Laser line generating lens | LNS-584
Overview
EOPTIS offers a variety of aspherical line generating lenses able to transform a pointwise laser beam into a straight line with uniform intensity distribution across the entire length.
These lenses offer significative advantages compared to other optics:
- Uniform-intensity distribution: other refractive solutions like cylinder or rod lenses do not correct for the inherent Gaussian profile of a laser beam and therefore deliver a profile with “hot-spot” centre points and fading edge.
- Continuous and crisp laser line: compared with diffractive optics, that obtain a line superimposing multiple patterns (deliver a segmented line with additional faint lines).
The output line characteristics can be selected from a list of standard items as well as tailored to specific needs. The design specs affecting the line shape can be factory-controlled to deliver a cost-effective lens that perfectly fits the laser generator and the application requirements:
- Output fan angle and working distance
- Base material (refraction index)
- Input beam wavelength, divergence and diameter
- Uniformity acceptance level.
The lens is offered un-mounted for OEM applications.
