Statement of Requirements New Optical Microscope

Mechanical and Aerospace Engineering Naval Postgraduate School

1.0 Background/Introduction:

The MAE department at the Naval Postgraduate School (NPS) owns an inverted metallurgical optical microscope. The microscope is a Nikon Epiphot 200, which is still functional. The microscope, however, is old and finding replacement parts is increasingly difficult. This is especially problematic as Nikon no longer manufactures optical microscopes. To compliment and eventually replace the Nikon optical microscope, we seek a new inverted and/or metallurgical optical microscope. The new microscope will be used in the same way as the Nikon, primarily by students, but also by staff and faculty for their classwork and research. The microscope should be one that can image metallic, ceramic, polymeric, and composite samples. The microscope should also allow for imaging of mineralogical samples. It should come with software capable of both hardware control and imaging analysis.

LED.

- The microscope must come with an adjustable binocular eyepiece to accommodate multiple users.

- It must come with a built-in power source.

- The microscope should come with a reflector cube and analyzer for the polarization mode.

- It must also come with a reflector cube, objective lenses, and prism for DIC mode.

2 1 EA

Camera for the microscope:

- A digital camera that can connect by USB

3.0 to an included computer (item 3) is required.

- The camera should be a high-resolution camera with selectable resolution, minimum 1920 x 1080 (1080p).

- It must also come with enough RAM to run microscope software (item #4).

4 1 EA

Software:

- Microscope should come with image analysis software that can control the microscope; process images with standard correction schemes like contrast control;

and allow for image analysis.

- Software should be capable of grain size analysis, porosity, and phases.
