Cavity super optic sn s2400001 part # m2, a flat HR 775 1% 1550 0ppm.

Part m2 serial number 16 is being opened and is going to the m3 slot. The orientation of the labels on the mirrors and how it looks on the optics table is flipped. When looking at the cavity on the optics table, we've been calling M3 the bottom left mirror. This is actually the part labelled M2. See this for labelled picture.
