The F-Theta Lens is designed to provide a flat field on the image plane for scanning and engraving applications where a high power laser and set of rotating mirrors are used to scan across a given field. SpecificationsScrew Size M85×1Best mirr...

The lens kits consist of four basic types of lenses with various focal lengths. Focal lengths of plano-concave lenses range from -50 to -300 mm, biconcave lenses from -25 to -200. Plano-convex and biconvex lenses cover a focal distance from 25 to 100...

Cylindrical lenses with negative focal length expand light in one dimension only. They are used in laser scanners, spectroscopy, dye lasers, acousto-optics, optical processors or other applications. They are also irreplaceable for circularization of ...

Cylindrical lenses with positive focal length condense light in one dimension only. They are used to focus light to a thin line for effective harmonic generation in nonlinear crystals, in laser scanners, spectroscopy, dye lasers, acoustooptics or oth...

Short pulse laser (SP laser) and ultra short pulse laser (USP laser), have special demands on optical elements. SP lasers emit narrowband light with a bandwidth of approx. 1 nm. As the peak power can be very high, non-linear effects (color centers, s...

Our ƒ-theta lenses have been optimized for galvanometer scan systems, i.e. beam deflection systems where the scan mirrors have a certain separation from each other. The aperture stop given in the data lists, is the position where the scan mirror...

Telecentric ƒ-theta lenses provide a perpendicular angle of the laser beam onto the image surface. This is necessary for drilling holes and structuring the surface. Besides lenses made of optical glass which are suited for a large field of appli...

Standard telecentric ƒ-theta lenses are suitable for all high-power-laser applicationslike welding, cleaning and structuring.Thermal lensing, leading to a focal shift, willbe minimized.
