The laser radiation was coupled into a Zeiss microscope through a wavelength-specific single-mode optical fibre.
The quantum well active region of the VCSEL was optically pumped at 980 nm through a wavelength-division multiplexer and wavelength tuning was performed by electrostatic deflection of a MEMS tunable filter.
The resultant powder was pressed into a pellet and FTIR was performed on a Bruker Vector 22 thermal gravimetric infrared spectrometer (TGA-IR) through transmission with a wavelength of 633 nm and in the range of 400 to 2000 cm−1.
The bacterial suspension was estimated turbidimetrically by comparing the newly grown bacterial suspension with known standards through spectophotometry at a wavelength of 625 nm, in order to obtain a culture of the desired bacterial density.
The hematite electrodes were able to generate incident photon-to-current efficiencies (IPCEs) of ∼8% by illumination through the substrate with a wavelength of 350 nm and a light intensity of 0.1 mW cm−2 without any applied voltage.
The object itself has no color; it shows color through a different wavelength of light absorption, reflection, and projection.
In EPR mode, the resonator functions as a one-loop-two gap resonator, electrically coupled through a half wavelength inverter.
With the biggest mirror yet flown in space, Europe's new Herschel Space Observatory will peer through a new wavelength window at the cool regions of the universe.

The figures show that absorbance edges are shifted through a larger wavelength (smaller energy) with respect to higher heat treatment time or temperature due to quantum confinement effects.
