Optical Glass spherical ball lenses, JGS1 glass

Optical glass ball lens( Optical glass spherical lens) is the most cost-effective and widely used micro-spherical lens.it's core material is K9.compared with sapphire and ruby, k9 glass ball lens is fully applicable to 532nm/1064nm wavelength band and has extremely high cost performance ratio. Comparison commonly glass VS Sapphire VS Quartz/JGS1 Characteristics optical glass K9 ball lens Sapphire ball lens Fused silica ball lens 532nm/1064nm transmission excellent excellent excellent Cost extremely low preferred high Medium Temperature resistance/hardness Generally softening point 550 ℃ extremely high good Damage Threshold(LIDT) Good( CW/Pulse) High Highest(ultra fast laser) Applicable scenarios The majority of laboratory optical paths high temperature/maintenance resistant probe high power/ultraviolet   Main Application Scenario * Fiber laser coupling: the most common scenario the 1064nm laser is coupled from the end of the fiber into the free space or vice versa * M…
