Silverline? F-Theta Objective Lenses for High-Power and Short-Pulse Lasers

Silverline™ F-theta objective lenses from Jenoptik have been specially developed for applications that use high-power and short-pulse lasers. They are fused silica objective lenses that offer minimal absorption for extremely powerful lasers. The F-theta objective lenses in the Silverline™ series are available for applications from 1030 to 1080 nanometers, from 900 to 1100 nanometers, 355 and 266 nanometers.

The objective lenses are diffraction-limited and provide a high level of image quality. They also offer a significantly higher damage threshold and a high spot consistency over the entire scanning range. The Silverline ™ objective lenses can handle a beam power of up to four kilowatts without active cooling. They guarantee a minimal focus shift for extremely powerful lasers. We offer the F-theta objective lenses as a standard selection or can adapt them to meet your exact requirements.

The F-theta Silverline™ lens 170-355-140 in the wavelength-range of 355 nm. It has a maximum telecentric angle of just 4.9 degrees and a highly homogeneous spot size distribution across the whole of the 100 x 100 mm work area. This large processing area, in combination with the diffraction-limited image quality, allows for increased throughput in comparison with standard lenses available on the market. We can ensure the level of precision necessary here by means of the high-quality optics employed, a new patented mounting technology.

Each objective lens undergoes a standardized application testing procedure. This guarantees highly consistent optical properties throughout series production.
