The Next Generation Balloon-borne Large Aperture Submillimeter Telescope(BLAST-TNG) is a submillimeter mapping experiment planned for a 28 daylong-duration balloon (LDB) flight from McMurdo Station, Antarctica during the2018-2019 season. BLAST-TNG will detect submillimeter polarized interstellardust emission, tracing magnetic fields in galactic molecular clouds. BLAST-TNGwill be the first polarimeter with the sensitivity and resolution to probe the$\sim$0.1 parsec-scale features that are critical to understanding the originof structures in the interstellar medium.  BLAST-TNG features three detector arrays operating at wavelengths of 250,350, and 500 $\mu$m (1200, 857, and 600 GHz) comprised of 918, 469, and 272dual-polarization pixels, respectively. Each pixel is made up of two crossedmicrowave kinetic inductance detectors (MKIDs). These arrays are cooled to 275mK in a cryogenic receiver. Each MKID has a different resonant frequency,allowing hundreds of resonators to be read out on a single transmission line.This inherent ability to be frequency-domain multiplexed simplifies thecryogenic readout hardware, but requires careful optical testing to map out thephysical location of each resonator on the focal plane. Receiver-level opticaltesting was carried out using both a cryogenic source mounted to a movablexy-stage with a shutter, and a beam-filling, heated blackbody source able toprovide a 10-50 $^\circ$C temperature chop. The focal plane array noiseproperties, responsivity, polarization efficiency, instrumental polarizationwere measured. We present the preflight characterization of the BLAST-TNGcryogenic system and array-level optical testing of the MKID detector arrays inthe flight receiver.
