The λEqualizer was developed using a WSS (wavelength selective switch) technology in fiber-optics and the LCOS based SLM (spatial light modulator) technology. An arbitrary spectral light passed from the λEqualizer can be applied for various emulations and calibrations of light sources.
■Optical attenuation range：>15dB
■Various emulations and calibrations
An ultra-broadband spectral equalizer is very important in various industrial applications such as astrophysics, spectroscopy and laser sensing applications.
