Description

The laser diode beam sources series 5LT-1/5LTM-1 and 5LT-2/5LTM-2 produce semi-telecentric laser lines with a Gaussian intensity distribution along the laser line. They differ in their line length and line width.

5LT-1 vs. 5LT-2
The laser diode beam sources series 5LT-1 produce a semi-telecentric laser line with a line length in the range of 4.8 mm. For most laser diodes the intensity profile is Gaussian in line direction clipped by an aperture at line length 4.8 mm with an edge intensity of typ. <40%. In some cases the line length is slightly smaller. In this case the line length is given on the 13.5%-level and the beam is Gaussian in line direction and truncated at 4.8 mm. The line width is constant along the laser line. Across the laser line the intensity distribution is Gaussian for series 5LT-1 and approx. Gaussian for series 5LTM-1. 

Micro and Macro lasers
The lasers of series 5LT-1 and 5LT-2  are Laser Micro Line Generators designed to produce lines with small line width. They have a small depth of focus (in this case the depth of focus is the Rayleigh range). Laser Macro Line Generators like the corresponding lasers of series 5LTM-1 and 5LTM-2 have common basic optical features but are designed to generate laser lines with an extended depth of focus.

Electronics
The lasers have integrated electronics for control of the laser output power. The output power can be controlled using the modulation input ports (TTL and analog) or manually using the potentiometer. 

RS232 interface
The lasers are equipped with an RS232 interface for laser control and data read-out. It provides e.g. control of ­laser power or allows to switch the laser ON and OFF and it allows to read and store critical data, like the hours of operation or the laser current for maintenance planning purposes.

Adjusting the working distance
For lasers of series 5LT-1 and 5LT-2 the working distance is fixed. A fine-adjustment of the distance between laser and target is recommended for fine-focusing in order to achieve minimal line width.

The laser diode beam sources series 5LT-2 produce a semi-telecentric laser line in the range of 2 mm line length. The line length is given on the 13.5%-level. The intensity profile is Gaussian in line direction. The line width is constant along the laser line. Across the laser line the intensity distribution is Gaussian for series 5LT-2 and approx. Gaussian for series 5LTM-2. 

These high quality lasers can e.g. be used for machine vision applications, laser triangulation or laser light sectioning.
