Products Sensors
Global shutter CMOS sensor E2v has added the 2 Megapixel EV76C570 1,600 x 1,200 pixel device to its Sapphire family of high-sensitivity, global shutter CMOS imaging sensors. The device features an identical CLCC48 package to previous Sapphire sensors with only a minor change in hardware. It retains optical compatibility with the 1.3 Megapixel Sapphire sensor which is already in full production. A 1/1.8-inch optical format is retained thanks to the reduced pixel size of 4.5 x 4.5µm. Customers who have developed vision systems around the Sapphire (EV76560) and/or Ruby (EV76C660 and EV76C661) 1.3 Megapixel sensors are able to implement the new EV76C570 to extend their product portfolio with minimal extra development efforts.
The sensor features both rolling and global shutter configuration with 3000:1 global shutter efficiency; 60fps at full resolution with 120MHz clock; 4x separately configurable regions of interest; a lin/log pixel response mode for high dynamic range image capture; and a 10-bit parallel output which can be compressed to 8 bits using a multi-slope commanding technique.
Applications range from machine vision and
smart cameras, to print or barcode scanning, and also traffic and surveillance applications.

Thermal sensor with I2C Ulis, a manufacturer of infrared imaging sensors, has launched the Pico384E, a 17µm pixel size thermal sensor with I2C, the standard Inter- Integrated Circuit link used in many of today’s electronic devices. I2C makes IR sensors compatible with the large-scale production processes used in visible cameras. By adopting design techniques widely used in consumer electronics, Ulis will make IR technology more accessible to new entrants to the thermal camera market.
Pico384E is suitable for compact IR cameras used in high-end military and professional applications that require high thermal sensitivity. Applications include long-range surveillance, Thermal Weapon Sights (TWS), ground vehicle situation awareness, handheld goggles and IR capability to UAV (Unmanned Aerial Vehicle). The sensor’s power consumption is less than 60mW (analogue output, 50Hz frame rate). With an I2C bus speed, Pico384E operates up to 400kHz. It has a NETD (Noise-Equivalent Temperature Difference) in the range of 40mK, and a thermal time constant under 10ms.

Ideal for industrial inspection Carl Zeiss has released the Axio Zoom.V16 microscope, ideal for industrial inspection. Zoom microscopes are now combining typical benefits of stereomicroscopes such as zoom optics and long working distances with the higher resolutions of light microscopes. In comparable image fields, Axio Zoom.V16 offers a 2.5 times higher resolution than stereomicroscopes. The microscope has a 16x zoom range. Zoom microscopes with high apertures offer decisive benefits when it comes to scanning component parts as well as in quantitative and qualitative materialography. Identifying homogenous component parts is as vital for optimising production processes as it is for quality assurance.

Microscope system Keyence has released its latest microscope system, the VHX-2000. By integrating advanced zoom optics with a CCD camera, 17-inch LCD monitor, light source, controller and analysis/ reporting software, the VHX streamlines testing and improves the speed and efficiency of the inspection process.
With a magnification range from 0.1-5,000x, the VHX Series enables a wide range of microscopic observation from macro-scale stereoscopic imaging to the detailed analysis of an SEM. Many lighting techniques are also supported including bright and dark field, transmitted, polarised, and differential interference observation. Building on top of the VHX platform, the VHX- 2000 incorporates several new features. A colour filter wheel has been added to allow users the option of choosing a specific wavelength (red, green or blue) of light for their samples. A super resolution mode combines the blue filter with Keyence’s pixel shift technology, capturing images with 25 per cent better resolution. To improve the operation and ease-of-use, the VHX-2000 can be equipped with a motorised XY stage along with motorised Z-axis lens control. Users can adjust movement in all three axes by using an included control pad. When combined
with the company’s Double’R lens/magnification recognition function, the VHX-2000 can automatically provide the ideal movement speed for the XY stage and enables one-push automatic focus and calibration. The image stitching function can now be completed with just the push of a button, and at much higher speeds, to produce up to a 20,000 x 20,000 pixel image that expands the viewing area by up to 200 times. Automated measurement functions simplify the most difficult of measurement tasks and help to remove variation between different users.

Fast imaging of large measuring surfaces with high enlargements allows for statistical analysis of structures: details such as pores can be enlarged to a great extent, then analysed, digitally imaged and documented.

Illumination
LED light engine Schneider Kreuznach has developed a state-of- the-art light engine. The Fiber Light Ultra LED Engine 6 has been designed to couple light efficiently into a fibre bundle. Outstanding 1,200 lm luminous flux for 6mm diameter active fibres (NA 0.54) deliver enough light with an excellent Illumination distribution for challenging tasks. This makes the LED engine the perfect choice for
32 Imaging and Machine Vision Europe • June/July 2012
medical applications, where small diameter light guides are commonly used.
The Ultra LED Engine 6 is designed around a high brightness LED source. An appropriate ventilation fan for cooling the LEDs is an essential part of the unit. It is compact and provides 30,000 hours life time, which keeps maintenance to a minimum.
