Jenoptik F-theta Lenses for Laser Material Processing at 355, 515–540, and 1030–1080 Nanometers

30 Jul 2020

Jenoptik offers a broad portfolio of fused silica lenses for high-power applications for example with its Silverline lenses for applications with wavelengths of 355 and 515–540 nanometers. Low-absorption fused-silica and optimized coating combined with improved reflex positions enable the lenses to be used with ultrashort laser pulses. Various application tests confirmed the performance of the lenses.

The F-theta lens for 355-nanometer applications can be used for a wide range of applications and materials. The short-focus lens enables a small spot diameter in a scan field of 22 millimeters. Depending on the application, spot sizes of up to 4.5 micrometers can be realized. This lens is particularly well suited to high-volume series production in microtechnology, microsystems technology, and the consumer electronics sector.

Another F-theta lens for applications in the wavelength range of 515–540 nanometers has been designed for manufacturing methods using high-energy fiber lasers and disk lasers with a high beam quality. In this wavelength range, the lens can also be used specifically to process copper and brass, for example for processing electronic components and circuit boards, or for additive manufacturing. With a focal length of 115 millimeters, workpieces can be processed in a scan field of up to 71 millimeters. The lens’s performance is demonstrated by successful application tests conducted with a Jenoptik JenLas® femto 16 laser system at a wavelength of 515 nanometers with a maximum pulse energy of 60 microjoules and pulse lengths of 600 femtoseconds.

With its JENar® lens family Jenoptik also offers a lens for applications in the wavelength range of 1030–1080 nanometers. The lens is designed for marking, structuring, and engraving plastics and metals and for structuring solar cells. It has a large scan field of 254 x 254 millimeters and a focal length of 347 millimeters, and is optimized for back reflections.
