IP-n162
With a high refractive index of 1.62, the high-performance photoresin IP-n162 expands the possibilities for creating innovative, miniaturized optical systems. IP-n162 is ideal for printing refractive 2.5D and 3D microoptical elements, offering enormous design freedom.
3D micro-optics with innovative designs
The IP-n162 photoresin is designed for high-precision additive manufacturing of polymer micro-optics. 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.

Prototyping of high refractive index micro-optics
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 micro-optics, helping to avoid expensive iterations of diamond-milled injection molds. IP-n162 is suitable for a wide range of applications that require refractive or hybrid high-performance micro-optics, for example, for miniaturized imaging systems and 3D sensing for AR/VR applications.
Prof. Qixiang Cheng, University of Cambridge
We selected IP-n162 for its high and suitable refractive index and its optimal balance between high-resolution capability and efficient fabrication speed.
Enabling achromatic and
infrared micro-optics
The photoresin features a high dispersion, expressed by its low Abbe number of 25. This is significantly different from Nanoscribe’s other photoresins and paves the way for the fabrication of compound optics consisting of elements with different dispersion. Here, IP-n162 and the lower refractive index resin IP-S can be a perfect match for creating achromatic optical systems on the microscale.
Another valuable property of IP-n162 is its low absorption in the infrared spectrum. Between 1200 nm and 1550 nm, IP-n162 absorbs extremly little. This makes this photoresin a perfect choice for infrared optics, optical communications, and photonics packaging applications where low absorption losses are critical.
