First light galaxies have predictable linear clustering, and are expected to produce fluctuations with a character-istic spatial power spectrum, which peaks at an angular scale of ~ 10 arcminutes and in the 1―2 μm spectral regions. The Cosmic Infrared Background ExpeRiment 2 (CIBER2) is a dedicated sounding rocket mission for measuring the fluctuations in the extragalactic infrared background light, following up the previous successful meas-urements of CIBER1. With a 28.5 cm telescope accompanied with three arms of camera barrels and a dual broad-band filter on each H2RG (λc = 2.5 μm) array, CIBER2 can measure 6 bands of wide field (1.1 × 2.2 degrees
