F Theta BEN Lens

F-Theta JENar™ Silverline™ 340-355-332-S (order no. 663830)

High efficiency and optimal process results

The Jenoptik high-power F-Theta lens JENar™ Silverline™ 340-355-332-S is specially designed for UV applications in the wavelength range of 340-355nm.
It can achieve particularly small spot sizes of up to 17 µm – and that with a large scan field of 235 by 235 mm. In this way, very small structures in the micrometre range - as required for the production of G12/M12 cells (size of 210 x 210 mm) - can be realised very efficiently and quickly. Excellent LIDT values also ensure that the high-performance objective lens works reliably in demanding applications such as laser structuring using ultra-short pulse lasers. A sophisticated optical design and high quality standards in manufacturing ensure reliable and homogeneous results across the entire working field.

This high-performance fused silica objective lens is based on the proven Jenoptik´s mechanical and optical design and subject to the same high-quality standards.
Special low-contamination mounting technologies and the assembling in certified clean room makes this F-Theta lens extremely durable.


  • Realizes small spot sizes down to 17 µm
  • Large scan field with a diameter of 332 mm
  • Excellent LIDT-Values make it the optimal choice for ultra-short-pulse laser applications
  • Extreme durable due to sophisticated mounting and assembling
  • High damage threshold thanks to low-absorption anti-reflective coating

High-power objective lenses F-Theta JENar® Silverline™ Series 

F-Theta JENar® Silverline™ objective lenses for wavelengths from 355 to 1080 nm

F-Theta new Silverline objective lens group

F-Theta JENar® Silverline® serie

SilverlineTM 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 SilverlineTM 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 SilverlineTM lenses do not require active cooling and guarantee a minimal focal point shift for high-power lasers.

Specifically, the SilverlineTM 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.
