Lens
selection is very critical for megapixel cameras. This month our tech
bit of the month feature frequently asked questions regarding lens
selection.
What
size lens do I use?
The
megapixel cameras have a ½ inch sensor, therefore use at least ½ inch
or 2/3 inch lens as a minimum(CCD cameras typically use ½ inch or
1/3 inch).
What type of lens?
"Megapixel" lenses should be used. Yes, there is a class
of lenses called Megapixel.
We only suggest using lenses from well known companies, such as,
Computar, Fujinon, Tamron or Pentax lens. These are all high quality and
great performance lenses.
Varifocal verses Fixed focal length
The varifocal lens is typically preferred over fixed focal length
lens. We have only seen a few varifocal megapixel lenses, but the fixed
focal length lens always outperforms the varifocal.
Do the cameras accept C or CS mount lens?
The cameras will accept either C or CS mount lens. Many CS mount
lens will require a 5mm spacer.
Auto-iris verses non Auto-Iris
Our most popular cameras are manual Iris cameras. All Arecont
cameras feature a CMOS sensor rather than a CCD sensor that is used in
most Analog cameras. These CMOS sensors do not exhibit the bright light
blooming problem that is seen in CCD sensors. CCD sensors require
auto-iris for minimizing the blooming.
Auto-iris is typically used for applications where depth of field is
very important. For example, if the camera is used for viewing a parking
lot, and the camera is positioned near eye level, then auto Iris is
important, since during the bright sunny day, the camera iris is closed
down, therefore producing a deep depth of field. Then as the sun sets,
the iris opens up to allow more light to hit the sensor. If the camera
is mounted on a high pole over looking a parking lot, then the auto-iris
feature is not necessary, since the depth of field is not a major issue.
Auto-iris is not available on the AV3130 since both day and night
lighting conditions are split between the two sensors and lens.
In General, the non auto-iris lens are far superior lens in quality to
auto-iris lens.
What type of lens should be used for the AV3130?
You may have noticed that he AV3130 lenses mounting holes are very
close to each other. Therefore only fixed focal length lenses from
Fujinon, Computar, Tamron or Pentax will work on the AV3130. These fixed
focal length lenses range from 3.6mm to 50mm. The higher quality
varifocal lenses diameter is too large to fit. The Outside Diameter of
the lens must be no larger than 1.5 inch. All fixed focal length
lenses(except Computar 5mm) from our price guide will fit the AV3130.
What is the proper aperture setting for a megapixel cameras?
The optimal position for megapixel lens is f2.8 to f4.0

I-CUBE carries a wide
variety of lenses. Due to the number of lenses available, we can
only list some of the most common. Please contact I-CUBE if you
have a specific lens requirement or question.

General
lens selector criteria
NOTE: these are basic
guidelines and are not appropriate for exact lens selection. For a
specific lens recommendation, contact I-CUBE
Needed measurements:
Do not confuse working
distance with Camera-to-object distance. Working distance is
measured from the front of the lens to the object being viewed
If you are measuring the
width of your object, then use the horizontal CCD specifications
-
CCD size (HxV):
-
1/3"
CCD = 4.8mm x 3.6mm
-
1/2"
CCD = 6.4mm x 4.8mm
-
2/3"
CCD = 8.8mm x 6.6mm
-
1"
CCD = 12.8mm x 9.6mm
-
1"
= 25.4mm
Formulas:
Example:
Camera-to-object distance =
12" = 304.8mm
Selected camera: 1/2"
CCD
Object size: 3" =
76.2mm
Preferred orientation:
horizontal
M = 76.2 / 6.4mm = 11.9
FL = 304.8 / (11.9+2+ (1 /
11.9)) = 304.8 / 13.98 = 21.8mm
Lens choice: 25mm
Video Inspection Optics
Lenses for Viewing Objects
2" or Smaller
Navitar offers the Zoom
6000, TenX Zoom and 12X Zoom video microscope systems which will
outperform most CCTV lenses for close-up, high magnification
applications. Typically, CCTV lenses were designed to work from 3' to
infinity, but Navitar's Zoom 6000, TenX and 12X lenses are ideal for
applications that require a much shorter working distance. These
rugged lenses have built-in locking set screws and can handle the
vibration of a typical machine application. And because they are
specifically designed for high magnification, they have a higher
contrast level and less edge distortion that conventional CCTV lenses.
Lenses for Viewing Objects
2" or Larger
Navitar offers the Zoom 7000
macro lenses featuring the same parfocal zoom capabilities offered by
the Zoom 6000, TenX Zoom, and 12X Zoom series while allowing close-up
image capture without extension tubes or close-up lenses.

IR-CAM 55X is a radiometric thermalimaging system which
can be handheld and has features that are praise worthy. Superb
image quality, accurate temperature measurement, digital image
storage and analysis/reporting software package are some of the
main features. This device is mostly used in boiling and
refracting analysis. The placing of the controls is constructed
so that they can be at your finger tips. It has an easy to use
format that can make any user feel at home while operating the
device. The controls are so well placed that your fingers will
easily be able to be placed and will not have to move from one
control to another.
Features:
This device has got excellent features. It is because of the
