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.
