The new GONG Turret Windows are here!

 Five new windows arrived this week from Asahi Spectra.


 The windows will be tested at the Boulder "TE" GONG after we've wrapped up the LCVR and UV Blocker tests. The test coupons for the two witness samples (AR Coating & Bandpass Coating) will be shipped to the DKIST optical lab in Maui for testing.
