The LPT1 is the most accurate and longest range 3D laser projector in the world and is protected by United States patent number 6,547,397 and various European patents.  Since its original introduction in 2000 the LPT1 long range 3D  laser projector was the first 3D  laser projector in production to utilize a modulated, pumped, solid state Nd:YAG frequency doubled laser producing a 532 nm green laser beam with internal power feedback and power control to maintain the laser power level at or below 5 mw.  All other laser projector manufacturers at the time of the release of the LPT1 were using a much higher power continuous wave (CW) laser source (above 5mw) with the laser beam modulation and laser projector output power provided by an inefficient acousto-optic modulator (AOM).  As none of the Laser Projection  Technologies Inc. laser projector  designs incorporated the use of an AOM for laser beam modulation or laser projector power control a modulated, pumped, solid state Nd:YAG frequency doubled laser producing a 532 nm green laser beam with internal power feedback and power control has been incorporated into the design of all LPT  laser projectors since the year 2000.  This advanced laser with internal power control has been incorporated into all models of Laser Projection  Technologies Inc. standard 3D laser projectors to meet the requirements of the United States Food and Drug Administration (FDA), Center of Devices and Radiological Health (CDRH) Class 3a and the European International Electrotechnical Commission (IEC) 60825-1 Class 3R laser safety regulations and requirements.  Since the introduction of the LPT1 every Laser Projection  Technologies Inc. 3D laser projector has been designed in a sealed and thermally controlled enclosure.  These  laser projector  enclosures provides Laser Projection  Technologies Inc. customers with unmatched performance and reliability with a rugged, sealed and temperature controlled industrial enclosure.  The LPT1 is also enjoys the largest install base of sealed 3D laser projectors by any manufacturer of similar types of laser projection equipment in the world.  With hundreds of successful customers worldwide this system enjoys the position of 'Best In Class' 3D laser projector in the world.

In April of 2003 Laser Projection  Technologies Inc. introduced the LPT5 medium range 3D laser projector at the JEC show in Paris.  This innovative 3D  laser projector design offered a unique enclosure with the optics and electronics separated by a centrally located active thermal cooling chamber tunnel (advertised as an active thermal cooling matrix).  This cooling chamber tunnel is actively cooled by a series of electric fans that are located at one end of the cooling chamber tunnel to remove the heat generated by the internal power supplies and motor controllers of the laser projector. This cooling system keeps the laser projector at nominal operating temperatures and keeps the heat generated by the electronics from disturbing the optics located within the projector even in harsh or higher temperature shop environments.  This advanced Laser Projection  Technologies Inc. design passes ambient shop air across aluminium fins that are enclosed within the cooling chamber tunnel thus exchanging the heat generated by the electronics within the laser projector directly to the shop air that is exhausted out of the cooling chamber tunnel directly to the shop lowering the internal temperature of the laser projector.  The internal power supplies and other heat generating components are mounted directly to the opposite side of the aluminium extrusion that comprise the fins assembly within the cooling chamber tunnel.  This unique Laser Projection  Technologies Inc. design utilizes no filters of any kind and can be used in extremely harsh shop environments.  Since the introduction of the LPT5 3D laser projector many competitors have tried to imitate this innovative design but the original concept, design and implementation was accomplished by Laser Projection  Technologies Inc. in early 2003.  LPT also exhibited the LPT5 laser projector at the SAMPE show in Long Beach CA in May of this year.  Beware of copycat imitators, since the summer of 2003 Laser Projection  Technologies Inc. has delivered hundreds of LPT5 laser projectors to an extremely large customer base across the world.

The Laser Projection  Technologies Inc. current laser projectors the LPT1, LPT4, LPT12 & LPT100 are all designed with sealed temperature controlled enclosures and contain an embedded computer for system control along with a high level main system computer that runs a Windows operating system for overall 3D  laser projector  system and process functionality.  The LPT8 is contains only an embedded computer and requires an external computer to complete the system.  The LPT12 is the next generation of the patented LPT10 laser projector with feature detection. The LPT12 is smaller faster and 16 times more accurate due to the use of digital galvanometers.  The All Laser Projection  Technologies Inc. 3D  laser projectors are provided to customers with the RayTracer Software Suite with each projector at no additional charge.

With the introduction of the LPT100 (patent pending) Laser Radar Projector Laser Projection  Technologies Inc. has changed the world of three dimensional laser guided assembly and measurement.  By combining the feature detection capabilities of the LPT10 3D laser projector with feature detection (United States patent number 7,306,339) with a extremely  accurate laser radar range detection system this leading edge device is positioned to drive advanced manufacturing and measurement applications well into the 21st century.

Embedded within the LPT100 is a fully functional highly accurate  laser radar  which is capable of scanning 3D objects and returning a high density point cloud that is an accurate representation of that object.  Using its unique intensity based detection system the LPT100 can also detect and measure features of an object with respect to a model to determine the position or location of each feature.  The LPT100  Laser Radar  Projector will also produce single point measurement within the field of view.   Feature detection and measurement can be set up as an automated inspection routine at each step in the manufacturing process.  The operator is guided through the manufacturing process by the means of a glowing laser templates.  Each 3D laser template is a unique 3D wire frame (a type of 3D wire frame hologram) of the items or features to be assembled (Bracket Placement).  Once the items or features are assembled the LPT100 can scan and measure the assembled components and then compare them to a model to determine if they have been assembled correctly.

When used as a  Laser Radar  scanning device the LPT100 can collect 100,000 points per second at an accuracy of +/- 0.005".  Each scan makes up a point cloud that defines the article that is scanned.  There is no other device available anywhere in the world that can achieve a scan at this rate with this level of accuracy.  LPT100  Laser Radar  Projector can be operated by any of the commonly used Metrology Software Programs that are in use today to collect and analyse the point cloud data obtained by the LPT100  Laser Radar  Projector.  Once the scan data is obtained by LPT100  Laser Radar  Projector the point cloud can be surfaced and fit to a design model to obtain a deviation point cloud.  This deviation point cloud can then be fed into the Laser Projection  Technologies Inc. patented RayTracer TOPO Software which can produce perimeter boundary lines that define areas where the as built product deviates from the design master.  The LPT100  Laser Radar  Projector can then project the areas where the that are out of tolerance directly onto the surface of the as built product.
