Jenoptik strengthens focus on future markets with new F-Theta lens for 3D printing

Jenoptik, a leading provider of optics and laser technology, is following up two new lenses specifically for laser structuring of solar cells with another new lens that is specially designed for the high-precision creation of complex structures in 3D printing, particularly in selective laser sintering (SLS).

Precision meets performance

The new F-Theta lens JENar^TM-APTAline^TM-639-1030...1080-580-AL is designed for wavelengths of 1030 ... 1080 nm and has a focal length of 639 mm. It has a scan field of 410 mm x 410 mm and offers excellent spot homogeneity across the entire field thanks to its optimized optical design.

“We are proud to introduce a new F-Theta lens for the 3D printing market that meets the highest requirements for precision and quality,” says Dr. Maria Oliva, Vice President Business Management of Jenoptik’s Semiconductor & Advanced Manufacturing Strategic Business Unit (SBU). “Our aim is to offer our customers the opportunity to produce high-quality products that meet the requirements of future markets.”

Designed for selective laser sintering (SLS)

The SLS process requires a high degree of precision and accuracy. A plastic or metal powder is applied layer by layer and the powder particles are melted with a laser at the desired points to form a solid structure. The F-theta lens plays a key role here, as it focuses the laser beam onto the printing surface over the entire working area with limited diffraction and high precision.

The JENar^TM-APTAline^TM-639-1030...1080-580-AL offers laser system manufacturers and integrators a durable and reliable lens that is also suitable for high-power lasers or ultra-short pulse laser applications thanks to its quartz glass optics, high-quality coating and minimized back reflections. This makes it ideal for high-precision laser processing technologies such as selective laser sintering (SLS) but can also be used in other fields of application.

Application-specific product range & expanded capacities

Jenoptik has steadily expanded its range of F-theta lenses in recent months to include new specific applications. These include the high-power F-theta lens for high-precision laser structuring for solar cells (JENar^TM Silverline^TM 340-355-332-S), the ready-to-integrate Modular Beam Splitting System (MBSS) for the solar cell production process, and an F-theta lens with a very large scan field (JENar^TM 340-1030…1080-255-AL), which can be used for plastic and metal welding, among other things.

In the second half of 2024, Jenoptik expanded its production capacities for F-theta lenses in China and Europe, thereby significantly increasing its proximity to its customers and also considerably reducing delivery times.

Jenoptik will present the new F-Theta JENar^TM-APTAline^TM-639-1030...1080-580-AL to trade visitors at the Laser World of Photonics trade fair in Munich from June 24 to 27, 2025, at booth B2.119 along with other products and solutions for the semiconductor industry, life science, medical technology and metrology.
