| 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 illµmination 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.
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. For the most unique applications, we
supply custom CMOS sensors from
Lµmiense
for both area and line imaging in visible, NIR and LWIR. Through
its cooperation with
HanVision,
Lµmiense 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. Line scanners come from CMOS Sensor.
These compact scanners save space in machine vision systems
while providing very high scan speeds and convenient CameraLink
interfaces. 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 consulting
in development and marketing of industrial and scientific
imaging equipment through
Pacific Photonics.
We are always looking for new and different products to
distribute. Please let us know if you see one we ought to carry.
