A new line of fused silica fiber lenses that eliminate the need for users to send their laser heads back to the OEM for lens replacement has been introduced by Laser Research Optics.
Laser Research fused silica fiber lenses are offered in 1.5”- and 2.0”-dia. sizes with anti-reflective coatings on both sides to provide transmission of > 99.5% @ 1.06 microns with > 80% @ 650 – 670 nm. Suitable for replacement by the laser operator rather then sending the entire laser head back to the OEM, this saves up to 80% the cost of a typical lens replacement.
Designed for use as debris shields on 400 kW or higher power lasers, the fused silica fiber lenses have a 10-5 scratch-dig finish and 1/4 wave transmitted wavefront. Since laser heads often require replacement many times per month, self-replacement of the lenses minimizes downtime.
