CoaXPress Frame Grabber

A team at the Institut Langevin, Paris, France, recently developed in vivo full-field optical coherence tomography (FFOCT) and demonstrated its capability to capture images in real-time of the central human cornea, resolving features such as nerves, cells, and nuclei without touching the eye. This experimental technology leverages an Adimec CoaXPress camera linked with a BitFlow (Woburn, MA) Cyton-CXP4 CoaXPress frame grabber to acquire high-resolution images directly without beam scanning artifacts, at a frame rate of 275 frames/s (0.6 billion pixels/s). Custom programs written in Labview 2014 and Thorlabs SpectralRadar SDK were used for FFOCT and SDOCT image acquisition and display, peak detection and motor control. Illumination is provided by an NIR 850 nm light-emitting diode (LED) source with light collected by an aspheric condenser lens.

Confocal Microscope

Dragonfly 600 from Oxford Instruments Andor (Belfast, UK) introduces three new features as part of a new total internal reflection fluorescence (TIRF) modality: Borealis TIRF (B-TIRF), a high-power laser engine, and a uniquely designed 3D Super-Resolution module which retains parfocality across all imaging modes. These technical innovations, combined with innovative software, extend Dragonfly’s capabilities to handle single molecule localization microscopy, delivering results with nanometre precision. This new flagship product also maintains the benefits that Dragonfly is known for: it is 10 times faster than point scanner confocals, it images very deep into thick organisms, and it allows users to image live specimens for days without phototoxicity or photobleaching.

Line Scan Imaging System

Chromasens (Konstanz, Germany) has launched a machine vision system that detects cosmetic defects on silicon wafers invisible to the human eye, such as sub-pixel sized scratches, cracks, and stains. The Chromasens wafer inspection system consists of Chromasens allPIXA evo 15k CxP4 mono cameras, Myutron XLS05 lenses, an XCL4 LED controller, and Corona II lighting with coaxial light modules for dark field and bright field illumination. The allPIXA evo 15k CxP4 mono camera is equipped with a trilinear CMOS line scan sensor delivering maximum line length of 15,360 pixels (15K), meaning images captured will have far higher accuracy compared to standard area scan cameras. Leveraging the CoaXPress (CXP) interface enables the camera to achieve full resolution of 15K at line rates up to 68.4 kHz. The allPIXA evo 15k CxP4 camera can trigger up to four different flash controller channels synchronized to its line acquisition using a multi-channel LED flash.

1Digital Pixel Readout IC

Senseeker Engineering (Santa Barbara, CA) announced the availability of the Calcium RP0033, an advanced digital pixel readout IC (DPROIC) with > 120 dB dynamic range and a frame rate of up to 700 frames per second. The 20 μm p-on-n pixel and 640 x 512 format is an industry standard that allows the Calcium RP0033 chip to be used with existing detector and optics technology. The Calcium RP0033 has dual-gain modes with programmable well capacities of over 40 Me- and 400 Me-, each with low read noise of 50 and 330 electrons at 80 K, respectively. The chip is controlled through Senseeker’s SenSPI® interface for easy communications and fast bring-up. It can operate in both integrate-then-read and integrate-while-read modes and has programmable windows to observe and track targets at thousands of frames per second.

GigE Vision Camera

The Mikrotron (Unterschleißheim, Germany) EoSens GE 1.3 megapixel CMOS camera features photo-sensitivity of 2500 ISO/ASA (monochrome) combined with global shutter to enable high-speed image acquisition in very low light conditions without the installation of complex, expensive illumination systems. Its GigE Vision “plug and play” interface lowers the cost of connectivity by eliminating the need for a frame grabber, while achieving speeds up to 80 frames per second (fps) at full 1280 × 1024 pixel resolution, or up to 6140 fps at 60 × 60 pixels. The EoSens® GE measures a mere 63 × 63 × 46 mm, and its features include fixed pattern noise correction, and binning.

1.4 to 3W DC-DC Converters

TDK Corporation (National City, CA) recently introduced the high-voltage output CHVM series of DCDC converters. The series consists of twenty parts, with positive or negative polarity output voltages of 180, 300, 350, 470, 1,000, 1,500 and 2,000V. The maximum output ripple and noise level is just 150mV and typical measurements are between 5 and 50mV. The output voltage can be adjusted over a 0.5 to 100 percent range an external voltage or resistor or inhibited using the remote on/off function. The input voltage is 11 to 13V for the 1.4W and 1.5W models, 10.8 to 16.5V for the 2W and 10.8 to 13.2V for those rated 2.5W or higher. The compact converters are available in three case sizes. The CHVM1R5 (1.4W and 1.5W) measures 44 × 16 × 30mm (WxLxH), the CHVM2 and CHVM2R6 (2W and 2.6W) 110 × 12 × 19.75mm and the CHVM2R5, CHVM2R7 and CHVM3 (2.5W, 2.7W and 3W) 80 × 12 × 19.75mm.

2D and 3D Measurement System

Exact Metrology: A Division of In-Place Machining Company (Cincinnati, OH) presents Planar from InspecVison. This 2D inspection machine allows manufacturers to verify product quality by performing 2D inspection, CAD comparisons, and reverse engineering in seconds. Existing parts can be reverse engineered quickly, creating dxf or dwg CAD files. The software allows the user to edit and clean the data such as standardization of hole sizes and clean edges and eliminates the need for hand measurement and CAD programming. Physical parts or even paper, acetate or electronic image files can be reverse engineered to create CAD files. Reverse engineering processes can also be carried out in 3D using optional 3D modules. For full 3D capability, users simply add Opti-Scan 3D, while the SurfScan module extends Planar to 2.5D. Opti-Scan 3D is a non-contact white light scanning system that uses a high speed, high resolution camera and an LED DLP projector to scan the surfaces of an object. Patterns of light are beamed from the projector onto the part, recorded by the camera and used to create a 3D point cloud of the scanned surface.
