Abstract: An optical system, comprising a multi-spectral optical element, a switchable filter, a dual bandpass filter, and a sensor. The multi-spectral optical element receives light in at least a first spectral band and a second spectral band. The dual bandpass filter filters out wavelengths of light in a transition region of the switchable filter between the first spectral band and the second spectral band. The switchable filter filters light received from the dual bandpass filter in the first spectral band in a first mode where the switchable filter transmits light in the first spectral band and in a second mode where the switchable filter does not transmit light in the first spectral band. The sensor is disposed at an image plane, and the multi-spectral optical element is configured to produce a modulation transfer function value that is a above a predetermined threshold for each of the spectral bands.
