Liquid Lenses Market - Global Industry Analysis and Forecast 2024
Liquid
lenses are used to create infinitely variable lenses with the help of
one or more fluids. An infinitely variable lens is created without
the movement of any parts by controlling the surface of the fluid.
Liquid lens can be categorized into two types such as reflective and
transmissive. Such types of liquid lenses are very different from
liquid formed lenses, which are created by placing an epoxy or a drop
of plastic on a surface and then left to harden into the shape of a
lens.
Reflective
liquid lenses are variable mirrors, which are used in reflector
telescopes instead of traditional glass mirrors. When a fluid
container is rotated, the centripetal force creates a reflective
concavity, which is highly suitable for telescopic applications.
Transmissive liquid lenses uses two unmixable fluids, each having
different refractive index. The different refractive index allows the
creation of variable focus lenses with high optical quality of 10
microns. Among the two fluids, one is an electrically conductive
aqueous solution and the other is a non-conducting oil. The two
fluids are stored in a small tube with lucid end caps. One of the
caps and the tube’s interior are coated with hydrophobic material,
which allows the aqueous solution to form a shape of hemispherical
lens on the opposite side of the tube. In order to control the shape
of the lens and decrease water repellency, dc voltage is applied
across its coating and this process is known as electrowetting.

The
module of a liquid lens is an electronically controllable variable
focus system. Liquid lenses makes the use of two iso-density liquids,
water as a conductor and oil as an insulator. The change in the
voltage leads to the variation in the curvature of two liquids, which
changes the focal length of the installed optical lens. The major
advantages and characteristics of liquid lenses are its ruggedness,
better optical quality, lesser power consumption, small in size and
swift response times. In addition, liquid lens ensures the smooth
installation, maintenance and setup by eliminating the requirement of
opening the reader and touching the lens. It has immense application
for reading distances, which changes part to part and has
extraordinary swift response times compared to other auto focus
equipment.
Liquid
lens technology is highly preferred over conventional lens
technology. Liquid lens does not have any movable parts and has an
optimal power consumption level. Unlike the liquid lens, conventional
lens technology requires mechanical adjustments in order to focus or
enlarge the images, being captured. In addition, liquid lens is 85%
smaller in size compared to typical camera lenses and therefore it
finds immense application in mobile and optical devices, where weight
and size savings are extremely vital.
Increasing
application of liquid lenses in cameras, telescopes, mobile and
optical devices is the major factor driving the growth of liquid lens
market, globally. In addition, rising demand for high performance and
energy-efficient lens is a crucial driver for the liquid lens market.
Moreover, the rising popularity of photography and demand for pro-HD
cameras, which are required for extreme sports are also a vital
driving factor influencing the growth of liquid lens market. However,
high cost associated with the manufacturing of liquid lens is set to
inhibit the growth of this market.

North
America is considered to be the largest liquid lens market, globally,
followed by Europe, Asia Pacific, Middle East and Africa, and Latin
America. Increasing application of liquid lens in photography,
videography, scientific, medical, mobile and optical instruments are
the major factors driving the growth of liquid lens market in North
America. Some of the key players in the liquid lens market includes
Cognex Corporation (U.S.), Invenios (U.S.), Varioptic (France),
Optilux (U.S.) and Imagine Optics, Inc. (U.S.) among others.
