Cylindrical Lens – Circular Plano Convex (CCPX)
Circular cross-section cylindrical lenses
- Line imaging Focal Length: f = R/(n-1)
- n: refractive index
- R: radius curvature
These plano-concave cylindrical lenses are edged as circular shapes so they can easily be combined with other elements in an optical system. Lenses are supplied uncoated. Anti-reflection coatings are available. Please contact the Lambda’s sales teams for more coating information.
