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 lensesÂ
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.
ÂOptical 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.
ÂLenses 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.
