When purchasing a line laser, consider quality of the laser beam, the accuracy and how wide the beam is projected.
Beam Quality
The quality of the laser beam should play an important role in deciding which line laser to purchase. A high quality line laser will provide a crisp beam throughout the line. Whilst a cheap alternative will provide a thicker, more defused laser line. The Leica Lino L2+ incorporates a very high quality laser beam which projects the best laser line of its class. This award winning laser has been designed to project a very crisp line throughout the beams divergence.
Fan of the Beam
The laser line is projected from the laser diode and out through the lens. The angle of the laser line or fan is determined by position of the diodes and quality of the lens. Most line lasers can only project a beam less than 120 degrees with the lens defusing the extreme edges of the beam.
To improve the beams angle, manufactures have adjusted the diodes' position closer to the front of the instrument. This improves the fan of the laser line, but the lens will have no protection against damage and scratches. Leica Geosystems redesigned the Leica Lino L2+ body to allow the diodes to project a wide 180 degree laser line whilst positioning the optics away from the front of the instrument to protect against damage.
Leica are renown for their quality, so it should not be any surprise to see high quality optics integrated into the design of the Leica Lino L2+. This reduces diffusion of the laser line, providing a very crisp laser.
Accuracy of the Laser
The accuracy will determine how level the laser projects the beam. Any item set-out to this laser line will either be level or not depending on the accuracy of the laser. The Leica Lino L2+ provides the highest accuracy of any line laser both in horizontal and vertical plans.
The Leica Power Range Technology provides excellent line visibility even at larger distances. The Leica Lino L2+ automatically compensates for minor alignment errors in the range of +/-4°. During this process the instrument is aligned to mm accuracy. If the automatic self-leveling range is exceeded, the laser automatically signals that the instrument is out of levelling range. Expensive measuring errors are prevented.
An example of use
When setting out tiles for a wall, it will be very noticeable of the tilts are not truly horizontal, or vertical. A line laser will set-out the initial horizontal and vertical line, allowing the contractor to lay the first tile, with subsequent tiles following the laser lines.
For larger areas the contractor will move the instrument further away to project a wider laser line. If the beam of the laser is of a low quality, the laser line on the wall will become defused. Likewise the accuracy of the laser will further compound the problem, projecting a beam that is not truly horizontal.
The Leica Lino L2+ features a very high quality laser beam, projecting a crisp line through the 180 degree fan. This allows the laser to project a wider beam at close range, ideal for small or large projects. The very high accuracy of the beam ensures that the laser is truly horizontal. If the laser is moved back, the combination of beam, optics and accuracy will not hinder the contractor.
