Gugolz Optical Polishing Pitch is offered in five grades for polishing CaF2, germanium, quartz, ZnSe, ZnS, silicon, and other materials. Made from an all-natural wood resin, it has melting points from 52° to 87°C. Users can exactly match the pitch to their optical substrate without screening, filtering, and mixing additives.

FIGURE 1. These freeform optics were designed in LightTools (a). The software can help identify manufacturing tolerances for tailored surfaces used in freeform optics for illumination. Head models are created from image data using Synopsys Simpleware software (b). Simpleware can be used in conjunction with LightTools to run detailed optical scenarios in 3D anatomical models for biomedical applications.

A photonic crystal (PhC) with a heterostructure cavity achieves double resonance even though it has only one bandgap, not two; the second resonance is provided by a “bound state in the continuum” (BIC). The heterostructure cavity includes a core, a transition region, and an outer region (delineated here by dotted lines). The relevant resonant mode is confined to the core region. Creating such a PhC out of a nonlinear optical material allows PhC-based optical frequency doubling for the first time.
