multistripe array
A monolithic laser diode incorporating multiple coupled emitters.
Munsell Book Of Color
A collection of color samples arranged in charts according to equal visually spaced steps in Munsell hue, value and chroma.
Munsell chroma
Numerical scale of chroma devised by A.H. Munsell and exhibited in the Munsell Book of Color.
