2.2 Mounting
DALSA recommends that you allow the heat generated by the camera to move away
from the camera. One way to do this is by mounting the camera correctly, as shown:

2.3 Optical Interface
Illumination
The amount and wavelengths of light required to capture useful images depend on the
particular application. Factors include the nature, speed, and spectral characteristics of
objects being imaged, exposure times, light source characteristics, environmental and
acquisition system specifics, and more.
DALSA’s Web site, http://mv.dalsa.com/, provides an introduction to this potentially
complicated issue. See “Radiometry and Photo Responsivity” and "Sensitivities in
Photometric Units" in the CCD Technology Primer found under the Application Notes
and Technology Primers section of the Knowledge Center
(www.dalsa.com/mv/knowledge).
It is often more important to consider exposure than illumination. The total amount of
energy (which is related to the total number of photons reaching the sensor) is more
important than the rate at which it arrives. For example, 5
μ
J/cm
2
can be achieved by
exposing 5mW/cm
2
for 1ms just the same as exposing an intensity of 5W/cm
2
for 1
μ
s.
Light Sources
Keep these guidelines in mind when setting up your light source:
