missed the recent groupbuy and could use a pair or two of the cylinder lenses for a project that should impress.
The C-Lenses from LSP...I believe are BBar AR coated...SOOOooo...you can expect about approx. 1% loss...for each lens....so....a total pf 2% power loss !!dave at lasershowparts doesnt even have a data sheet for the efficiency of his lenses.
opt seems to have a quality product but at $60 plus shipping i'll keep looking.
