THE MIC-1 LASER INTERFEROMETER

is the most versatile optical testing device of its kind on the market today. The MIC-1 was designed with human engineering in mind for a range of users from the amateur to the professional test engineer. Its ruggedness and durability has been proven in over 20 years of service. It delivers repeatable and reliable test results every time. One instrument doing the job of many is what makes the MIC-1 your affordable answer.

The MIC-1 eats vibration! You could use it to test optical components and systems on a picnic table. The design integrity of the MIC-1 with the high speed CCD camera allows testing in a high vibration environment, even in a fully lighted room. It is mountable in any physical orientation for maximum flexibility and freedom of use.

APPLICATIONS

The MIC-1 is a universal testing instrument that can be used to test most optical components or systems, including flat and spherical mirrors, test plates, lenses, prisms, telescopes, Cassegrain systems, on-axis and off-axis paraboloids, ellipsoids, reconnaissance cameras, and more. Its uses are as varied as the optical testing problems that you may have.

The MIC-1 has been used to test micro lenses .01 inches in diameter, 60-inch telescopes, and, we think, everything in between.

FEATURES

• Lightweight and portable, can be moved between work stations without losing instrument alignment
• Can operate in all physical orientations
• Superbly crafted
• Smooth, precise, accurate mechanical controls
• Rapid fringe acquisition
• Interference printouts easily produced
• Quick, uncomplicated laser replacement and realignment
• Will test optics of unlimited size from microlenses on up
• No physical contact with measured surface
• Can test a wide range of focal ratios using economically priced beam divergers.

MIC-1 SYSTEMS

The MIC-1 comes equipped in Standard Projection Mode. Accessories create different modes of operation and can be added at any time. You can switch between systems in just a few minutes.

• Standard Projection Mode - for ground glass/white screen viewing and photography.
• Video System - using CCD camera for displaying fringes on a black and white monitor and recording on video graphic printer.
• Phase Measuring System - computerized phase measuring capability, manipulation and analysis for greater height and spatial resolution.

STANDARD EQUIPMENT

MIC-1 comes complete in Standard Projection Mode with one each of the following: f/5 beam diverger, uncoated (4%) reflectance reference flat, full (94%) reflectance reference flat, and projection lens.

ACCESSORIES

• Beam Divergers:
  f/Nos. 16, 13, 10, 8, 7, and 5 (f/5 included as standard equipment). Other fast focal ratios may be available on request.
   
• Reference Mirrors:
  In addition to the 4% and 94% reflectance included as standard equipment, we offer a 50% partial reflectance reference flat. Mounted in quick change holder.
   
• Micrometer Head (2 inch dia.):
  In place of standard focus lead screw for quantitative measurements. Must be ordered with instrument.
   
• Ghost Reducer:
  (For use in Standard Projection Mode.) Adjustable iris diaphragm/spacial filter, mounts at focal plane of projection lens. Improves contrast when testing with uncoated reference flats and test optics by reducing ghost fringes/reflections.

ACCESSORIES - VIDEO SYSTEM

• CCD Camera:
  For displaying interferograms on a video monitor and/or computer. Especially useful when testing uncoated or low reflectance/transmission optics even in a fully lighted room. With selectable shutter speeds of 1/60 to 1/10,000 of a second, it can be used without vibration isolation table. This small, high precision CCD Camera is readily interchangeable with the standard projection lens allowing user to switch between video and projection modes in a matter of seconds. The camera is fitted with a 2.5-1 magnification zoom lens and a detachable variable transmission filter.
   
• B/W Video Monitor:
  For fringe display. Available in two sizes: 9" and 13".
   
• Video Graphic Printer:
  combines with CCD Camera and monitor to produce interferograms economically on thermal recording paper. The frame grabber enables you to print interferograms in a vibration environment.

ACCESSORY - PHASE MEASURING SYSTEM

• For computerized data acquisition and analysis, we offer Diffraction International's Durango Interferometry Software with their PZT Linear Stage customized for the MIC-1. This fast, 32-bit code program computes and unwraps even noisy phase data without error, allows the user to specify the number of frames and phase angles, and provides automatic or manual calibration of phase shifter.
  
  Data analysis capabilities include:
  
  
  • Selection of numerous phase algorithms
  • Pixel masks and user control of pixel rejection criteria
  • User control of unit circle for aperture scaling and registration
  • Remove tilt, power, coma, astigmatism, cylinder, reference and residual
  • Synthetic data support
  • Unlimited Zernike terms and fiducials with graphic and spreadsheet editing
  • Fully customizable reports
  
  Additional information about Durango can be found at: www.diffraction.com.
   
• Requirements:
  
  The MIC-1 must be equipped with the CCD camera option.
  
  Your desktop or laptop PC must be running Windows 7 or XP and have three open slots and/or USB ports.
  
  Environmental stability is critical when using the Phase Measuring System.
