Substrate for mounting optical parts, method of manufacturing same, and assembly using the substrate

A method of manufacturing a glass substrate for mounting optical parts on which a plurality of optical parts having different diameters is mounted so that the optical parts are specifically positioned, comprising:

• forming a groove for securing a first optical part,
• forming V-shaped grooves on either side of the groove for securing a first optical part, and
• grinding a groove for securing a second optical part while correcting the grinding conditions so that the center of the groove for securing a first optical part corresponds to the center of a virtual groove calculated so that outer tapered sections of the V-shaped grooves become outer grooves of the virtual groove.

An assembly comprising

• a glass substrate for mounting optical parts on which a plurality of optical parts having different diameters is mounted so that the optical parts are relatively positioned, comprising:
• a groove for securing a first optical part having a relatively small diameter among a plurality of optical parts, V-shaped grooves formed on either side of the groove for securing a first optical part, and
• a groove for securing a second optical part formed so that outer tapered sections of the V-shaped grooves become outer grooves for securing an optical part having a relatively large diameter among a plurality of optical parts, and a plurality of optical parts mounted on the substrate.
