Why choose a NanoOne Green over a 250 or 1000? What are the advantages of the 515 nm laser wavelength vs. the 780 nm?

The shorter wavelength (515 nm vs. 780 nm) leads to a significantly smaller voxel, allowing for higher resolution. A voxel carrying more energy also opens the possibility to use additional classes of polymers – transparent polymers being in the forefront. The green system delivers ~30% higher resolution than 780 nm wavelength systems, enabling feature sizes below 100 nm.

What applications are most applicable for a 515 nm wavelength laser?

The NanoOne Green model is especially well-suited for applications requiring ultra-high resolution and optical clarity. It enables cutting-edge work in plasmonics, photonics and meta-material fabrication, as well as applications that demand transparent, non-auto fluorescent materials such as microfluidics, polymer optics and biocompatible scaffolds. Ideal use cases include micro-optics, transparent medical micro-devices and structures requiring sub-100 nm resolution.

What is the difference between a 515 nm wavelength laser and a 780 nm wavelength laser?

A 515 nm laser (green) has a shorter wavelength than a 780 nm laser (infrared), which results in higher resolution due to smaller focal points. It also enables polymerization of non-fluorescent, transparent, and biocompatible materials that are not responsive to 780 nm light. In contrast, 780 nm lasers are better for high-speed throughput with traditional fluorescent materials.

What materials can I print with the NanoOne Green?

Beyond its remarkable precision, the NanoOne Green operates as an open system, enabling broad material compatibility. Leveraging its 515 nm green laser, it can print with transparent, non-fluorescent, and biocompatible resins that are often more difficult to use with 780 nm laser systems. This means it not only opens new material possibilities but also fully supports the range of standard 2PP resins commonly used with 780 nm systems for high-resolution microfabrication, including specialized materials such as UpOpto for optical clarity and BIO INX resins for biomedical and cell-safe applications.

How precise is the NanoOne Green printer?

The NanoOne Green achieves approximately 30% higher precision compared to a 780 nm wavelength machine, enabling feature sizes below 100 nm thanks to its 515 nm laser and high-NA objectives. It can produce voxels as small as 100 nm or below with surface roughness under 5 nm, suitable for demanding micro-optical and microfluidic applications.

Can the NanoOne Green be upgraded?

Yes, the NanoOne Green is a modular platform. It ships in a standard configuration but supports additional accessories such as fiber holders, wafer chucks, heatable resin vats and stage inserts for biological substrates that can be retrofitted in at any time, allowing the system to evolve with your needs.

Can my red laser system be changed to green or vice versa?

No, you cannot directly switch a red (780 nm) laser system to green (515 nm) or vice versa because they use different laser sources and optics optimized for their specific wavelengths. Each system is designed around its laser’s wavelength for resolution, material compatibility and beam delivery so changing the laser would require a different setup or a new system.

What kind of objectives are included with NanoOne Green?

The NanoOne Green includes three high-performance objectives:40× NA 1.420× NA 0.710× NA 0.4These objectives are optimized for high-resolution 2-photon polymerization (2PP) at a 515 nm wavelength, enabling feature sizes below 100 nm. Additionally, the system supports upgrades with other objectives, such as 60xN1.5, to accommodate various application needs.

Is the NanoOne Green suitable for bioprinting applications?

Yes, the NanoOne Green is suitable for bioprinting because its 515 nm laser enables printing with biocompatible, non-fluorescent resins that support cell viability. Its high resolution and material compatibility make it ideal for creating detailed biomedical scaffolds and microfluidic devices used in tissue engineering.
