Table 4. The OIPs OAPs owned by MEC. OAP 3 is standard for full intensity experiments. OAP 1 and 2 have too tight of an angle to use with the standard target frame, but may be used in certain customized experiments. OAP 4 is intended for frequency doubled or uncompressed experiment in which the beam size is smaller than standard. Typical use is to produce an f/10 focus.
