Our
products combine Hardware and Software
While our instruments can be used with an optional
eyepiece, their true power emerges from the combination
of precise optics and powerful image analysis software.
Until a few years ago, optical instruments like telescopes and autocollimators included an eyepiece for visual observation. Image analysis software existed, but was expensive, complicated to use, and difficult to install. As a result, many of us spent long hours in darkened rooms, peering through eyepieces. However, the evolution of computers and digital image capture devices has changed the playing field, and powerful image capture and analysis tools are no longer prohibitively expensive.
PixelScope™ software has been designed to meet the specific needs of the optical engineer. The software is intuitive and easy to use. (Want proof? Download a demo version, and decide for yourself!)
You may also view the software manuals online in our downloads section without installing the software.
With PixelScope™ you can:
View images in real time. Pan and zoom down to the individual pixel level.
Load images from camera, disk or clipboard. Save all or part of image to clipboard or disk as image or array of intensity values.
Apply powerful image analysis “tools” to selected areas of the image.
PixelScope™ can capture live images from these sources:
Firewire Video cameras supplied by Wells Research and ThorLabs. These cameras have excellent price performance ratio. While not as low-noise as cooled CCD cameras, their performance is well matched to the needs of optical measurement and testing.
The tools are designed to accomplish these tasks:
View the image formed by
an optical system
An optical engineer can tell a great deal about the
performance of an optical system just by looking at
the image as the system moves through focus. PixelScope™
is designed to make this easy to do. You may pan and
zoom down to the individual pixel level. The "cross
section" tool permits you to view a cross section
of any selected area of the image. The histogram tool
permits measurement of intensity at any selected area
of the image.
Measure the location of
features within the image
PixelScope™
permits measurement of the location of abitrary features
within an image with sub-micron accuracy. Results
may be viewed as a numerical value, or plotted vs.
time. This extremely powerful capability is used internally
by many of PixelScope's™
tools.
Measure image quality
MTF is now the accepted way of measuring and reporting
image quality. PixelScope OpticStudio™ supports
MTF measurement from 3 types of target (pinhole, narrow
line, and edge.) PixelScope OpticStudio™ also
permits measurement of contrast from 3-bar targets,
removing the problem of operator subjectivity. For
the skeptical, 3 bar contrast measurements provide
an independent demonstration that the powerful, but
perhaps less intuitive, MTF measurements are indeed
correct. Finally, PixelScope OpticStudio™ supports
measurement of veiling glare, (also known as lens
flare.)
Measure lens parameters
PixelScope™
measures lens focal length automaticallly with a few
mouse clicks. PixelScope™
also makes it easy to measure image plane location,
depth-of-field, field curvature, etc. By changing
narrow band filters, it is possible to measure chromatic
characteristics such as axial and lateral color.
Evaluate lens aberations
The optical engineer often thinks of a lens in terms
of the classical 7 lens abberations: (Spherical abberation,
Coma, Astigmatism, Field Curvatrue, Distortion, Axial
color, lateral color) PixlelScope permits the optical
engineer to visual identify of all these abberations.
Document your results
It is easy to export both pictures and numerical values
from PixelScope™. Many tools
(such as the cross section tool and MTF tool) allow
exporting data to the clipboard in a form that can
be pasteed directly into Excel.
