laser Alignment System

OT-4040Features

 The On-Trak Photonics OT-4040 Alignment Laser System is a powerful way to perform accurate alignment measurements. It enables measurement of X-Y deviation in real-time at any point on a visible laser reference line - a line extending up to 100 metres long. A "transparent" measurement target can be inserted into any standard NAS tooling sphere along the reference line, and a reading taken with the attached central processing unit. The OT-4040 Alignment Laser System is widely used by aircraft manufacturers, shipbuilders, and the automotive industry.

 A typical system consists of a single Model OT-4040 LL Alignment Laser, OT-4040 TTS4 Transparent Target, OT-4040 TS4 Reference Target, and two OT-4040 Central Processing Units (one CPU for each target). Numerous options are also available.

 The OT-4040 provides a conservatively specified 0.025 mm resolution at distances up to 100 metres. A third generation fibre-coupled laser diode delivery system ensures exceptional beam coherence over long distances - even in demanding outdoor environments.

OT-4040 Laser alignment system

 A stationary laser, aimed at a reference target up to 100 metres away, creates a "line in space" that serves as a measurement reference. One or more transparent targets are placed directly in the beam path. As the laser light passes through each transparent target, the target determines the X-Y deviation of the laser beam with respect to the centre of the tooling sphere. This positioning information is output, in real-time, to a CPU for control, display and analysis. (An optional Remote Data Terminal or computer can be used for data collection or remote operation.)

 Two points in space define a line. The laser is positioned so that the beam is centered on targets 1 and 3. Target 2 can be moved nywhere along the beam path to read X,Y deviation. The side view shows deviation in the vertical (Y) direction; the top view shows deviation in the horizontal (X) direction.

 Internal Fibre-Coupled Laser Diode

• No-compromise performance up to 100 metres.

• Beam centration of 0.05 mm.

• Pulsed at 10 Hz - allows target to be totally unaffected by ambient light.

 Power. An internal rechargeable NiMH battery pack provides 24 hours of continuous use. You can also power the laser using the standard AC wall charger (which simultaneously recharges the batteries).

 Low Power Indicator. Illuminates when the battery pack is low and recharging is necessary.

 Tapered NAS Mount. A chrome-plated stainless steel NAS Mount, slightly tapered near the front of the laser, ensures instant integration into any standard NAS tooling sphere mount.

 2.5 cm Diameter Sensor Area. A large active area makes it easy to place the target into the reference beam path.

 Intelligent Sensor Design. When mounted in a standard NAS tooling sphere, the target's internal PSD is perfectly centered within the sphere to ensure repeatability and insensitivity to errors in angular measurement.

 Positive Magnetic Mounting. Integral magnets firmly lock the target into any standard NAS tooling sphere.

 Leveling Bubble. An integral 30-minute level bubble enables convenient, ultra-precise target positioning.

 Laser indicator. A red LED illuminates continuously while laser light strikes the target.

CPUCentral Processing Unit OT-4040 CPU

 Display. Dual four-digit red LED displays make it easy to read X and Y position - even from several feet away. What's more, seven levels of display brightness helps conserve battery life.

 Pulse Averaging. Average any number of pulses, from 1 to 100.

 Zero Offset Adjust. Instantly set the zero at any point on the detector other than the mechanical/electrical zero.

 Power. The internal rechargeable NiMH battery pack provides 10 to 12 hours of continuous use, depending on user-selected LED brightness. You can also power the system with the standard AC wall charger (which simultaneously recharges the batteries). A yellow LED flashes continuously when the batteries are low.

 Sleep Mode. This battery-saving feature automatically shuts off the CPU after ten minutes of inactivity (ie., laser pulse, key entry or serial port activity). All current settings are saved.

 Laser Indicator A red LED illuminates continuously while the laser strikes the detector.

 Serial Communications. An RS-232 serial communications port makes remote operation easy. Connect your computer or optional OT-4040 RDT Remote Data Terminal to collect data, address targets or perform calibration tasks.
