The Tamron 13VG2812ASSQ is a 1/3" Mega-pixel vari-focal lens with auto-iris (DC) and connector. Near-infrared radiation refracts differently from visible light, causing blurring in video footage captured in the near-infrared spectrum. The Tamron High Resolution IR Lens Series utilizes cuffing-edge optical design technology and advanced low-dispersion glass to converge the focal points of visible light and near-infrared radiation, providing exceptionally sharp image quality 24-hours a day.
Tarnron's High Resolution IR Vari-Focal Lenses incorporate Aspherical elements and ID (Low-Dispersion) glass to provide a resolution of 650W lines. The resolution at the image corners has been improved by more than 50% over conventional models to provide superb image quality over the entire image field.
The focal point of the near-Infrared spectrum is corrected to match that & visible light to provide exceptional image quality over the entire range of wavelengths from visible light to near-Infrared. The fast aperture of F/1.0 enhances the overall sensitivity of Day & Night cameras, allowing operation In color mode under dimmer lighting conditions than with conventional F/1.2 and F/i .4 lenses.
The 13VG2812AS SQ has an iris range of F/1.6 0 360. With the advance of high-resolution cameras and the rapid digitization of recording systems, there is a growing demand for GCTV camera lenses that can provide high resolution across the entire screen. As a leading manufacturer of integrated optics, Tamron now offers a lineup of high resolution Van-Focal lenses that meet today's demand for Image resolution, while maintaining a compact and easy-to-install design.
Tamron's devotion to image quality is evident in the exceptional image resolution. Our high resolution Van-Focal Lenses provide a resolution of 650 TV lines over the full range of aperture sizes. Multi-coating Is applied to key lens a surfaces to minimize ghosting and flare. The result is consistently sharp contrast and excellent image quality. Each control ring for zoom, focus and iris* can be independently locked to prevent deviation after installation. (*Manual iris only)
Each lens is equipped with a slip-mount mechanism that allows rotational adjustment of the lens after it is mounted on the camera. This allows optimal positioning of the auto-iris actuator and cable during installation. All lens components are produced using advanced, high-precision manufacturing technologies to prevent image defects such as local blur and focus shift.
