Abstract:
A method of producing a microlens on a substrate comprising the steps of:a) preparing a carboxylated silicone precursor composition;b) applying the carboxylated silicone precursor composition to a surface of a substrate to form a precursor droplet; andc) thermally oxidizing the precursor droplet to form a microlens, said silicone precursor composition selected from the group consisting of vinyl containing polygermanosiloxane ##STR9##wherein R.sub.1 through R.sub.6 are selected from the group consisting of alkyl and alkene groups and R.sub.7 is a vinyl group and carboxylated polygermanosiloxane ##STR10##wherein R.sub.1 through R.sub.5 are alkyl groups and R.sub.6 is an alkyl radical.
