Durango is the Universal Interferometry Software™ for data acquisition, analysis, evaluation, exchange, import/export and simulation. 

Durango uses only published algorithms and gives you full access to raw measurement data and intermediate results. 

Durango offers power, speed, flexibility, hardware independence, ease of use and value in one comprehensive package.

The images at the left are examples of the many graphics which Durango can produce.  Examples of 3D plots are shown below.

      General Features offered by Durango 
                  Fast 32-bit code running under Windows XP
                  Intuitive interface makes keyboard almost unnecessary. 
                  Responsive, anticipates user requests while responding promptly to user input.
                  Online, context-sensitive help. 
                  Knowledgeable and responsive technical support. 
                  Affordable, permanent license includes 1st year support and upgrades 

      Data Acquisition and Control

        User can specify number of frames and phase shifts
        Automatic or manual calibration of phase shifter 
        Live Image window makes separate monitor unnecessary 
        Remote triggering and/or automatic data saving 
        Import images (.raw, .bmp, .jpg, .png) or data files (MetroPro, Opticode). 

Data Analysis

        Published algorithms, no voodoo 
        Robust, correctly computes and unwraps even noisy phase data 
        Select from numerous phase algorithms, before or after data acquisition 
        Re-purpose any phase algorithm as a spatial-carrier static algorithm 
        Editable pixel masks for computation and analysis 
        User control of pixel rejection criteria 
        User control of Unit Circle for aperture scaling and registration 
        Fitting algorithms handle circular and non-circular apertures 
        Remove tilt, power, coma, astigmatism, cylinder, reference, residual 
        Unlimited Zernike or monomial fitting terms 
        Unlimited fiducials with graphic and spreadsheet editing
        FFT-based diffraction analysis for PSF, Encircled/Ensquared energy, MTF 
        OPD Arithmetic for analyzing multiple surface or wavefront maps. 
        Synthetic data support, with optional phase and intensity noise 
        Save ALL data, or just the OPD map. 

 Presentation

    Supports all screen resolutions 
        Unlimited windows may be opened, closed, moved, resized, minimized 
        Bitmap display of OPD, frames, phase, modulation, intensity and slope 
        Dynamically review frames, tilt phase maps, rotate 3D surfaces 
        Histogram display of phase step, OPD, modulation, intensity and slope 
        Printable reports from fully customizable HTML templates
        Export to CodeV, Excel, ASCII, .xml, .raw, .bmp, .jpg.

Durango and Universal Interferometry Software are Trademarks of Diffraction International.
Visit their website and download a FREE Demonstration copy of Durango Software. 

Then send us some of your samples.  We will evaluate them with one of our interferometers and Durango Software, put the files on a CD and send it to you so that you can have a look at the great job that GRAHAM Interferometers and Durango can do for you!
