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:

Camera-to-object distance (OD): distance from face of camera to object

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

Object size

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:

Magnification (M) = Object size / CCD size

Focal length (FL) = OD / (M + 2 + 1/M)

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.
