Tamron announces new shutterless thermal camera module

Tamron Co., Ltd., a manufacturer of optics for diverse applications, has announced the development of a thermal camera module. Stable thermal images In general, a thermal camera module needs to periodically acquire reference data by actuating a mechanical shutter approximately every 2-3 minutes to achieve accurate temperature and stable thermal images. However, when the shutter closes some noise is generated by the shutter and the video will momentarily stop; and furthermore, there is a concern for the mechanical shutter's durability. Now Tamron has developed a "Shutterless Thermal Camera Module" by adopting an amorphous silicon thermal sensor that has excellent temperature reproducibility during temperature changes. Product features Since thermal camera modules can measure temperature and capture image in complete darkness, it enables "Observation" of patients and provide nursing care without disturbing sleep, "Human Detection" without requiring any illumination for security applications, and "Abnormal Temperature Detection" for equipment monitoring, and such applications. Since it is shutterless, it is possible to realise "Observation", "Human Detection", and "Abnormal Temperature Detection" without any shutter noise or stoppage in video.

Tamron’s M13VG2713IR 3MP vari-focal lens supports high resolution throughout visual light and near-IR spectrum

Tamron Co., Ltd., an integrated optics manufacturer in the security/surveillance equipment industry, announces the release of a 3-mega-pixel 1/2.7” 2.7-13mm F/1.4 vari-focal lens (Model: M13VG2713IR) that supports high resolution throughout the visual and the near-IR spectrum. Imagers are migrating toward higher resolution as high-quality images are required for security applications; high-end mega-pixel cameras are increasingly put to night-time surveillance use. Addressing the growing need in the market, Tamron developed an industry-leading high-resolution vari-focal lens that supports ultra-high resolution compatible with 3-mega-pixels throughout the visual light and the near-IR spectrum. The new lens has the following features: Distinguished optical performance Leading technologies such as aspherical lens and extraordinary LD (Low Dispersion) lens are employed together with state-of-the-art optical design to achieve high-fidelity imaging compatible with 3-mega-pixel cameras, exceeding full HD1080P resolution. The lens boasts the fastest F-number; F/1.4, which effectively assures mega-pixel image quality even in low lighting conditions. Mega-pixel imaging sustainable under IR lighting The imaging quality of conventional lenses is often compromised under a near-IR light compared with that of a visual light. Image-quality degradation in the “night-time mode” devalues the advantage of mega-pixel cameras. The new lens maintains high-quality 3-mega-pixel imaging throughout the visual and near-IR spectrum, without quality degradation when a camera is switched to “night-mode”. All lens components are designed with the highest precision and producedusing the most advanced manufacturing technology Wide-utility focal length and wide-angle horizontal FOV angle Mega-pixel image-quality is assured over the most widely-utilised focal-length range of 2.7 – 13mm. The focal length of 2.7mm at the wide-angle (FOV angle of 125.1°) is especially useful to obtain the view of an entire room from a corner point. Reduction of colour blur by elimination of chromatic aberration A new optical design eliminates chromatic aberration to the limit, resulting in images without annoying colour blur. Incoming light reflection on the lens surface is thoroughly suppressed by means of state-of-the-art lens design to prevent its incursion into output images. Employing multi-coating technology also assures flare-free and ghost-free imaging. Highest-precision and highest-quality lens construction All lens components are designed with the highest precision and produced using the most advanced manufacturing technology. In-house manufacturing know-hows are extensively employed to eliminate image degradation such as image shifts and unbalanced blurs in order to maximise optical performance. Improved lens integration Obtrusion of the lens element at the lens mount surface is eliminated to improve lens compatibility with general cameras.

Tamron launches new 5-Megapixel compact fixed focal lens for machine vision use

Tamron, develops distinguished high-resolution fixed-focal lenses that address customers' critical requirements in machine vision Tamron, an integrated optics manufacturer and provider of security/surveillance equipment industry, announces the market launch of a series of fixed-focal lenses for machine vision use that support full 5-mega-pixel resolution for 1/1.2" imagers in compact bodies: Model: M112FM12/M112FM16/M112FM25. Compact lens size Mega-pixel cameras used for machine-vision applications including production equipment, substrate mounting equipment, various test equipment, and various engineering machines migrate toward larger-size imagers and higher resolution. A variety of lenses are available in the market to fit such applications. However, a camera-and-lens combination needs to be optimised for the individual installation condition. Some specific production equipment, substrate inspection equipment, and industrial-use printers mandate lenses that can be installed in a limited space, and ensure high resolution and high contrast imaging in a close-shooting distance. Tamron's machine-vision mega-pixel lens portfolio currently offers lenses for 1.1" imagers (4 models in M111FM series), 1/1.8" imagers (6 models in M118FM series), and 2/3" imagers (7 models in M23FM series, 3 models in 23FM series). With the addition of new compact lenses for 1/1.2" imagers (M112FM series), the portfolio offers the widest selection of high-resolution lenses that address customers' particular needs. Mega-pixel cameras used for machine-vision applications migrate toward larger-size imagers and higher resolution Tamron, as an integrated lens manufacturer, develops distinguished high-resolution fixed-focal lenses that address customers' critical requirements in machine vision, particularly for high optical performance that assures high-fidelity over the whole image, and advanced user utility. Key features: 1. Unrivalled high contrast and high resolution in the industry. The new models are compatible with both 5.86μm pixel-pitch 1/1.2" imagers and 3.45μm pixel-pitch 2/3" imagers, and assure an equivalent resolution of full 5 mega-pixels, an industry-leading resolution and contrast in φ29mm machine-vision lenses. Tamron's proprietary optical design offers equal first-class performance in all different focal lengths of the models. 2. Advanced coating technology and state-of-the-art optical design Tamron's state-of-the-art optics and advanced coating technologies assure distinguished optical performance, particularly in contrast and resolution, and superb optical transmissivity for crisp and clear images. 3. High-quality imaging in a close-shooting distance The new lenses assure high-quality imaging in frequently-used close-shooting distances. 4. Rigid inspection on quality Critical performance in resolution is thoroughly examined from the centre to the periphery of images, assuring high-contrast and high-resolution, devoid of unbalanced blurring, throughout the entire lens view. 5. Improved maneuverability and user utility Rotational torque is increased to improve maneuverability for focusing and iris adjustment. Lock-screw positions are increased to four instead of the three of the former models, assisting easier installation for users. 6. Cosmetic design of rugged look A metal barrel is employed to improve durability and robustness against vibration, giving a cool and rugged exterior look. 7. A commonly-used setscrew is included as a standard accessory A lock-screw used in previous models is replaced with an embedding-type setscrew, making the lens barrel free of a screw-head to enable installation in a compact space.
