Product Description
Plano Convex Lens Definition
Plano Convex Lens (PCX) focus parallel rays of light into a single point which is the lens focal length.It is suitable for accumulation and focal length light and is ideal for emitter, detector and laser applications.
Plano-convex lenses, convex on one side and flat on the other, have a positive focal length and are commonly used for related applications such as reducing the beam, reducing the focal length, or enlarging an image. In order to reduce spherical aberration, when a plano convex lens is used for collimating beam focusing, the beam should be incident on the surface of the lens. When used for point source collimation, the beam is incident on a plane.
A plano convex lens focuses light into a single point. It is often used for aiming and focusing monochromatic light sources. When in use, the convex surface faces the incident light. Ruike Optics offers plano convex lenses coated with anti-reflection film.
Germanium, Silicon or Zinc Selenide substrates are suitable for infrared applications, while fused quartz bk7 CaF2 are suitable for ultraviolet applications.
How to calculate Focal length of PCX?
F=R/(n-1)
F is the focal length of the lens
n is the refractive index of the lens
R is the curvature radius of the lens
