Figure 1 illustrates the test optical path for cylindrical homogeneity interferometry. The integrated TC enables rapid optical alignment via its adjustment mechanism. This lens offers advantages such ...

The optical transparency of silica glass significantly improves when subjected to compression at its melting temperature. Using a rare hydrostatic iso-pressure apparatus capable of reaching 0.98 GPa ...

The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a level of precision approaching the theoretical limit allowed by quantum ...

Hypergap materials reveal a second transparent region above the bandgap, overturning assumptions about optical limits and enabling low-loss light control, wavelength conversion, and new photonic ...

In most filled plastics, mismatches between micron-scale particles and refractive index can cause strong scattering. This shows up on a macroscopic scale as haze and loss of transmittance. When you ...
