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 900-1700nm 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. We also offer stock and custom dichroic filters
and filter assemblies from
Thin Film Physics.
Tattile offers a complete line of
vision solutions 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
readers. 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
from Lumiense
for both area and line imaging in visible, NIR and LWIR. Through
its cooperation with
HanVision,
Lumiense can offer custom development services at very
reasonable prices. For area cameras, we offer
Micro USA,
which produces very-wide dynamic-range cameras in both
monochrome and three-chip color. For multispectral cameras with
up to five channels, we supply products and services from
Quest Innovations.
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. For owners or manufacturers of equipment that is
currently or nearly obsolete, we offer legacy services from
Micro USA,
experts is reverse engineering old avionics, microwave,
electro-optical and communications equipment to support repairs
or design of modern replacements. Finally, we offer a series of
unique and hard-to-find optical components and assemblies from
Pacific Photonics 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. |
