Thank you for visiting the Alternative Vision website. In these
pages, we are pleased to present a large and varied selection of
unique optical and electronic imaging products and services. Our
product lines start with lenses. From
Optec, we supply
lenses covering wavelengths from ultraviolet through infrared
including over twenty models of NIR lenses for use in the
900-2300nm band with InGaAs cameras, a dozen lenses especially
designed to work with 3CCD cameras in close conjugate
applications and an extensive selection of collimating,
objective, and relay lenses for coupling x-ray image intensifier
output phosphor images to CCD cameras. Behind the lenses, we
supply prisms for separating the incoming illumination into
several bands. The prisms are available with 2 to 5 output
channels and can cover the band from 300 to 3000 nm. The
splitting can be neutral or spectrally selective including the
common RGB scheme.
Optec provides
these prisms as glass alone, with lens mounts and filter and
sensor supports or as complete, precisely-aligned cemented
assemblies incorporating image sensors from ¼ inch to 24 x 26
mm. High-temperature versions suitable for autoclaving are
available. For those who do not want to build their own cameras,
we supply multispectral cameras with up to five channels using
Optec prisms from
Quest Innovations. We
also offer stock and custom dichroic filters and filter
assemblies from
Thin Film Physics.
Tattile offers
a complete line of cameras and vision processors for industrial
applications. GigE connected cameras offer frame rates from 15
to 200 fps for any application as well as a line of Ethernet or
Camera Link connected CCD smart cameras. For MWIR and LWIR
imaging, we offer lenses from
Wavelength Technology.
We also provide sensors. For high-quality color imaging, we have
the
Foveon X3 Direct
Image Sensor incorporating the breakthrough layered-photodiode
color separation technology that preserves full resolution in
color images without the use of color filters that can cause
aliasing. To support designs of cameras for the Foveon F13
sensor, we supply the DevCam series from
FoMOS Cameras
as part of our AVF-35 and AVF-35 camera Design Kits. For the
most unique imaging applications, we supply custom CMOS sensors
incorporating the SiLM and ACT techno0logies from
Lumiense
for both area and line imaging in visible, NIR and LWIR. Through
its cooperation with
HanVision,
Lumiense can offer custom sensor development services at very
reasonable prices. For fully custom optical designs, we
offer the services of the
Polaris Research Group
(PRG). Among its extensive capabilities, PRG includes the design
of custom embedded microscope optics including objectives,
collimators, multi-wavelength LED illµminators, and imaging
couplers for transmission, polarization, interference,
fluorescence and a host of special microscope techniques. PRG
also offers imaging system design services, image processing
algorithm development, design of light sensor subassemblies
including interface electronics and analysis of difficult
optical problems leading to recommendations for high-performance
solutions. Finally, we offer a series of unique and
hard-to-find optical components and assemblies under our
Avicon brand
including x-cube prisms, axicon lenses, laser collimators and
germanium singlets. We are always looking for new and
different products to distribute. Please let us know if you see
one we ought to carry.
