Does any one know of any suitable dyes other then Pinacyanol to sensitize silver halide emulsion to red laser 632.8 nm ?

3-carboxymethyl-3',9-diethyl-5,5'-dimethylthiacarbocyanine betain (it used to be available from
www.organica.de/en/products/dyes/) might be a good alternative for Pinacyanol.

3-carboxymethyl-3',9-diethyl-5,5'-dimethylthiacarbocyanine betain dye is not matched in ORGANICA
