New IP-n162 photoresin
High refractive index printing material for microoptics
Nanoscribe introduces the new IP-n162 photoresin for printing refractive 2.5D and 3D microoptical elements with enormous design freedom. The printing material features a high refractive index of 1.62, which expands the opportunities in creating innovative miniaturized optical systems by means of 3D Microfabrication.

3D microoptics with innovative designs
The IP-n162 photoresin is designed for high-precision additive manufacturing of polymer microoptics. Refractive optical elements printed from IP-n162 yield a higher refractive index and a lower Abbe number compared to other printing materials for 3D Microfabrication by Two-Photon Polymerization. IP-n162 fits perfectly into additive manufacturing with Nanoscribe’s 3D printers and is compatible with the 3D Microfabrication Solution Set Medium Features.

High refractive index photoresin with n = 1.62 at 589 nm
Low absorption at 1200-1550 nm for infrared microoptics
Low Abbe number and high dispersion
Combined with IP-S, suitable for printing of achromatic microoptics

Prototyping of high refractive index microoptics
IP-n162 has a high refractive index of 1.62. Among Nanoscribe’s 2PP resins, the new printing material not only offers the highest refractive index but also the highest dispersion, at an Abbe number of 25. The optical properties of printed structures are therefore close to optical polymers typically used in injection molding, e.g. polycarbonate or polyesters. This allows easy and quick prototyping of microoptics, helping to avoid expensive iterations of diamond-milled injection molds.
