34 — Frequently Asked Questions & Troubleshooting
When I connect the USB cable from the VariSpec filter’s Electronics Controller
module to my computer, Windows asks me where 'ftdibus.sys' and 'ftser2k.sys’ are.
What can I do? The filter does not seem to be recognized by the Windows operating
system.
Sometimes the Windows operating system’s Plug and Play feature for new devices
does not work entirely seamlessly. If you followed the directions to install the SDK
onto your computer and received no error messages during or after the installation,
those files should be located in: C:\Program Files\Cri\VariSpec\USB. Use the Detect
New Hardware wizard to browse to that location and select the appropriate file. After
the Detect New Hardware wizard is finished, the VariSpec filter should operate
normally as a new USB serial device.
I need a multispectral imaging system, and your VariSpec filter technology looks
ideal. But I don’t want to do any system integration. Do you have a turnkey
solution?
Yes. We also manufacture and sell the Nuance™ Multispectral Imaging System, the
R&D 100 Award-winning Maestro™ In-Vivo Fluorescence Imaging System, and the
Vectra™ microscope slide analysis system. Contact CRi for more information
([e-mail]).
• Nuance systems can be used for a wide variety of brightfield and fluorescence
applications, including FISH and FRET experiments, multicolor
immunohistochemistry, general fluorescence or brightfield microscopy, tissue
microarray investigation, and high-content screening research. The Nuance optics
module is compact and robust, with standard C-mount coupling for easy
integration onto existing microscopes. A tripod socket is supplied for remote-
sensing, forensic, machine vision, or other macroscopic applications. A
workstation computer with Windows-compatible multispectral imaging software
is also included.
• Maestro systems are affordable, breakthrough instruments for fluorescence-based
in-vivo molecular imaging. Using multispectral acquisition and analysis, they
provide dramatically improved sensitivity, multicolor flexibility and quantitative
accuracy for both visible and near-infrared labels. The systems virtually eliminate
contrast-robbing autofluorescence, revealing otherwise invisible targets that
appear bright against a near-black background. This dramatic improvement in the
signal-to-noise ratio can increase sensitivity many fold, allowing much smaller or
fainter targets to be detected. A workstation computer with Windows-compatible
multispectral imaging software is also included.
• Vectra™ is the world's only multispectral fluorescence- and brightfield-capable
microscope slide analysis system. Vectra's pattern recognition-based scanning
rapidly acquires high-resolution multispectral images of samples on microscope
slides. Samples can be cultured cells, cell spreads, tissue sections or tissue
microarrays, stained with standard stains such as H&E or trichrome, or
immunofluorescence and immunohistochemical techniques. CRi's intelligent
scanning approach, based on multispectral imaging, pattern recognition and
machine learning, provides a more quantitative, more efficient and faster
