Laser line generating lens LNS-584

Product catalog summary

User Benefits and Applications
EOPTIS offers aspherical line generating lenses that transform a laser beam into a straight line with uniform intensity. These lenses provide advantages such as uniform intensity distribution and continuous laser lines, unlike other optics that may have hot spots or segmented lines. Applications include alignment, machine vision, 3D contour mapping, high-speed industrial inspection, process control, and measuring systems.

Specifications
The lenses can be customized for output fan angle, working distance, base material, input beam wavelength, divergence, and diameter. They are available un-mounted for OEM applications. The LNS-584 model offers fan angles from 10° to 90°, with substrate materials like N-BK7, N-SF5, and N-SF6. The input beam diameter ranges from 0.8 to 4.0mm, and wavelengths include 532nm for green lasers and 635, 650, 670nm for red lasers.

Ordering Information
Various configurations are available, such as:

LNS-584.P001A: 90° fan angle, 2.0mm beam diameter
LNS-584.P004A: 60° fan angle, 2.0mm beam diameter
LNS-584.P007A: 45° fan angle, 2.0mm beam diameter
LNS-584.P010A: 30° fan angle, 2.0mm beam diameter
LNS-584.P006A: 60° fan angle, 4.0mm beam diameter

Fan angles are specified at 660nm, with other wavelengths and configurations available upon request.

Technical Details
The lenses feature a uniform intensity distribution lengthwise and Gaussian widthwise, with a surface quality of 80-50 Scratch/Dig and surface flatness of λ/2 at 635nm. The diameter is 9.0±0.1mm, height ranges from 7.0 to 9.0mm, and the clear aperture is approximately 90%. The mass is around 8g.

Company Information
EOPTIS designs and manufactures vision systems and optoelectronic instruments for industrial, biomedical, security, and food sectors, offering both off-the-shelf and custom OEM solutions.

Catalog excerpts

Laser line generating lens LNS-584 User’s benefits Ÿ Excellent line quality Ÿ Beam tailored solutions Ÿ Various wavelengths and fan angle available Alignment and positioning Machine vision 3D contour mapping High-speed industrial inspection Process control Measuring systems 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: Ÿ 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. Ÿ Continuous and crisp laser line: diffractive optics obtain a line superimposing multiple patterns and therefore deliver a segmented line without 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 perfectly fitting the laser generator: Ÿ Ÿ Ÿ Ÿ 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. Ordering information Fan angle specified at 660nm.
