Wholesale 50x50x50mm K9 Optical Crystal Cube Blanks

Description

High-Purity Optical K9 Crystal for Precision Sub-Surface Laser Engraving (SSLE)

Our 50×50×50mm K9 crystal cube blanks are manufactured using optical-grade borosilicate glass, offering a refractive index of n_d = 1.5168 and high light transmittance above 91.5%. Specifically engineered for Sub-Surface Laser Engraving (SSLE), each block undergoes strict thermal annealing to eliminate internal stress, ensuring zero micro-fractures, impurities, or bubbles during high-speed green (532nm) or UV (355nm) laser processing. This 2-inch cube format serves as the industry standard for entry-level 3D crystal gifts, souvenir items, and laser equipment testing.
