The Nanoscribe PPGT2 system uses what is known as 2-Photon Polymerization to achieve sub-micron resolution and feature sizes. The system uses a 780nm femtosecond laser, which when passed through the objective lenses, focuses the beam to a point. At this point, the frequency doubles and the wavelength halves, causing the point to be in the UV spectrum, where our photoresists polymerize.

Yes! However, custom resins will need to be kept off of our Objective lenses, meaning no DiLL (Dip-in Laser Lithography). We would print through our borosilicate glass substrates using oil immersion or through air. With oil immersion, there would be a limit on the overall height of the printed part as well as smallest feature sizes and quality as you would be printing through oil, glass, and already polymerized resin. With air, you are limited to 2.5D Lithography.

No. Our PPGT2 system is not in a cleanroom environment.

Due to the complexity of the printing process and fragility of the Objectives, glassware, hardware, and printed samples, trained personnel will work personally with you to print your samples/ structures to your desired specifications.

Yes, with limitations. The PPGT2 system can print larger than the objective print field, however, doing so would mean that the printed part would have to be split up into smaller blocks and "stitched" together. The edges where two blocks meet can have a ridge/ indent and won't be perfectly smooth. This might be fine for most prints, but some might need this to be avoided, like for micro-optics. Ridges in a micro-optic design could be detrimental to a working micro-optic print.
