Best Plano Concave Lens
Westech Optical makes custom optics.
Plano concave lens. Given their negative focal length and negative spherical aberration plano-concave lenses can be used to balance out aberrations of other lenses in the system. 5 is located in the air. 1964 A plano-concave lens made of glass of refractive index of 1.
A lens with one convex and one concave side is convex-concave or meniscus. Integration with conventional plano-concave contact lens system so that one lens can be removed and replaced by another lens easily. They can be used to diverge a light beam and to increase the focal length of an existing lens or lens assembly.
Plano-concave lenses diverge a collimated beam from a virtual focus and are commonly used in Galilean-type beam expanders. Thus their size allows manipulation on the eye without interfering with placement of the surgical instruments. N-BK7 is an excellent lens material for most visible and NIR applications.
A simple lens has two surfaces. Determine its radius of curvature. Get a Free Quote.
We will rush samples and not at extraordinary prices. N-BK7 Plano-Concave Lenses Our N-BK7 Plano-Concave lenses are available uncoated or coated with a variety of multi-layer antireflection coatings. They can be used in beam expanders and projection systems.
10500 Lens Plano Concave Negative ZnSe - Model. Plano-Concave Lens Definition A lens is made of a refractive or transmissive media like glass plastic or transparent crystal. For the purposes of this tutorial we apply the following equation to describe lens action.
