Terminology
Image Sizes
There are several types of imaging sensors with different image sizes for CCTV cameras, the
aspect ratio of CCTV camera is normally 4:3 (H:V). The size of camera’s imaging sensor affects
the angle of view, with the smaller sensors creating narrower angles of view when used with the
same lens. The format of the lens, however is not related to the angle of view, it merely needs to
project an image which will cover the sensor, i.e., the same format of the camera or large. This
also means that 1/3” cameras can use the entire range of lenses from 1/3” to 1”, for example, a 1/3”
12mm lens gives the same angle of view as a 2/3” 12mm lens does. The latter combination also
provides increased resolution and picture quality as only the center part of the lens is being used,
where the optics can be ground more accurately.
WD
Focal Length
Rays from infinite distance objects are condensed internally in the lens at a common point on
the optical axis. The point at which the image sensor of the CCTV camera is positioned, is
called a focal point. By virtue of design, lenses have 2 principal points, a primary principal
point & a secondary principal point, the distance between the secondary principal point and
the focal point (image sensor) determines the focal length of the lens.
12
Terminology
The focal length of a lens is measured in mm and directly relates to the angle of view that will
be achieved. Short focal length provides wide angle of view and long focal length becomes
telephoto, with narrow angle of view.
Terminology
Angle of View
The angle formed by the 2 lines from the secondary principal point to the edges or corners of image
sensor is called the angle of view. Theoretically, the focal length of a lens is fixed regardless of the
image size of the CCTV camera. Conversely, the angle of view varies according to the change of
image size. For a certain image size, the angle of view will increase when the focal length
becomes shorter. The focal lengths in the catalog are nominal and the angles of view calculated
by the formula referring to the focal length are approximate.

Aperture (F No.)
Aperture is an index for the amount of light that passes through a lens. The value of the aperture
is represented by the F No., the smaller the F number, the greater the amount of light, and the
brighter the image generated by the lens. The F No. is inversely proportional to the entrance
pupil diameter of the lens and directly proportional to the focal length. Its formula is as follows:
F No. = f / D (f: focal length, D = Entrance pupil diameter)
Auto Iris and Manual Iris
Terminology
There are three types of operation for lens iris, that is, (1) DC drive auto iris; (2) Video drive auto
iris and, (3) Manual iris. For DC drive type, the iris is controlled by the circuit inside the camera;
for Video drive type, the iris is equipped with an amplifier inside and is operated by the video
signal and DC power supply from the camera; for Manual type, the iris is manually adjusted over
the adjusting ring on the lens.
M.O.D.
The M.O.D. (minimum object distance) is the closest distance from the vertex of the front lens to
the nearest object at which an image can be focused.
13
Terminology
Depth of Field
The depth of field (DOF) refers to the area within the field of view which is in focus. A large
depth of field means that a large percentage of the field of view is in focus. A small depth of field
means only a small section of the field of view is in focus. The depth of field is of following
properties:
1) The larger the F No. is, the wider the depth of field becomes.
2) The shorter the focal length is, the wider the depth of field becomes.
3) The longer the distance to the object is, the wider the depth of field becomes.

CS and C Mount
The CS-mount lens has the flange back distance of 12.5mm. The C-mount lens has the flange
distance of 17.5mm. The CS mount lens is only applicable to the CS mount camera, but the C
mount lens is fit for both C mount and CS mount cameras as long as a 5mm adapter ring is used
to match the CS mount camera.

Flange Back Distance, Back Focal Length, Mechanical Back Focal Length
Flange back distance is the distance between the lens flange and the sensor focal plane.
Back focal length is the distance between the vertex of the rear lens element and the sensor
focal plane.
Mechanical Back Focal Length is the distance between the surface of the lens frame and the
sensor focal plane.
Non IR Lens vs IR Lens
Day & Night cameras are normally used in near-infrared (NIR) or infrared (IR) at night. If we use
a Non IR lens with a day & night camera, the image will be out of focus (shifting) at night. Our
special optical designs with broad band co-focusing technology based on special glass material
minimize light dispersion. As a result, refocusing is not required when the camera is used under
NIR or IR. The special design makes the lens to deliver perfect focusing either under visible light
or under IR illumination circumstances.

Terminology
Megapixel
CCD and CMOS image sensors use a series of pixels arranged on a 2 dimensional grid. These
pixels convert an optical image to an electronic signal. The number of pixels in an image usually
defines the resolution, more pixels means higher resolution. A megapixel is defined as one
million pixels, while camera with a megapixel sensor is called a megapixel camera.
Megapixel lens for megapixel camera
To achieve the full resolution of a megapixel camera, it is essential to use a high quality
megapixel lens. Overall image quality is greatly affected by the quality of the optical image shot
onto the image sensor. Megapixel lenses provide high contrast, brightness and sharpness
across the entire image plane. Non-megapixel lenses will not fully display the resolution of
megapixel sensor, especially in the corner area of the image.
