What Is a Convex Lens?
A convex lens is a converging lens used to focus or collimate light.
It bends incoming rays toward a focal point and is widely used in:
Laser focusing and beam shaping
Imaging and machine vision systems
Illumination optics and projection modules
Material & Coating Options
MaterialsOptical glass (BK7 etc.): standard visible systems
Fused silica: UV/NIR & laser durability
IR materials (Ge / ZnSe / ZnS / Si): infrared optics (custom)
Coatings
AR coating (single wavelength): lowest reflection at target nm
BBAR: broadband wavelength range
Dual-side AR: improved transmission & contrast
Laser-grade coating: for higher power systems
