Abstract: A mid-infrared objective lens assembly (10) includes a plurality of spaced apart, refractive lens elements (20) that operate in the mid-infrared spectral range, the plurality of lens elements (20) including an aplanatic first lens element (26) that is closest to an object (14) to be observed. The first lens element (26) has a forward surface (36) that faces the object (14) and a rearward surface (38) that faces away from the object (14). The forward surface (36) can have a radius of curvature that is negative.

Abstract: Spectrally analyzing an unknown sample (10A) includes (i) providing a spatially homogeneous region (10B) of the unknown sample (10A); (ii) directing a plurality of interrogation beams (16) at the spatially homogeneous region (10B) with a laser source (14), (iii) acquiring a separate output image (245) while the unknown sample (10A) is illuminated by each of the interrogation beams (16) with an image sensor (26A); and (iv) analyzing less than fifty output images (245) to analyze whether a characteristic is present in the unknown sample (10A) with a control system (28) that includes a processor. Each of the interrogation beams (16) is nominally monochromatic and has a different interrogation wavelength that is in the mid-infrared spectral range.

Abstract: An imaging microscope for spectrally analyzing a sample includes (i) a laser source that generates an interrogation beam; (ii) an attenuated total reflection assembly that includes an ATR crystal and a sample holder that holds the sample in intimate contact with the ATR crystal; (iii) an objective lens assembly that collects a reflected beam and focuses the reflected beam; and (iv) a two dimensional image sensor that receives the focused, reflected beam and captures two dimensional image information that is used to generate an image of the sample, the image sensor being operable in the mid-infrared range.
