Points for choosing Camera, Lens, Lighting

     
 

It is critical to consider the required conditions for your application which is key for choosing the correct imaging devices. Common parameters and dimensions are shown. (Refer to Figure 2-1a)

 
   
     
 
Camera Spec Area sensor or Line / B/W or Color

Sensor format / Resolution on sensor side
Size of pixel / Lens mount / Flange back
Parts installed in front of sensor / Spectral response / Shutter speed / Sensitivity …etc

Adapters

Protection Cover Filter / Filter (Rotary polarized, Sharp-cut, Band-pass)

Prism, Mirror etc.
Mechanical

Zoom or Fixed Mag. / Fixed Iris or Adjustable
Motorized Zoom or Focus / Locks for focus and iris

Environment

Temperature, Humidity / Vibration, Shock

Unnecessary Light / Dust, Water

Illumination ● Type of Light Source ・ Wavelength
①Halogen Light Source + Fiber Optics ②LED Light ③Fluorescent Light(Daylight Color)
④Others

●Method
①Direct angle light ②Indirect light ③Back light ④Co-axial light
