ZOOM LENS OPTIONS
Optical (MTF) Testing:
Via our state of the art MTF system, Graflex is also able to provide complete lens analysis services including MTF (1D & 2D), LTF, EFL, flange FL, BFL, focus deviation, boresight deviation & retention, astigmatism, and depth of focus. Lens capability through approximately 2030mm and 8″ free aperture.
The Graflex DIS-III controller includes a PCB and GUI and may be applied to most any zoom lens no matter the manufacturer. The system not only allows for serial interface via RS-232, RS-422, and RS-485, but also Ethernet. The DIS-III is also VISCA and PELCO compatible.
The Graflex family of CFE Carbon Fiber Enclosures are not really an option but a product within itself. At a fraction of the density of aluminum, carbon fiber is a clear choice where extreme strength and low weight are desired characteristics. Although we manufacture standard sizes, the size/shape possibilities are endless.
The ZHS-II applies concentrated heat direct to the zoom lens, or any other device, via small heater pads. The ZHS-II system includes heater elements, thermostat, and is fully programable via a separate controller.
Beyond a wide range of standards, Graflex will build custom interface brackets to meet any requirement. From the simple addition of alignment pins to multi-axis tilt and lock brackets we can, and have, done it all.
Outside of the standard 12Vdc in most lenses, we also offer 6Vdc and 9Vdc motors, non-standard gearbox ratios, wide (low to high) temperature grease, and encoders.
In most lenses, we offer closed and open-loop systems, customer specified connectors, and encoders.
We possess the knowledge and experience of modifying zoom lenses for the most severe environments. Our projects include modifications to survive shock up to 75 g’s, temperatures as low as- 45° celcius, and severe functional vibration (and the removal of resultant video distortion).
