🔍 Double Concave Lens (FL 5 cm–15 cm) – Key Features
-
Diverging Optical Lens with 5 cm to 15 cm Focal Length
These double concave lenses are crafted to diverge parallel rays, offering focal lengths from −5 cm through −15 cm, ideal for demonstrations of virtual image formation and optical power studies.
-
High-Quality Polished Optical Glass Construction
Manufactured from optically polished glass with inwardly curved surfaces and carefully ground edges, the lenses ensure clear divergence behaviour, minimal distortion and reliable results in physics lab experiments.
-
Available in Common Diameters for Versatile Setup
Offered in diameters such as 38 mm and 50 mm with focal lengths of 5 cm, 10 cm and 15 cm, these lenses suit a variety of optical bench applications, student experiments and demonstration rigs.
-
Ideal for Educational Use in Refraction and Diverging Lens Studies
This lens type is widely used in schools and labs to illustrate the principles of diverging lenses, negative focal lengths, virtual images, spreading of light beams and basic lens formula applications.
