camera is thereby optimally suited for tasks such as electro-luminescence (EL) quality control in the photovoltaic industry. Monitoring the production of solar cells, it reliably detects and identifi es defects such as micro cracks, shunts, and disconnected fi ngers. The intelligent NIR camera also meets all requirements for night- time use. Even at a distance, image capture is effective. The cost-effi cient and highly
fl exible VC solutions do not require cooling systems, since they include all image processing electronics and are able to operate without any additional PC systems. The intelligent cameras independently run functions such as motion detection and license plate recognition. Optional robust housings provide protection for outdoor applications. Measuring just 110 x 50 x 35mm, the units can be integrated even in small spaces. The absence of moving parts makes the systems, which weigh only 400g, an ideal choice for mobile applications. Just like all intelligent cameras from Vision Components, the VC4467/NIR processes several images in parallel and transmits

expanded its selection of Techspec
MgF2 coated achromatic
lenses. Consisting of two optical components cemented together to form an achromatic doublet, these high-performance lenses include fast achromatic lenses and micro achromats. The versatile lenses are computer- optimised to correct for on-axis spherical and chromatic aberrations and offer a wide range of optical solutions for polychromatic illumination and imaging needs. Techspec micro achromats are available in diameters ranging
from 1mm to 5mm in focal lengths from 1.5mm to 20mm. These lenses are available with a single layer MgF2
coating or a
broadband multi-layer coating for the visible spectrum. Micro achromatic lenses are ideal for space constrained imaging applications such as borescopes and medical imaging. Achromatic doublets are much better than simple lenses for multi-colour imaging as the two elements composing the doublet lens are paired together for their ability to correct the colour separation inherent in glass. This is an excellent, cost-effective measure to eliminate chromatic aberrations, making them the ideal choice for a variety of optical applications.

the data in real-time. Equipped with a 1GHz processor from Texas Instruments, it has a computing power of 8,000MIPS. The 2/3-inch CCD sensor has a 1,280 x 1,024 pixel resolution and provides a maximum frame rate of 14fps (28fps in binning mode).
Standard camera models are equipped with 4MB Flash EPROM and 64MB SDRAM for program and image storage, which can be optionally extended by a 128MB SD card. Users can easily adapt the cameras to specifi c requirements by means of the programming languages C and C++. Software libraries for many applications such as motion detection and face recognition are available.

VGA microscope camera Aven has introduced a VGA colour digital camera
that can mount on any microscope. It feeds a high-defi nition signal to the VGA input connection on a monitor, eliminating PC compatibility issues
