Plano Concave (PCV) Lenses

Applications

Widely employed in precision optical systems requiring negative focal power: laser beam expanders/focusers, infrared imaging modules, sensor protection windows, and industrial inspection equipment. Ideal for applications demanding compact design with controlled light divergence.

Key Features

Manufactured from K9 crown glass (standard refractive index nₐ=1.5168), featuring a flat front surface with a curved rear surface for predictable light divergence. Offers excellent homogeneity and minimal birefringence. Available with broadband anti-reflective (BBAR) coatings to maximize transmission efficiency.

Advantages Over Alternatives

Outperforms plastic lenses in thermal stability and scratch resistance. Superior wavefront distortion control compared to molded glass alternatives. Lower autofluorescence than phosphor-coated competitors. Maintains optical performance across -40°C to +150°C operating range. Cost-effective alternative to crystalline materials while matching their optical quality.

Benefits Gained

Ensures consistent system performance through precise focal length control; reduces stray light via optimized coatings; enables compact mechanical design integration; lowers total cost of ownership through durability; provides design flexibility with customizable curvature radii; meets RoHS compliance for green manufacturing initiatives.
