1. A method for performing a screening, the method comprising:
illuminating a sample with light from a screen of a system at a first wavelength while the system is at a predetermined position with respect to the sample;
capturing a first image of the sample using a camera of the system while the system is at the predetermined position and the sample is illuminated with the light at the first wavelength;
illuminating the sample with the light from the screen at a second wavelength while the system is at the predetermined position;
capturing a second image of the sample using the camera while the system is at the predetermined position and the sample is illuminated with the light at the second wavelength;
combining the first and second images to produce a multispectral image; and
measuring a spectral feature in the multispectral image.
