Spatial calibration of custom-made laboratory HSI system. Distance on the Ronchi grid x that spans n pixels for each objective lens gives the size of the pixel ∆x on the image plane. Calibration is performed for 2× binning along the spatial direction.

Objective	x (mm)	n (px)	Δx (mm)
17 mm (1.0 lp/mm)	50	401	0.12
17 mm (0.5 lp/mm)	50	401	0.12
50 mm (1.0 lp/mm)	38	1173	0.03
50 mm (0.5 lp/mm)	39	1205	0.03
