17 Apr 2012 Cylindrical lens has at least one surface that is formed like a portion of a cylinder.These patented gradient-index cylindrical microlenses with Luneburg type refractive index distribution are drawn from a highly polished gradient-index fiber preform. A simple tuning of the drawing process produces diffraction-limited microlenses in the shape of fibers or rods with precise diameters and unsurpassed surface quality. When illuminated sideways, these fibers act as perfect cylindrical lenses with 0.5 NA. The fused silica cladding and the gradient-index core of these lenses withstand very high temperatures (transition temperature is ≈1100°C).
Styles:
Plano-concave lens have a negative focal length and are used for image reduction or to spread light.Plano-convex lens have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.
Applications:
●Bar Code Scanning ● Projiection Optics Systems ●Laser Measurement Systems ● Holographyr |
