Electrical connection

230V version: The 230V version includes a power cable with a hollow connector and a matching plug-in power supply.

12–25V version: The laser modules are equipped with a flexible connection cable. If you select the 24V version, a small adapter is heat-shrunk into the power cable. The ends are open and fitted with wire end ferrules, allowing them to be connected directly to an existing power supply or a busbar. Reverse-polarity protection is built-in. Please note that the housing is grounded. If, for example, multiple modules are installed simultaneously in a system, electrical connections between the individual modules can lead to operational problems. In this case, the modules must be installed in an isolated manner.

line length

Depending on the application, modules with different beam angles can be selected to produce the desired laser line length. The larger the beam angle, the longer the line. The following angles are available for our OEM modules:

Angle Distance Line length approx.
5° 1 m 8–9 cm
10° 1 m 17 cm
20° 1 m 0.34 m
35° 1 m 0.62 m
45° 1 m 0.85 m
60° 1 m 1.16 m
90° 1 m 2 m
110° 1 m 3 m
120° 1 m 3.4 m
INFORMATION: The line length increases linearly with distance. At a distance of 2 m, the line length is therefore twice as long.

line width

With our 12 mm modules, the line width—also known as the “focus”—can be quickly and easily adjusted to the desired size or distance. The optics are mounted in the front brass ring and can be adjusted very easily and safely using a fine-pitch thread. This allows the line width to be set to the technically feasible optimum for any desired distance. Once the desired line width has been determined, the optics are secured in the threaded section using threadlocker. Upon request, we’ll be happy to set the focus to a specified value for you.

Equipment / Options

As standard, the modules are equipped with a high-quality, aspheric acrylic glass lens that provides excellent beam quality and focusing of the laser beam. Optionally, the module can be fitted with a 3-lens glass collimator. This primarily affects the temperature stability of the focus. The standard acrylic lenses can shift the focus under significant temperature fluctuations, which may result in a change in beam width. As long as the operating temperature at the module’s installation point fluctuates within a range of ±5°C, the acrylic lens is preferable because it offers slightly better focusing at short distances than the glass lens. The glass lens, on the other hand, offers better beam characteristics at long distances (>2 m). However, if significant temperature fluctuations occur, the glass lens should be selected to prevent the focus from shifting.

For a large divergence angle (110°), we offer a glass line lens that produces a Gaussian-like distribution of light. The laser line is brightest at the center and gradually becomes darker toward the ends of the line, whereas standard optics produce a fairly uniform distribution across the entire beam. Of course, this line lens can also be combined with the glass collimator.

Notes

  • Observe the laser class!
  • Further information on laser safety can be found here.

Optional

  • Glass line optic, finer line, bright in the center, tapering toward the ends
  • Glass collimator, greater stability under temperature fluctuations
  • Extension cables for the power supply in virtually any length

The line length increases linearly with distance; at a distance of 2 m, these values double.

Laser diodes react sensitively to voltage spikes and current fluctuations. An unregulated supply or one with peaks can destroy the diode within microseconds – even if the peak occurs only briefly. Stabilized means: constant output voltage under load (no sag during switch-on). Peak-free means: no switching spikes or overshoot on the supply lines. Always use a switching power supply with sufficient smoothing or a dedicated laser diode driver. Avoid unfiltered supplies, cheap plug-in adapters without filtering, and supplies that are shared with other switching loads.
Our 12 mm line laser modules are available with three connection variants:
Stranded wires (standard) – open red/black wires, approx. 100–200 mm length, for direct connection to microcontrollers or driver boards.
Barrel connector – 5.5 / 2.1 mm standard barrel plug, approx. 200 mm cable, for operation with a 230 VAC plug-in power supply.
Flexible cable with ferrules – approx. 100 cm flexible cable for direct connection to a 12–25 VDC machine controller. Reverse-polarity protection is integrated in the DC variant.

On request we also supply M8 / M12 connectors with custom cable lengths. The DC variant is particularly suited for retrofitting existing machines without 230 V wiring.
Acrylic optics (PMMA plastic): low cost, light, dimensionally stable. Optically very good in standard applications, but temperature-sensitive – the refractive index changes with temperature, shifting the focus when variation exceeds ±5 °C. Perfectly adequate for indoor applications with stable conditions. Glass optics: heavier, more expensive, but temperature-stable. The refractive index stays nearly constant across wide temperature swings. Ideal for: outdoor mounting, unheated halls, machines with large temperature swings (welding, sawmills in summer/winter) and applications needing high repeat accuracy over long periods. Glass optics are available as an optional upgrade on our KLM and LLM modules.
On our 12 mm line laser modules the line width – also called „focus“ – can be adjusted directly on the module. The optics sit in the front brass ring and can be turned precisely via a fine thread. Rotate the ring carefully until the desired line width appears sharp at your working distance. After adjustment, secure the optics with a drop of thread-locking varnish in the thread groove to prevent drift. The adjustment also works while the module is installed. On industrial line lasers (e.g. the IL-HP series) the line width is set at the factory to the customer specification. You can find out how to adjust the line here.
The laser class according to EN 60825-1 determines the required safety measures. Class 1: safe even when looking directly into the beam – ideal for open applications without protective measures. Class 2: visible lasers up to 1 mW, relying on the blink reflex – unproblematic in B2B environments. Class 1M / 2M: eye-safe under normal conditions, but not when viewed through magnifiers or binoculars. Class 3R: increased risk on direct viewing – safety goggles recommended. Class 3B: safety goggles mandatory. Line and cross-line lasers benefit from relaxed rules because they are classified as „extended sources“ (see laser safety).
The IP rating (International Protection) indicates which environmental influences the housing is protected against. IP 40: protected against solid objects > 1 mm, no water protection – for dry indoor use and machine integration. IP 44: also protected against splash water from all directions – typical for industrial halls and covered outdoor areas. IP 65: completely dust-tight and protected against water jets from any direction – the right choice for sawmills and circular saws (wood dust, sawdust), washing facilities, splash-water environments and rough industrial use.
The brightness of the laser line depends on many factors. In short:
Line length: The longer the line, the lower the brightness, as the light output is spread over a larger area
Laser color: Green appears significantly brighter than red or blue
Work surface: The darker and more matte the surface, the darker the light appears
Ambient brightness: The brighter the ambient light, the darker the laser line appears. This is due to the human eye, which reduces its sensitivity depending on the ambient brightness. In direct sunlight, it is very difficult to see a laser line because the retina is already saturated.
Laser power: The higher the laser power, the brighter the laser line

Wavelength in detail: The wavelength determines how visible the line is on your surface. Red (650 nm) is the lowest-cost option and sufficient in moderately lit indoor environments. Light red (635 nm) appears noticeably brighter than 650 nm at the same power. Green (520 / 532 nm) is the most universal choice – the human retina is most sensitive in the green spectral range, so green lines appear roughly 5–7× brighter than red at equal power. Blue (450 nm) delivers high contrast on greenish surfaces, where red and green fade into the background.
A line laser projects a line of light onto a surface – unlike a point laser, which only shows a single dot. The line is generated by a cylindrical lens that spreads the round laser beam into a fan. Typical applications include cut-line projection on saws, circular saws and CNC machines, workpiece positioning in manufacturing and machine integration, operator guidance at manual workstations, and reference lines in inspection and measurement setups. Line laser modules are available in different wavelengths (red, green, blue), power classes (1 – 500 mW) and IP ratings (IP 40 for dry indoor use up to IP 65 for sawmills and splash-water environments).
