The WaveEye from Laser Components is a compact wavelength meter for cw or quasi-cw lasers between 450 nm and 950 nm. The measurement data is available with a data rate of 1 kHz without a warm-up delay. It can be used for an optical input power range between 0.1 µW and 1 mW. The wavelength information is available as a voltage of up to 4.096 V at the analog output. It is ideally suited as an OEM component and is used for applications like spectroscopy, tunable lasers, characterization of diode lasers and gas detection. The WaveEye is operated with a USB cable via the supplied software interface or via text-based commands. The USB connection also serves as a power supply.
