Optoelectronic components made of the semiconductor material silicon are sensitive to light with wavelengths ranging from the ultraviolet (UV), visible light, to near-infrared radiation (300-1100 nm).

Laser-line bandpass filters, fabricated from a "hard" ion-beam sputter technology, give >90% transmission at the design laser wavelength and block >5.0 OD at just ±2% of the laser wavelength.
