TAMRON ANNOUNCES TELEPHOTO NEAR INFRARED LENS FOR DAY/NIGHT CAMERAS

New 10-40mm F/1.4 Available for Both 1/3-inch CS-Mount and 1/2-inch C-Mount CCD Cameras

January 31, Commack, NY —Tamron's new addition to the IR lens line-up, 10-40mm F/1.4 IR Aspherical Vari-Focal is available for two imager sizes: 1/3-inch and 1/2-inch. This new lens, along with the simultaneous announcement of a 3.0-8mm F/1.0 IR Aspherical Vari-Focal covering the standard range, makes Tamron’s IR line-up the most extensive in the industry.

While virtually all camera manufacturers are marketing Day/Night cameras today, and the need for 24-hour surveillance is overwhelming, the selection of IR-corrected lenses offered by manufacturers has been slim to none. Tamron’s line covers a variety of focal ranges to meet market needs, including the only Mono-Focal IR lenses on the market. With the addition of the 10-40mm, Tamron now has three Vari-Focal solutions for 1/3-inch CCDs that cover wide angle, standard and telephoto ranges, and four Mono-Focals from 2.8mm to 8mm. Each is available in both manual iris and DC auto iris versions.

Tamron developed this new lens specifically to address the need for a telephoto range IR lens that is required as outdoor applications using IR illuminator systems become increasingly popular. This range is also particularly useful for indoor applications where close-up identification of people is necessary.

Like the 2.8-11mm IR already available, and the new 3.0-8mm F/1.0 IR announced at this time, the 10-40mm F/1.4 IR Vari-Focal uses state-of-the-art optical design and LD glass technology to solve the out-of-focus range between visible and near-IR light. Using Tamron’s special Multi-Coating also improves transmittance in the near-IR range and effectively eliminates flare and ghosting. High quality images are achieved by using Aspherical lens elements.

Even while covering the telephoto range up to 40mm, it provides installers with a fast maximum aperture of F/1.4 and a minimum aperture of F/360 to ensure optimum imaging performance even in broad disparities of lighting, predominantly outdoors, throughout a 24-hour period. The Tamron 10-40mm will give an excellent image quality no matter what time of day or lighting situation.

In looking at the total market, Tamron determined a 1/2-inch version was needed since many Day/Night camera manufacturers have stepped up to a 1/2-inch CCD sensor to maximize the performance of the minimum lux. Tamron’s new IR lens now allows users of these cameras to fully utilize and appreciate the day/night features.

Both models of the 10-40mm lens feature locking mechanisms built into each ring (focus, iris and zoom) and provide a built-in Slip Mount mechanism for precision installations. The designers have even considered environmental impact by making a lens that is environmentally friendly in design: glass with no lead content was selected and lead-free solder was used to manufacture the lens.
