A laser emits, naturally, in a rectangle-ellipse or point, but with the appropriate optics and a lot of love (if you want to do things well, like our manufacturer Osela) you will get line and pattern emissions, that is, structured light laser.
The use of diffractive or refractive optics (DOEs: Diffrative Optical Elements) allows to generate different patterns on laser emission such as lines, meshes, crosses, circles ... There are even random pattern lasers that emit a network of random illuminated points (Random Pattern Projector - Laser RPP).
3D machine vision is the field of greatest use of line lasers (artificial or machine vision lasers). Here, you should pay attention to the linewidth, the work field or the opening angle. We can offer up to 7 different optics to ensure that you have the most suitable laser for your application. In addition, it can optionally have straightness and line homogeneity improved, cosine correction to put more light at the ends, telecentric lasers...
According to the application it will be advisable the use of:
- violet line or pattern laser
- blue line or pattern laser
- green line or pattern laser
- red line or pattern laser
- infrared (IR) line or pattern laser
