Industrial manufacturing with
Two-Photon Grayscale Lithography
The world’s first Two-Photon Grayscale Lithography (2GL ®) system combines the extraordinary performance of grayscale lithography with the precision and flexibility of Nanoscribe’s pioneering Two-Photon Polymerization (2PP) technology. Quantum X, as maskless lithography system, is the optimal tool for industrial manufacturing of 2.5D freeform microoptics, microlens arrays and multi-level diffractive optical elements.
Quantum X controls the voxel size along one scanning plane using synchronized laser power modulation at high speeds. In this manner, complex shapes are produced and variable feature heights are achievable within one scan field. Discrete and accurate steps as well as essentially continuous topographies can be printed on up to six-inch wafer substrates without the need for additional lithography steps or mask fabrication, thanks to Two-Photon Grayscale Lithography (2GL). The substantial design freedom of additive manufacturing by 2GL facilitates microfabrication and enables various industrial manufacturing tasks.
Quantum X is designed for rapid prototyping and mastering in industrial manufacturing and replication processes. With the performance of Two-Photon Grayscale Lithography, this maskless lithography system redefines the fabrication of freeform microoptics, microlens arrays and multi-level diffractive optical elements.
Control your print job via the device's integrated touchscreen. Keep an eye on your Two-Photon Grayscale Lithography system even from the office and in multi-system or multi-user configurations via nanoConnectX. And benefit from industrial standards and time-efficient wafer-scale batch production for outstanding industrial manufacturing.

Be ready for exceptional optical quality
Two-Photon Grayscale Lithography (2GL®) uses high-frequency synchronization of laser beam modulation and high-speed galvo mirrors for single voxel tuning, enabling outstanding microfabrication features and structures in optical quality:
Seamless structures with 2GL stitching
Quantum X uses a high-precision positioning unit and self-calibration routines to print with excellent accuracy when stitching adjacent print fields together to fabricate larger structures. 2GL enables the dynamic adjustment of laser dose at the print field boundaries to compensate chemically induced shrinkage of the photopolymer and positioning imperfections. With this combination of features, truly seamless structures can be printed over an area of several cm², eliminating all stitching marks.
Tilt compensation for smooth surfaces
Quantum X applies the automatic interface finder to detect the surface of the substrate with nanometer precision and to anchor structures reliably on the surface. It measures the substrate tilt by operating the autofocus on a tight grid of points. The tilt of the substrate is determined by processing dedicated signals while the stage is moved up and down. By using 2GL combined with the automatic tilt compensation, deviations can be equalized between individual print blocks to achieve smooth surfaces without stitching seams or staircase effects on tilted substrates.

My first print job worked flawlessly and the structure is stunningly good, if not to say sensational. I have never seen anything like this before.
Quantum X Software
How to get started with your print job
Prepare and control your print job via touchscreen or remotely
The simple and convenient workflow makes it easy to integrate Quantum X into industrial manufacturing environments and multi-user scenarios. What makes it so simple? You can upload, print, and monitor your print job directly from the device’s touchscreen or remotely from your PC. And these are just some of the reasons to connect with Nanoscribe Quantum X.
Generate your print job with GrayScribeX: In just a few steps, the print job development software guides you from creation to uploading your individual project as a proprietary .nano file to the maskless lithography system Quantum X.
Start your print job via the touchscreen: The intuitive touchscreen menu of Quantum X easily guides you to successful printing. Also benefit from essential data such as hardware information, system status and the print progress. Furthermore, a live view of the print process via three cameras gives you a visual control at any time.
Stay connected with nanoConnectX: Start and monitor your print job from the office with the remote access software nanoConnectX. The Quantum X system is therefore well equipped for industrial manufacturing environments and multi-user scenarios.
GrayScribeX is a specially developed software for creating individual print jobs for Quantum X. You can import standard grayscale images or CAD models that are automatically converted into grayscale images. A smart software routine translates the gray values from the imported design into the heights of the print object and precisely sets the calibrated print parameters.
