3.0-9mm F/1.2 IR Mega-Pixel P-Iris Lens

The DF010Q03 lens is an HD Vari-Focal Board-mount lens with IR Cut Filter and Stepper Motor Iris.

Demand for compact, integrated cameras is on the rise in the mega-pixel security camera market due to thier installation efficiency and cost advantages. Tamron brought high-definition monitoring to the mega-pixel security camera market in 2008 with the Model DF010, a 3.0-9mm F/1.2 vari-focal lens for integrated camera, that supports both mega-pixel resolutions and infrared.

In addition, the spread of mini-dome cameras and development of image sensors with higher pixel counts has led to a strong demand for higher definition in monitoring images. Existing lenses could not fine-tune the iris to match the environment, so image quality degradation due to diffraction at smaller aperture in bright areas was common. Tamron has addressed this issue with Model DF010Q03, a vari-focal lens with P-iris technology incorporating a bipolar drive stepper motor for fine-tuning the iris. This enhancement produces high-definition, high-contrast monitoring images in a broader range of camera installation environments.

→ Stepper motor design allows the precise control of the iris setting - There is often a drastic drop in image quality with ordinary lenses due to diffraction phenomenon caused by small apertures. Normally, a galvanometer is used to control the iris of the lens but precise adjustments of the aperture to a desired position were not possible. By using a stepper motor to control the iris, this lens is capable of adjusting the aperture to a position that does not cause diffraction, enabling an appropriate exposure level by utilizing the camera shutter speed.*The result is the ability to record high quality, high contrast images, even in bright outdoor areas. This fine-tune control allows the user to acquire excellent image quality while at the same time achieve good depth of field at most installations.
→ While maintaining resolution above a mega-pixel, the lens delivers a standard range of 3.0-9mm, and F/1.2 brightness. Tamron's proprietary optical design achieves high resolution and high contrast not only in the center, but also at the image corners.
→ Compact design is ready for installation on popular 3-inch mini-dome cameras.
→ An infrared switching mechanism enables 24-hour surveillance, providing clear image quality even at night and near infrared lighting conditions, achieving true 24-hour surveillance.
→ Further improvement in corner resolution is realized over earlier model lenses with more than a mega-pixel in resolution.
→ Attention is paid to diverse CMOS sensor size in the image circle design.
→ Gear rings on the control ring enable remote control of focus and zoom.
→ The lens is designed as an environmentally sensitive product.

*Connecting the lens to a camera that does not support the P-Iris technology may cause malfunction. The lens cannot be connected to cameras that use DC auto iris or video auto iris lenses.
