Title:
MANUFACTURING METHOD OF COLUMNAR OR RING-SHAPED WAVELENGTH CONVERSION MEMBER
Document Type and Number:
Japanese Patent JP2022086430
Kind Code:
A
Abstract:
To provide a method capable of efficiently manufacturing columnar or ring-shaped wavelength conversion member with high dimensional accuracy.SOLUTION: The manufacturing method of a columnar or ring-shaped wavelength conversion member includes the steps of: holding a plate-shaped wavelength conversion member on a holder 10A; forming a wavelength conversion member block 50A including a precursor 51A of a columnar wavelength conversion member by performing machining and processing the retained plate-shaped wavelength conversion member; and separating the precursor 51A of wavelength conversion member of columnar into pieces. The cutting and processing process performs a cutting process that includes at least two of roughing and finishing.SELECTED DRAWING: Figure 2
