Most all Graflex zoom lenses are designed to match an established standard specification and to meet minimum enviromental performance. Further, most all lenses may be customized to a required specification. Please contact factory for the exact standard associated with each lens and available customizations.

Minimum Key Features

  • All metal gears
  • Superb transmittance
  • Excellent boresight retention
  • Very good thermal stability (Optically and mechanically)

Standard Electrical, Control, and Feedback

Iris: 8-16Vdc @ 30mA, 0.4V to 1.0V (Peak to Peak)
Zoom/Focus: 6-12Vdc @ 60mA
AI PCB: 3.0Vdc @ 21mA
Position: Potentiometers at Zoom & Focus
Iris Control: Auto
Control: Analog

Standard Environmental

  • Operating Temperature: The zoom lens will operate after having been exposed and thermally stabilized to any temperature within the range of -30°C and +70°C
  • Storage/Transit Temperature: The zoom lens will not be damaged after having been exposes and thermally stabilized to any temperature within the range of -40°C and +75°C
  • Shock: The zoom lens will not be damaged while subjected to three shocked of 7.5 g for 11msec saw tooth on each axis, in both directions (18 pulses total)
  • Vibration: The zoom lens will operate and not suffer damage when subjected to axial vibration (not angular) or 0.1gRMS within the frequency range of 10-150 Hz

NOTE

  1. Our approach relative to surviving severe environments is to work with a customer to “overcome” any failures which may occur through the testing phase of a lens; it is the responsibility of the customer to environmental test the lens, Graflex would make changes and recommendations based on any failures. Graflex will not warranty lenses for damage resulting from shock or vibration or any other severe environmental inputs.
  2. Published specifications may or may not apply to a specific lens. Please contact factory for specifications as they apply to a particular lens.
