Beyond Injection Molding: Nanoscribe's IP-n162 Resin Opens New Possibilities in Microfabrication

Nanoscribe has released a new photoresin, IP-n162, which is designed to take the fabrication of micro-optical elements to the next level. This new material has a high refractive index of 1.62 at a wavelength of 589 nm, the highest in Nanoscribe’s resin portfolio, which allows for a high level of shape accuracy. The resin also has a low absorption rate when exposed to infrared (IR) light, making it suitable for creating IR micro-optics, and it possesses dispersive qualities that are similar to optical polymers used in injection molding, such as polycarbonate or polyesters. The new material allows for the creation of freeform shapes at a microscale, providing a cost-effective alternative to traditional fabrication methods. When combined with materials with a lower refractive index, the resin can be used to create achromatic optical systems, which can transmit light without separating it into constituent colors, potentially improving the quality of displays in devices like cameras and projectors. Nanoscribe is also working with industry partners to develop additional applications for the new resin, including healthcare-related applications
