Ultra-High Linear Precision 515nm Green Laser Line Generator For Scientific Research Whatever kind of working surface users are in need of ultra fine and clear line indication in scientific research fields, not relying on manual or mechanical line aligning works, it makes a good job to operate a Berlinlasers 515nm green laser line generator for scientific research works. It projects ultra fine and straight forest green reference line from a qualified glass coated lens within 10 to 110 degree, together with adjustable focus optic lens design in front of laser beam aperture, it ensures ultra high fineness and high linear precision forest green line projection within 0.5 meter to 6 meters length. Being made with ultra compact size and durable structure design, laser line generator allows quite easy installation or integration within scientific research machine or device, which makes sure of noncontact and no mistake green line projection onto different working surfaces. The straightness error is less than±0.1mm. This meets the micrometer-level benchmark requirements of scientific research experiments and reduces experimental data deviation. When it gets correct use of output power and optic lens fan angle, green laser line alignment assures no mistake measurement for optical and photonics research, and materials science experiments etc. https://www.berlinlasers.com/515nm-5mw-50mw-green-laser-line-generator
