product focus: peripherals Peripheral vision
Greg Blackman rounds up the latest releases in peripheral components for imaging systems, including lenses and cabling
Among the latest releases in the area of peripheral imaging components are specialist lenses and lighting products from Opto Engineering, available from Alrad Imaging. Opto Engineering designs and manufactures optical systems for imaging, metrology, sensors, projection and lasers. The range of lenses available includes UV bi-telecentic lenses, pericentric lenses, catadioptic lenses, hole inspection lenses, micro polyview optics, F-Theta lenses, telecentric kits and zero distortion macro lenses. Also available are LED pattern and spot illuminators, coaxial illuminators, ring LED illuminators, and back light LED illuminators.

Andor Technology’s Shamrock spectrograph wide-aperture slit provides a flexible and modular approach to microspectroscopy. Only one detection setup with a single camera is required to image samples while allowing spectral information collection through the same optical path from a microscope.
This modular range performs
well with Andor’s fast and sensitive Newton and iXon+ EMCCD cameras, allowing weak Raman or photoluminescence signal collection, down to single photon sensitivity. The Andor solution offers the
benefits of an all-in-one imaging and spectroscopy setup, including C-mount interfacing to all major microscopes, kinematic mounting of a wide range of accessories and
configurations with dedicated Thorlabs cage systems interfaces.

Edmund Optics has introduced its Techspec mid-wave IR achromatic lenses, for applications in MWIR thermal imaging, FTIR, spectroscopy, and for use with tuneable QCL lasers. These high performance lenses are ideal components for use by designers and researchers working in the 3-5µm spectral region. The new lenses provide a small
focused spot with more energy for higher resolution images or greater signal detection. This feature allows designers in industrial, medical, scientific and defence applications to use the full dynamic range and quantum efficiency in their mid- wave sensors.
Edmund Optics’ versatile
new doublets feature precision germanium and silicon lenses, which are expertly air-spaced and aligned within a sturdy anodised aluminium barrel. The lenses are colour-corrected and coated for maximum energy throughput over their full spectral range of 3-5µm. The lenses are available in four 30mm diameter versions with 40mm, 50mm, 60mm and 75mm focal lengths.

The vDisplay HDMI-Pro IP Engine from Pleora Technologies is a compact video receiver that lowers the size, cost, and power consumption of real- time viewing stations in industrial vision systems. It transfers video
data from a GigE network link directly to a standard HDMI/DVI monitor, eliminating the need for bulky, costly, and unreliable PC workstations at each viewing node. The video receiver is based on fan-less, low-power hardware that delivers video to monitors in real time with high reliability and low, consistent latency.
range. Resolve Optics were tasked to design and manufacture a rugged and lockable F-mount periscope focusing system for the SIR3 camera that incorporated a manual iris adjustment enabling use of any prime lens including modern DSLR lenses that have no manual iris control. A micro switch, activated by the mirror slide, was incorporated into the periscope design, to ensure that the camera cannot be used while the mirror is in the focusing position.

A plug-and-play interface makes set-up fast and easy. The receiver is fully compliant with the GigE Vision standard. It supports a wide variety of pixel formats and auto-adapts the incoming video stream to match the display capabilities of connected monitors. This receiver is offered as an OEM board for direct integration into monitors, or as a small standalone unit.

A ruggedised F-Mount periscope from Resolve Optics has been developed for a high- speed ballistic range camera from Specialised Imaging. The periscope is designed to provide real-time focusing of any prime lens on the camera. Traditionally most range camera
designs have made do with lens focusing systems not designed for the high shock and vibration environment of the ballistic testing
Stemmer Imaging supplies cables and cabling solutions from Components Express Inc (CEI). Where extended cable lengths are required, CEI’s Bitmaxx technology utilises ‘pre-emphasis’ and ‘equalisation’ methodology to more than double the distance of Camera Link cables. This not only extends cable lengths at a fraction of the cost of fibre optic repeaters, but also maintains cable flexibility. CEI is also able to make highly customised cables with overmoulded connectors. Overmoulded connectors normally give better shielding than a metal hood as they are 360° taped with copper before the overmould plastic is applied. Working with 3D CAD drawings (supplied by the customer) of the components that are to be connected, CEI can produce a stereo lithography (3D printing) model for a modest charge. This allows the customer to check that the cable meets the space limitations before the overmoulding tool is made. As the lead cable manufacturer in the Camera Link committee, CEI tests all Camera Link cables with real image data using a
