The
focal point
is the p oint at w hich the im age of an infin itely d istant object is brou ght to
focu s. The
effective focal length (f
)
is the d istance from the second p rincip al p oint to the
second focal p oint. The
back focal length (BFL)
is the d istan ce from the im age sid e of the
lens su rface to the secon d focal p oint. The
object distance (OD)
is the d istance from the first
p rincip al p oint to the object.

Warning!
Dep en d ing on the m ou nting d esign an d the op erating cond itions the cam era

Mounting Instructions and Recommendations
Prop er cam era m ou nting ensu res that the heat generated by the cam era d issip ates
p rop erly an d that the cam era m aintains a safe tem p eratu re.
1.
The cam era shou ld be bolted tightly to a m ou nting p late m ad e of therm ally
cond u ctive m aterial (e.g. Alu m inu m ).
2.
Keep contact area betw een the cam era’s front su rface an d the m ou nting p late su rface
as large as possible. Do not use ―stand -off‖ style mounting.
3.
Design the cam era m ou nting p late so th at there is enou gh su rface area to d issip ate
heat. An exam p le of a p rop erly m ou nted cam era is illu strat ed on the follow ing p age.
4.
Forced air flow to the fins is the m ost effective w ay to cool the cam era. If forced air
flow is not available, then leave enou gh sp ace arou nd the fins so that heat can easily
d issip ate into the air by natu ral convection.
5.
The m ou nt setu p p lu s the airflow m u st d issip ate 44 Watts or m ore of heat.
6.
Prop er therm al m ou nting of the cam era sh ou ld resu lt in an internal cam era
tem p eratu re < 65 ºC (verify u sing com m an d vt) and a fron t p late tem p eratu re < 50 ºC.
N ote:
To avoid intern al d am age the cam era au tom atically shu ts d ow n w hen the internal
tem p eratu re reaches 75 ºC.
The recommendations assume the following conditions:
The cam era m ou nting p late has at least 5,047 m m sq. con tact su rface (equ al to the fu ll
cam era m ou nting su rface, as show n) and ap p roxim ately 3,000 m m sq. of natu ral
convection su rface.
N o im p ed im ents to the natu ral convection sp ace arou n d the su rface of the m ou nting
p late an d the su rface of the cam era.
An environm ent tem p eratu re of ap p roxim ately 25 ºC.
Good contact betw een the m ou nting p late an d the cam era su rface.
