Tamron : 13VG1040ASIR-SQ
Description
The Tamron 13VG1040ASIRSQ is a 1/3″ IR 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 13VG1040ASIRSQ 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.
Tarnrons High Resolution IR Vari-Focal Lens 13VG1040ASIRSQ incorporates 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 enhances the overall sensitivity of Day & Night cameras, allowing operation in color mode under dimmer lighting conditions.
The 13VG1040ASIR SQ features 1/3″ Angle of View (wide/telephoto) at 27.5° x 20.4°/7.0°x5.2°. 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 todays demand for Image resolution, while maintaining a compact and easy-to-install design.
Tamrons 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.
