What do you need?  Perhaps we can help.

Transmissometers, Reflectometers, and Densitometers
Because of the wide range of customers' requirements for this equipment, we have found it necessary to provide "Semi-Customized" instruments than can be tailored to include the exact specialized features needed for each application.

To this end, Graham Optical Systems has developed a "Standard Package" system which we have adapted to produce a number of different instruments to perform measurements as widely varied as:

      The Transmittance of Filters and Thin Films at Specific Wavelengths
      The Transmittance of a Moving Web in a High Vacuum Chamber
      The Optical Density in the infrared of Floppy Disk Magnetic Media
      Simultaneous Transmittance, OD and Reflectance of Photomasks
      Determination of Residue Accumulation by Reflectance of Filter Paper

Optical System Design and Prototyping

Graham Optical Systems offers design and prototyping services for a wide variety of optical devices, instruments and systems.  We will take a system from initial concept through design and engineering detail to the actual prototype.  Examples of systems that we have developed or contributed our expertise are

           High Precision Laser Alignment Systems
           Special Illumination Systems for a variety of industrial purposes 
           Microfilm and Microfiche Scanners, Optics and Illumination
           Optics and Opto-mechanics for Machine Vision Microscope Systems
           Zoom Lens for Ultra-short Working Distances

Optical Design and Prototypes

Ray Tracing, evaluation and correction of aberrations, special single elements, achromats, lens assemblies.  We will design, engineer, and procure lenses, mirrors, window, prisms etc. to your specification. 

Opto-Mechanical Design, Fabrication and Assembly

Graham Optical Systems offers many years of experience in the design and fabrication of high precision opto-mechanical devices and systems  Our specialty is to develop very simple, straight-forward solutions to complex problems in fixturing that involve precision location and ultra-fine adjustment for 
R & D and industrial applications.
