d2thdr,

I finally gave up entirely on the Surgitels and those idiotic and weighty Er clip-ins and went with Orascoptic TTL loupes with custom inserts for soft sleeves over the loupes. Got the plastic Er frequency blanks from one of the manufacturers that shall remain nameless and had a local optometrist’s office cut the blanks to fit. For about &#3650 I have enough cut inserts for originals and two replacements–much less than what they want (ca. &#36300) for the leaden clip-ins.

Yes, there has to be several better ways of providing adequate and safe eye protection when using lasers, especially the Er freqs that are readily absorbed in water.

Happy Holidays!

Joe
