Computar Ax4Z2812xCS-MPIR series lenses

The CBC Group company released the megapixel varifocal lenses Computar of the Ax4Z2812xCS-MPIR series which are supplied with the lenses corrected in the Infrared range in February, 2015 and are compatible to day-night cameras with large-format sensors to 1/2.7 and with a resolution up to 3 megapixels. All lenses day-night of a new series have compact dimensions, universal fastening of CS type and adjustment of focal distance in the range of 2.8-10 mm. At the same time the lineup of Ax4Z2812xCS-MPIR includes optics with manual and automatic iris control, including P-Iris of type.

High resolution capability allows to use the Ax4Z2812xCS-MPIR series lenses Computar with IP cameras which have large-format matrixes with diagonal 1/2.7, 1/3 both 1/4 inches and permission up to 3 megapixels. Selection of lenses in new optics practically excludes emergence of chromatic and geometrical aberrations and also barrels including at the edges of a frame, at projection of a light bunch on a camera detector. Thanks to it, lenses allow to receive day-night the qualitative image on all frame, and their high degree of a svetopropuskaniye improves indicators of the minimum illumination of the camera in the modes day and night.

A series of Computar optics includes lenses with manual — A4Z2812CS-MPIR, and automatic iris control — AG4Z2812FCS-MPIR and AG4Z2812KCS-MPIR which differ with type of management DC Iris and P-Iris, respectively. At the same time lenses with P-Iris technology are day-night the most progressive models as adjustment of their diaphragm is performed by the electric motor managed by specialized software. Thanks to it, it is possible to achieve the maximum tuning sharpness of the size of lens opening for receiving from the camera day-night of the image with an optimal contrast, clearness and depth of field under any conditions of illumination on an object.

Correct work of new products with IP cameras with True Day/Night technology is reached due to installation in lenses of the lenses corrected in the Infrared range. Such lenses do not allow an image defocusing when switching the camera between the day and night modes of video filming. At the same time varifocal lenses save day-night focusing parameters in all range of opening of lens opening and changes of focal distances. It is important to note that along with preserving of high sensitivity of cameras in the modes day-night, the Ax4Z2812xCS-MPIR optics will effectively work at illumination of a zone of video control with IK-searchlights.

Fast and coincidence tuning of a required viewing angle of A4Z2812CS-MPIR, AG4Z2812FCS-MPIR and AG4Z2812KCS-MPIR is performed using the ring set on lenses which allows to regulate focal distance in the range from 2.8 to 10 mm. For the camera with the 1/2.7-inch sensor lenses will provide day-night horizontal viewing angles from 127.6 ° up to 34.3 °, and on format 1/4 matrix' – from 73.7 ° up to 21.3 °. At the same time the minimum distance of focusing of new products makes 0.5 m. For video control on objects of corridor type it is recommended to use the A3Z3112CS-MPIR model as this lens has day-night functionality for increase in depth of field up to optimum level.

As well as other optical devices Computar, lenses of the Ax4Z2812xCS-MPIR series are distinguished by high quality of execution and the affordable price. Their lenses are executed of the optical glass having high degree of a svetopropuskaniye and abrasive stability. Thanks to the compact sizes and small weight, lenses can be established day-night on the cameras placed in thermocasings for video filming in street conditions. Simplicity of construction and strength connection with cameras provide day-night a possibility of operation of new products during long term.
