La description

What are cylindrical lenses?

Cylindrical lens, also called a cylinder, is an optical lens which focuses light on to a line instead of on to a point, as a spherical lens would. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it onto a line parallel to the intersection of the surface of the lens and a plane tangent to it. The lens compresses the image in the direction perpendicular to this line, and leaves it unaltered in the direction parallel to it (in the tangent plane).

These lenses are used to correct the output from diode lasers, to produce a round beam from the diodes elliptical output. They are also applied in optical systems to correct the shape of laser beams, change image aspect ratios, and illuminate in the shape of line source.

 

Materials available for cylindrical lenses 

Choosing from substrates of N-BK7 glass, UV fused silica, or CaF2, all of which are available uncoated or with an anti-reflection coating (AR coating).

 

Production of cylindrical lenses

Cylindrical lens from Phtonchina is among top-level in terms of surface quality, irregularity and dimension tolerance. It also provides the high precision, special shapes and specifications designed by customers.

Photonchina design and manufacture cylindrical lenses(include round versions), plano-convex, plano-concave, acylindrical lenses and cylindrical achromatic doublets. Achromatic cylinder lenses provide additional color correction by minimizing chromatic aberration. Hydrid acylinder lenses are typically used for color correction, in addition to minimizing spherical aberration.

 

Our precision cylindrical lenses are produced to meet the demanding requirements of laser electro-optic applications. They are manufactured from fine annealed optical glass or other materials designated by customers and are polished to tight tolerances to ensure minimum wavefront distortion. Tight surface quality tolerances minimize scatter and unwanted diffraction effects.

 

Optical coating

By virtue of over *0 years of experience in designing and operation of optical coating technique, Photonchina uses its vacuum coating equipment imported from Germany or Japan as well as domestic brand to supply a very wide of coating service for customers worldwide.

 

Broadband visible antireflection coating

Our broadband multilayer antireflection coating markedly improves the transmission efficiency of these lenses by reducing surface reflections over a ******0nm wavelength range. This AR coating performs effectively for multiple visible wavelengths and tunable lasers eliminating the need for several sets of optics.

 

Laser V-coating from Photonchina offers the lowest reflectance at ***4nm for maximum transmission while maintaining high durability and excellent damage resistance. Valuable laser energy is efficiently transmitted through the plano-convex lens rather than lost to surface reflection and scattering. The trade off to its superior performance is the minimal laser line wavelength range.

 

Lenses made by Photonchina have especially been suited for sensitive laser applications, including laser scanning, diode laser beam shaping. Additional applications include focusing light into a thin line for optical metrology or collecting light in spectroscopy systems. They can also be used to expand the output of a laser diode into a symmetrical beam.
