ZOOM LENS OPTIONS

Most every zoom lens we build is done so to a specific customer standard. Variations include electronic, control methods, electrical interface, ruggedization, optical, and bracketry/mechanical interface. With a long portfolio of upgrades, customizations are normally applied with no NRE expense.

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.

BCD Align Device:

The Graflex BCD (Boresight Compensation Device) is a mechanical device that greatly improves the inherent boresight retention of most any zoom lens.

DIS-III Controller:

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.

CFE Lens Enclosures:

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.

ZHS-II Heat System:

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.

Mechanical Interface

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.

Gear Motors:

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.

Electrical/Electronic:

 In most lenses, we offer closed and open-loop systems, customer specified connectors, and encoders.

Ruggedization:

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).
