Focus Indicator
The Boeckeler IMG 40 focus images objectively for: video microscopy, inpsections, specimen observationsand video print archives. Photo above: video print of an unfocused image of a defect. Photo below: the same image after being focused using the IMG40 focus indicator (note focus display in lower right corners).

Numeric display of focus. The higher the number, the more in focus the video image.
Positionable location of numeric display to one of four corners of the video image.
Selectable window in which focus area may be targeted. Window can be activated at the flip of a switch.
RS-232 interface allows ASCII transmission of focus indicator's numeric display for use with computer printers or for feedback to autofocusing.
Simple component is connected between a video source and monitor. Compatible with NTSC composite and Y/C video equipment.
May be used to complement Boeckeler VIA- video measuring and marking products.
Eliminates subjective focusing of the specimen or manufactured part to aid in accurate and quick inspection and image documentation.
Eliminates eyestrain in video microscopy or any application which requires focusing a video image with the naked eye. Users may refer to a focus number, rather than depend on their own vision to determine image sharpness.
Supplies a means for a repeatable focus. Through RS-232 ASCII transmission of focus numbers, operators may store focus levels for future viewing of the same or similar image.
Easy to use. Anyone can operate the IMG-40 focus indicator with relatively little instruction or installation know-how.
