Configuration
Back to Top
|
| ||
| Mounting | |||
| Your choices are... | |||
| Handheld / Pocket | Small, portable inspection magnifiers with reticules for various geometric features such as radii, distance scales, etc. | ||
| Benchtop | Designed to sit on a bench or tabletop. Typically somewhat smaller than floor-mount models. | ||
| Floor Mount | Larger units that are freestanding on the floor; often larger than their benchtop counterparts. | ||
| Other | Other unlisted, specialized, or proprietary type. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Inspection Table Movement | |||
| Your choices are... | |||
| Manual | Stages are moved by hand, typically with some mechanical assistance, such as a micrometer feedscrew. | ||
| Motorized | Table motion is motorized; typically provides precise, consistent movement. | ||
| CNC | Movement is controlled by or can be tied in with computer numerically controlled (CNC) equipment. The result is very precise, programmable motion. | ||
| Other | Other unlisted, specialized, or proprietary inspection table motion control. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Projection / Orientation | |||
| Your choices are... | |||
| Horizontal | Image is projected horizontally. | ||
| Vertical | Image is projected vertically; includes configurations where operator looks "down" at projection; may have a slight angle. There may also be a 90° reflection to create final projection on a vertical screen. Most common in floor-mount type comparators. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Image Projection: | |||
| Your choices are... | |||
| Inverted | Typical for entry or standard-level comparators, the relatively simple optical system provides an image that is inverted vertically (upside-down) and horizontally (left-to-right). Adjustment and inspection require some practice. | ||
| Erect | More advanced optical system renders the image in its natural or "correct" orientation; image appears in the same orientation as the part being measured or evaluated. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Telecentric Optics? | Advanced optic system that maintains projection size at different points of the focus travel; associated with erect image projection. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||

|
| ||
| Screen Size / Field of View: | Diameter of viewing screen; values typically range from 10"-12" for small units to 36"-40" for larger units. Even larger screen sizes are available. For pocket or hand-held comparators, this specification represents the field of view. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Horizontal Measurement Range: | Range of horizontal motion for part inspection; relative part view will depend on factors such as magnification. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Vertical Measurement Range: | Range of vertical motion for part inspection; relative part view will depend on factors such as magnification. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Magnification Range: | Range of part magnification, typically changed by changing comparator lenses. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
| |||
| Resolution: | Smallest unit of distance that can be discriminated by the comparator. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||

|
| ||
| Digital Readouts | Numeric readouts, either on simple displays such as LCDs, or more advanced video displays. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Electronic Angle Measurement | Measurement of angles such as for notches, vees, chamfers, and tool geometry is captured electronically, avoiding manual and visual operator manipulation. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
