The present invention relates to the use of lead-free and phosphate-containing glasses, preferably colored and filter glasses which absorb light in the infrared region (IR-region), in a precision molding process. Preferably, the content of fluorine in the glass is low. Advantageously, so optical constituents can be produced without finishing, such as for example lenses for digital cameras. By the use according to the present invention, also other optical constituents can be produced which can be directly used for a corresponding technical purpose. For an advantageous use, the optical constituents produced by precision molding can be used in the fields imaging, projection, telecommunications, optical communications engineering and laser technology.
