TOA / Tamron 13FG28IR-SQ 1/3-Inch IR Wide-Angle Mono-Focal Lens (2.8mm) Official Optoelectronic Data Sheet & Camera Integration Framework
The TOA / Tamron 13FG28IR-SQ is a professional, high-aperture wide-angle mono-focal (fixed) lens specifically engineered for 1/3-inch and 1/4-inch optical format image sensors on CS-mount security and industrial box cameras. It utilizes special advanced glass composites and anti-reflective coatings to achieve precise infrared (IR) correction. This technology aligns visible and near-infrared light spectrums to the exact same focal plane, completely neutralizing night-time focus blur. Featuring an ultra-bright F1.2 maximum aperture and automated DC Auto Iris circuitry, it delivers an expansive 93.2° horizontal field of view—making it the definitive standard for wide-area indoor tracking, warehouse floors, and parking deck entrance surveillance across Pakistan.
The core optical housing matches precision industrial manufacturing tolerances, but SKYRS provisions and delivers the 13FG28IR-SQ lens platform in specialized hardware configuration profiles for infrastructure projects in Pakistan:
13FG28IR-SQ-STD (Standalone Wide Assembly): The standard industrial IR-corrected 2.8mm wide lens equipped with a factory 4-pin square direct-drive connection layout, perfectly matched for clean indoor corporate box enclosures.
13FG28IR-SQ-ENV (Harsh Environment Profile): Outfitted with specialized dust-sealing gaskets and high-vibration locking mechanical screws supplied by SKYRS. This configuration is engineered to preserve wide-angle optical stability when box cameras are deployed in harsh, dusty, or high-vibration industrial sectors across Pakistan.
Confirm that the targeting camera body utilizes a native CS-mount physical socket interface. If adapting to an older C-mount camera body, a 5mm spacer adapter ring must be inserted first.
Ensure the camera power supply is disconnected before connecting or disconnecting the motorized DC Auto Iris terminal block.
Mount Threading: Remove the rear protective cap from the 13FG28IR-SQ and the camera sensor dust shield. Thread the lens clockwise into the camera CS-mount socket carefully until it is completely flush. Do not use tools to overtighten.
Iris Cable Insertion: Connect the attached 4-pin square auto-iris plug firmly into the designated DC IRIS control slot located on the side panel or backplane of the box camera.
Target Alignment: Turn on the camera system and stream the image matrix to a high-definition service monitor. Loosen the manual focus thumbscrew lock mechanism on the side of the lens housing.
Precision Wide Focus Lock: Because wide-angle 2.8mm lenses capture massive spatial fields, precision calibration prevents edge blurring. Force the camera iris wide open (either by placing a neutral density filter over the front glass or adjusting the camera’s shutter speed settings to simulate low light). Turn the manual focus ring until both the central target and the outer boundaries are entirely sharp, then tighten the thumbscrew firmly to lock the focus in place.
Because the 13FG28IR-SQ relies on passive, high-fidelity optical glass combined with an analog direct-drive iris loop, configuration is finalized inside the host camera’s digital signal processing (DSP) or web controller dashboard.
Lens Drive Selection: Inside the camera system menus, toggle the lens configuration type from “Manual/Electronic Shutter” over to DC Iris to give exposure control to the lens motor loop.
Day and Night Shifting Setup: Because the 13FG28IR-SQ features native broad-spectrum infrared correction, the physical focal point remains identical under daylight (visible spectrum) and nighttime IR illumination. You can safely configure your camera’s mechanical IR-Cut filter to switch automatically without needing to program complex software focus-compensation offsets inside your surveillance software platform.
Notice: The TOA / Tamron 13FG28IR-SQ 2.8mm IR Wide-Angle CS-Mount Lens along with all project-specific environmental stabilization kits are available and supported exclusively through SKYRS within Pakistan.
SKYRS provides specialized security architecture designs, certified hardware validation matching, official factory-backed warranties, and dedicated localized deployment engineering assistance across all metropolitan and industrial markets.
