High Performance At 3 Mega-Pixel /
Full HD Mega-Pixel Resolution In The Near Infrared Spectrum
Near infrared radiation refracts differently from visible light, causing blurring in an image captured in the near infrared spectrum.
Tamron IR Mega-Pixel Lenses utilize cutting-edge optical design technology and advanced low dispersion glass to converge the
focal points of visible light and near infrared radiation, providing 3 mega-pixel image quality 24-hours a day.
■Comparison of a Visible Light Lens and an IR Lens
Delivering Exceptional Image Quality And Outstanding Video Surveillance Day Or
Night Using State-Of-The-Art Aberration Correction Up To The Near Infrared Spectrum
With conventional lenses, image blurring occurs in surveillance
camera video footage shot under near infrared illumination
because the optimum focus point changes as a result of the
difference between the refractive indices of near infrared and
visible light, which also affects their wavelengths (see figure
at right). The Tamron IR Mega-Pixel Lens Series features the
latest optical design formulas and low dispersion glass
technologies that resolve this focus point discrepancy. This
eliminates image degradation, even in black and white mode,
and delivers 3 mega-pixel quality image for 24-hours surveillance
at any time of day regardless of the lighting conditions.

Versatile Zoom Range From 2.8 To 8mm
F/1.2 Fast Aperture Allows Surveillance Under Extreme
Low-Light Conditions With Mega-pixel Resolution
With a maximum angle of view of 100.1°, this lens can image an entire
room when installed in the corner.
Designed For Compatibility With Current Camera Technology
Internal components in the vicinity of the imager are designed to
minimize protrusion from the lens mount face for full compatibility with
nearly all surveillance cameras on the market.
Superb Picture Quality
Designed to minimize color aberrations, ghost and flare for top picture
quality.
