SigmaLine Laser
The SigmaLine Laser represents the next generation of illumination technology for machine vision applications. Osela’s patented design delivers multiple advantages over conventional laser line projectors, providing superior performance needed for high resolution sensors.
- Patented speckle reduction technology
- Near-perfect laser line straightness
- Increased output power for a given safety class
- Multi-angular incidence illumination for challenging imaging of reflective surfaces
- Electrically efficient solution with no moving parts
- High focusing quality
Speckle Reduction Technology
Osela’s patented speckle reduction technology cuts speckle noise by up to 70% with no moving parts. This allows for more accurate optical data capture while maintaining high reliability.
Straightness: Near-perfect Laser Line
Projects laser lines with less than 0.01% deviation from best-fit line over length, allowing for higher accuracy and precision in 3D machine vision systems.
Safetyclass: Maximizing Output for a Given
The unique optical design of the SigmaLine Laser allows for significant gains in output power for a given safety class.
Scatter: Multi-Angular Incidence Projection
The multi-angular illumination along the laser line allows for enhanced light capture, particularly useful for imaging shiny surfaces.
Sharp: High Quality Focusing Performance
Osela’s patented purely optical design allows for sharp, well-defined laser lines at the focal plane and within the depth of field. Multiple diffraction limited focusing performance options are available.
Laser Diode Models and Focusing Options
At Osela, we provide many different focusing options giving you the flexibility to choose the one that best suits your application. The SigmaLine Laser has the unique capability of diffraction limited focusing for a speckle reduced solution. From the graphs below, note the beam size and depth of focus (DOF) values and then multiply by the K constants for the laser diode model and focus option of choice (A2, B2, D2, E2, or Q)
Example: From the graphs at 400mm distance, Focus = 140um, DOF 36mm. For laser model 450nm 60mW, the line thickness for focus option A2 will be 104um (140um x 0.74). The depth of focus will be 31.3mm (36mm x 0.87).
