High-performance F-Theta objective lenses for demanding applications in laser material processing

Silverline^TM F-Theta lenses from Jenoptik have been specially developed for applications that require high-power lasers and short-term pulses. These lenses consist of low-absorbing, full quartz glass to offer particularly high laser power. They are available for wavelengths of 266 nm, 355 nm, 1030...1080 nm or 900...1100 nm.

The Silverline^TM F-Theta lenses limit diffraction and produce a high image quality. They are also highly resistant to damage and provide high spot consistency over the entire scanning range. With beam power of up to four kilowatts, the Silverline^TM lenses do not require active cooling and guarantee a minimal focal point shift for high-power lasers.

Specifically, the Silverline^TM F-Theta lens 170-355-140 covers the 355 nm range. It has a low maximum telecentric angle of only 4.9 degrees and a homogeneous spot size distribution over a working field of 100 x 100 mm. This large working field combined with diffraction-limiting imaging quality enables increased output in comparison to conventional lenses ensured by our innovative, patented mounting technology.

With the new JENar^® APTAline^® series, we offer lenses that are optimally tailored to customers' requirements. This means that we respond to the constantly changing requirements of the industry and increase the possible range of applications with the APTAline^® series.

These quartz glass, high-power lenses offer a cost-optimized alternative for demanding applications where reliability, series stability and durability count. They are available for wavelengths of 1030...1080 nm. The APTAline^® lenses are based on proven mechanical and optical designs and are subject to the same high-quality standards as our other F-Theta products.

The F-Theta JENar^® lenses are suitable for uses in micromaterial processing, especially for microstructuring or for marking and labeling different materials.

The JENar^® series is used for laser wavelengths in the UV, VIS or IR range, but they are also available for wavelengths from 355 to 1080 nm. The standard lenses are produced with protective glass and are extremely durable.

These lenses can be quickly and easily integrated into any system using the available STEP files. Each lens undergoes a standardized application-specific test, which ensures consistency of the optical properties during series production. This makes it easy to replace lenses, and customer benefit from an increased product lifecycle.
