LASER PROJECTION FOR ALL INDUSTRIES

Optimize your workflow with Optolas lasers projection for alignment and positioning tasks.

Optolas OL-LA Series

OL-LA Series

Optolas OL-LA is a series of mini laser diode modules ideal for many applications where a very small size laser is required (22mm in length and 11mm in diameter).

Optolas OL-LB Series

OL-LB Series

Optolas OL-LB is a series of very small size laser modules (60mm in length and 11mm in diameter) ideal for many applications, including pre-hole targeting, alignment, robot control, positioning and edge detection.

Optolas OL-LC Series

OL-LC Series

OL-LC is a series of laser modules widely used in industry. Compared to the LA and LB models, thanks to its casing, it can be equipped with higher power diodes.

Optolas OL-LD Series

OL-LD Series

The Optolas OL-LD series is an M18 threaded laser diode module capable of projecting dots, lines or special projections such as crosses or grids, making this module the ideal solution for many applications in the industrial and scientific sectors.

Optolas OL-LE Series

OL-LE Series

The OL-LE Series is a laser module with a 20mm diameter aluminium housing. This laser can be equipped with different diffractive optics to project sharp dot, line, multiline, cross, grids or special patterns.

OL-LF Series

OL-LF Series

The OL-LF series comprises 20mm diameter laser modules in an anodized aluminum body. These lasers are reverse polarity protected, transient protected and highly resistant to vibration.

OL-LG Series

OL-LG Series

The OL-LG series consists of laser modules that complement the features of the OL-LE and OL-LF series by adding the possibility of manually changing the laser focus.

Optolas OL-LH Series

OL-LH Series

The OL-LH series is made up of laser modules which integrate the characteristics of the OL-LF series with the difference that the projection takes place at 90° with respect to the longitudinal axis of the laser.

Optolas OL-LI Series

OL-LI Series

OL-LI series is mainly used in stone and wood cutting machines. The internal electronics of the laser allow it to be powered at 5v or 18-36vdc/vac or 85vac-265vac.

Which factors affect the laser projection?

The geometry of the setup, the ambient conditions and the laser itself can each affect the size and visibility of the projected laser image.
We have provided some useful information below to help you decide which model and power rating are best for you.

Our experienced sales team is also on hand to support you in finding the optimal solution for your application.

Rule of thumb: Green lasers tend to be more suitable for darker surfaces.

In general, the human eye is more sensitive to green light than red light.
Still, the surface color and structure of your object may be better suited for red lasers (see next topic).

Our sales team will be happy to help you find the option that suits you best.

There are several factors that affect the length of a laser line.

Advice: Make a sketch of the geometry.

Rule of thumb: The longer the line, the more laser power you need.

Brightness distribution

In general, a diode laser source produces an oval spot with a Gaussian brightness distribution.
Its cross section is shaped like a bell: very bright in the center, with its brightness decreasing towards the edges.
This brightness distribution is expanded by optical means to generate a line. Thus, if you mount a line laser perpendicular to a surface, the brightness of the line will be strongest at the center and decrease towards its ends (exception: lasers using non-Gaussian optics.).
The line ends as it reaches the end of the opening angle, or if the ambient light is brighter than the line.

Angle to surface

The brightness distribution changes if the laser is not mounted perpendicularly to the surface. As the line approaches the laser, it becomes brighter before reaching its maximum. After the maximum, the brightness decreases over a longer distance, depending on the angle.
For low mounting positions, Optolas offers the line lasers with special optics and an exit angle of 45° to the housing. The laser line starts directly below the housing and continues with nearly consistent brightness until the end of the line. The overall length depends on the distance to the surface.

Opening angle

The line will be short close to the surface and become longer as the distance to the surface increases. This is a geometric principle known as the “intercept theorem”.
The brightness of the line is reduced as the same laser power is distributed over a longer line. The same applies to crosshairs. Points tend to maintain their brightness if the laser can be refocused.
After a certain distance, lines and points can no longer be focused; lines get wider and points get larger while both decrease in brightness. The maximum distance for getting a sharp line, crosshair or point is about 30 m.

Laser power

The higher the power, the longer the line will be brighter than the environment and thus remain visible
