Electrical Specifications

Notes:

(1)

Distance from the front of the lens to reflective surface.

(2)

Measured using Eastman Kodak gray card. The white side of the card is used as a 90 % diffuse reflective surface. Reference Eastman Kodak

catalog #E152 7795.

(3)

All parameters are tested using pulse techniques.
