Overview:
The line laser presented here belongs to the InLine series and has an output of 20 mW in the colour light red. Within this series, MediaLas presents industrial line lasers in an 18 mm housing with an integrated laser diode driver. The devices are factory-calibrated and ready for immediate use. The wide voltage input and the optional trigger input allow broadband use in numerous industrial applications and environments.
These laser modules are equipped with ACC control, so that a high degree of stability is guaranteed. Additionally, we have installed a so-called “start ramp” in the integrated electronics, which slowly increases the current in the start-up moment. This dramatically reduces risks to the laser diode due to switch-on peaks. You can therefore assume the maximum in reliability with these modules.
InLine modules can be equipped with various line angles. Furthermore, the design also permits customer-specific setting of the focus length or line width. The cylindrical housing can be clamped in a bracket, which additionally dissipates the gentle heat produced and therefore also increases the service life.
Assembly and line length:
The cylindrical housing with a diameter of 18mm can be easily set in the specially designed, adjustable bracket. This clamps the line laser so that the housing is not damaged. At the same time the generated heat, which is very low with these modules, is dissipated via the bracket onto a metallic surface. The line position is simply adjusted by twisting the laser module in the bracket. The stable aluminium bracket can be adjusted through pan-and-tilt, and clamped. A guide pin additionally sits in the mounting foot, for clean concentricity during the adjustment process. The mounting plate facilitates fastening from the front and rear, by means of threaded inserts.
If the laser is mounted vertically over a work surface, the line length is determined by the distance and projection angle. With inclined mounting, the line length can lengthen significantly.
Electrical connection
The laser modules are equipped with a flexible connecting cable. Connecting ends are equipped with wire termination, to connect to any kind of power supply or distributing bus. A reverse voltage protection is mandatory.

LINE LENGTH
Depending on the particular use case, modules with different beam angles can be selected, which generates the length of the laser line. The larger the beam angle, the longer the line will be. For our OEM modules, the following angles are available:

The line length increases linearly as the distance increases. Therefore at 2 m, the line length is also twice as long.
VISIBILITY AND BRIGHTNESS
The brightness of the laser line is determined by many factors. As a principle:
- Line length: The longer the line, the lower the brightness, as the light output is distributed across a larger surface area
- Laser colour: Green is significantly more effective than red or blue
- Operating surface: The darker and more matte the surface, the dimmer the light appears
- Ambient brightness: The brighter the ambient light, the dimmer the laser line appears. This is determined by the human eye, which reduces its sensitivity to suit the level of ambient brightness. In direct sunlight, it is very difficult to even recognise a laser line, as the retina is already saturated.
- Laser output: The higher the output of the laser, the brighter the laser line appears
