What this bin holds
Our biconcave lenses are clear glass optical components. They diverge light beams, making them suitable for optical instrument correction and laser beam expansion.
This pack contains six biconcave lenses, each with a 3 cm (1.18 inch) outer diameter and a -7.5 cm (-2.95 inch) focal length. They are crafted from optical-grade clear glass, offering clarity and environmental durability. The 4 mm (0.16 inch) thickness ensures the double-concave design provides precise beam divergence and a negative focal length.

Who takes it home
These lenses are often found in laboratories, research facilities, and optical projects for laser beam expansion, optical instrument correction, and precision targeting systems. When integrating, adjust the distance and alignment with other optical components, like convex lenses, to achieve the desired beam spread or correction. Clean them with a lens-specific soft cloth.
