The APL-1050 from Laser 2000 is a variable-focal-length singlet fluidic
lens utilizing proprietary design, formulation and packaging. It is a
new component for the optics market and is affordable, durable,
high-quality, and high-precision.
A lens core of the APL-1050 includes a lens fluid, an AR-coated and
polished glass substrate, and a transparent elastomeric membrane. The
highly-inert and non-compressed optical fluid is hermetically sealed
inside the lens core. The lens core is encased in an aluminum housing
that includes an actuation mechanism and angular markings. A portion of
the lens core extends outside of the housing and has a ring-shaped grip
for rotary manual actuation. Rotation of the grip results in
compression of the lens core and a deformation of the membrane. The
deformation of the membrane caused by non-compressed liquid is
spherical and this results in a change in focal length of the lens.
