High Performance Multi-Element Laser Objective Lenses

This series of objective lenses has been specifically designed for laser beam delivery systems requiring diffraction limited performance and small spot sizes. All of the lenses feature a large clear aperture (low F#), which permits them to be used with expanded beams. All are air spaced multi-element assemblies, optimized through computer design, and are constructed of high damage optical materials. Each assembly is highly damage resistant A/R coated to minimize loss of power and contrast. Two lens types are available, apochromats and aplanats. The apochromats are unquestionably the finest objectives available for high power laser beam delivery, when high resolution coaxial CCTV viewing is used. They combine the apochromatic color correction found in the highest quality microscope objectives with the focusing performance and damage resistance required for high powered lasers. They are ideally suited for precision laser micromachining and other demanding applications. When viewing resolution is less critical, the aplanats offer an economical alternative. The two element fused silica design minimizes spherical aberrations and coma, allowing diffraction limited performance. These lenses give vastly superior performance compared to conventional and "best form" single element lenses. Maximum benefit from these lenses can be derived by using them with U.S. Laser's high quality upcollimators and beam delivery systems with integral coaxial CCTV viewing (N1001 Series). Special lens design and fabrication is also available, contact U.S. Laser sales department.

Single Element Best Form And Plano Convex Lenses

These lenses are available either plano-convex or "best form" , which provides the best possible aberration correction for a single element lens. All lenses are fused silica and high damage resistant A/R coated for use at 1064 nm. Consult sales for coatings at other wavelengths. 1" dia. lenses are also available mounted in a 1.375" dia. black anodized cell with 1.125-32 threads; 1.75" dia. lenses are available in a 2.00" dia. black anodized cell with 1.750"-32 threads, add "-M" to the part number. Consult sales for availability of coatingsat other wavelengths.
