An imaging scanner and a method for using the same are disclosed. The scanner includes a variable attenuator adapted to receive a light beam generated by a MIR laser and that generates an attenuated light beam therefrom characterized by an attenuation level. The scanner includes an optical assembly that focuses the attenuated light beam to a point on a specimen. A light detector measures an intensity of light leaving the point on the specimen, the light detector being characterized by a detector dynamic range. A controller forms a plurality of MIR images from the intensity as a function of position on the specimen, each of the plurality of MIR images being formed with a different level of attenuation of the light beam. The controller combines the plurality of MIR images to generate a combined MIR image having a dynamic range greater than the detector dynamic range.
