The suffix "Pico" derives from the metric prefix for (10^-12), but in instrumentation, it signifies extreme miniaturization—smaller than micro or nano. A G2V Pico instrument would be a or a printed circuit board observatory , weighing under 100 grams and measuring a few centimeters across. It would integrate three key components: a diffractive lens or miniature all-reflective telescope (like a MEMS deformable mirror), a micro-spectrograph based on arrayed waveguide gratings (AWGs) or a digital micromirror device (DMD), and a photon-counting CMOS or avalanche photodiode array.
