Absorption properties of the neonatal skin-mimicking phantoms at 450 and 550 nm.

Phantom	µa 450 nm (mm−1)	µa 550 nm (mm−1)	Mimicked TcBa (µmol/L)	Mimicked TcBb (mg/dL)
F1	0.54	0.34	0.5	0.03
F2	0.97	0.34	55.8	3.2
F3	1.54	0.35	108.5	6.3
F4	2.13	0.35	143.4	8.3
F5	2.70	0.36	164.0	9.5
F6	3.28	0.36	181.3	10.5

Scattering properties were constant for all phantoms (µ_s′ = 2.00 mm⁻¹ at 450 and µ_s′ = 1.63 mm⁻¹ at 550 nm).

^aMimicked TcB is the average measure TcB over all meters.

^bFor those readers who are more familiar with bilirubin concentrations in mg/dL, we also display mimicked TcB in mg/dL. Conversion factor 1 µmol/L = 0.058 mg/dL bilirubin.
