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, lenses especially
designed to work with prism-based 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 6 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 including high-temperature versions suitable for
autoclaving. 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,
who offer GigE connected cameras, CameraLink cameras with frame
rates from 15 to 120 fps and fiber connected cameras for secure
long-distance data connection. We also offer stock and custom
dichroic filters and filter assemblies from
Thin Film Physics.
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 camera design kits. For the most unique imaging
applications, we supply custom CMOS sensors incorporating the
SiLM and ACT technologies 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.
