What Is a Meniscus Lens?
A meniscus lens is a curved optical lens with one concave surface and one convex surface, designed to reduce spherical aberration while maintaining focusing or beam-shaping capability.
Meniscus lenses are commonly used when:
Image quality is critical
Aberration control is required
Optical systems need improved performance without complex multi-lens assemblies

Material & Coating Options
Materials
Optical glass (BK7 etc.): standard visible applications
Fused silica: UV/NIR, laser durability
IR materials (Ge / ZnSe / ZnS / Si): infrared systems (custom)

Coatings
AR coating (single wavelength): lowest reflection at target nm
BBAR: broadband wavelength range
Dual-side AR: improved transmission & contrast
Laser-grade coating: enhanced durability for laser applications
