3. REQUIREMENTS

3.1 General. The individual item requirements shall be as specified in MIL�PRF�19500 and as modified herein.

3.2 Qualification. Devices furnished under this specification shall be products that are manufactured by a

manufacturer authorized by the qualifying activity for listing on the applicable qualified manufacturers list (QML)

before contract award (see 4.2 and 6.3).

3.3 Abbreviations, symbols, and definitions. Abbreviations, symbols, and definitions used herein shall be as

specified in MIL�PRF�19500 and as follows.

IFM

Forward current (subscript M indicates maximum).

Luminous intensity (the subscript V is used to designate a photometric or visual quantity to

differentiate from I used herein for current).

λV

Peak radiometric wavelength of diode light emission.

mcd

Milli-candela; the candela is a unit of luminous intensity defined such that the luminance of a

blackbody radiator at the temperature of solidification of platinum is 60 candelas per square

centimeter.

PFM

Forward power dissipation (the subscript M indicates maximum).

The angle at or off the axis of symmetry of a light source at which luminous intensity is measured.

3.4 Interface and physical dimensions. Interface and physical dimensions shall be as specified in
