The LENEX lens is a high-class optical component designed for professional video surveillance systems. It is a varifocal product with a range from 2.8 to 12 mm, which allows for flexible adjustment of the field of view to the specific requirements of the monitored area – from a wide view to details. A key advantage of this model is full infrared (IR) correction. The lens uses an advanced system of lenses that compensate for chromatic aberration, ensuring that the image remains perfectly sharp after the camera switches to night mode and the IR illuminator is activated.
The product is fully adapted to work with modern megapixel cameras up to 2 MP (Full HD) resolution. Thanks to the high F1.4 aperture, the lens performs excellently in difficult lighting conditions, providing a bright and clear image. The use of a DC auto-iris makes the device react automatically to changes in light intensity, protecting the camera sensor from overexposure and ensuring optimal contrast. A solid construction and standard CS mount make it compatible with most professional compact cameras available on the market. By choosing this lens, you gain certainty of stable system operation 24 hours a day, regardless of the prevailing lighting conditions, which is crucial for security and effective identification of events.

Specification
Dedicated sensor
1/2.7" - The lens has been optimized to work with sensors of this size, ensuring full frame coverage without vignetting.
Dedicated resolution
2 MP (Full HD 1080p) - resolution describing the number of elementary points of the sensor. The higher the number, the greater the detail of the image.
Lens mount
CS - standard thread used in industrial cameras, enabling stable and precise mounting of the optics.
Focal length
2.8 ... 12 mm - adjustable distance between the focal point and the main point of the system; a smaller value means a wider angle of view, a larger one means zoom.
Iris
DC (Direct Current) - automatic iris controlled by DC from the camera, dynamically adjusting the amount of light falling on the sensor.
Aperture (F)
1.4 - a low aperture value means a large relative aperture, which allows for capturing a clear image even in very poor lighting conditions.
Zoom
Manual - zoom adjustment is done manually using a ring on the lens housing, usually locked with a screw.
Field of view for 1/2.7 inch
87° ... 25° - wide range of field of view allowing for general observation or detailed view of a selected fragment of the scene.
Infrared (IR) correction
Yes - special lens design eliminates the focus plane shift when changing lighting from visible to infrared (day/night operation).
Aberration compensation
The lens uses a system of lenses to compensate for chromatic aberration specifically for the infrared band, which prevents image blurring.
Focus adjustment
Manual (Focus) - precise focus setting using a dedicated ring with a locking mechanism.
Material
High-quality optical glass with anti-reflective coatings and a durable housing ensuring parameter stability over time.
Manufacturer / Brand
LENEX - a recognized supplier of optics for CCTV industrial television systems.
Warranty
2 years (24 months) - full manufacturer's warranty provided by an authorized service center.
