K WONG

No, a standard thin-film optical interference filter cannot be angle-tuned to shift to a longer (redder) wavelength. Tilting an interference filter away from normal incidence (0°) will always shift its...

K WONG

Reflected Wavefront Error (RWE) in interference filters refers to the distortion or deviation of a light wave's phase after it reflects off the surface of the filter. In an ideal...

K WONG

No. In fact, the opposite is generally true. For thin-film optical filters, the Continuous Wave (CW) Laser-Induced Damage Threshold (LIDT) is typically lower within the passband (the transmission region) than...
