Chameleon XS for RealSense cameras AutoVimation has expanded its Chameleon XS enclosure series for the Intel RealSense depth camera family, adding an enclosure for the D455 camera. Te 500g aluminium enclosure provides reliable IP66/67 ingress protection, allowing the depth cameras to be employed in unmanned aerial vehicles, outdoor vision applications and challenging industrial environments. Te outer dimensions are 150 x 64 x


34mm. Te enclosure ensures shade-free images thanks to the special arrangement of the windows, made of anti-reflective BK7 glass. To compensate for thermal expansion and vibrations, cameras are fitted to the housing openings with special seals instead of being glued. Under normal conditions, cooling is not required because the camera is connected with a solid aluminium adapter and a double-layer thermal film for heat coupling with the enclosure. A cable gland with an extra-large sealing


inlay enables tool-free entry of standard cables with USB-C plugs. www.autovimation.com

BitBox starter kit BitFlow now offers a starter kit version of its BitBox device, providing designers with a means to control up to 36 strobes, solenoids, actuators and other accessories in high-density I/O applications. BitBox is also able to acquire data input from equipment ranging from photodetectors to triggers. Te BitBox kit (IOB-ISO-C144-Kit) has 36


inputs and 36 outputs in a compact, DIN-rail mounted form factor that supports TTL, LVDS, open collector, opto-isolated and 24V signalling. All transmitters and receivers are in the BitBox


on the DIN rail, in close proximity to other equipment. Tis configuration isolates noisy, high-voltage signals generated by a PC, keeping those signals away from the system where they could cause data drops, video problems, malfunctions and random network errors. A 15- wire cable runs between the BitBox and frame grabber; maximum cable length is 10m. BitBox contains 12-pin connector blocks


that can be added or removed, but will still lock securely. Blocks are grouped by signal type and have snap-in connectors. www.bitflow.com

EviXscan 3D scanner Evatronix has launched the EviXscan 3D precision scanner. Te scanner is an optical measuring device operating with a blue LED light source. It is equipped with two fast 8.9-megapixel cameras, and is able to measure at 6µm accuracy and 3µm repeatability. Te scans record 1,200 points per square millimetre, with a single scan collecting data from a volume of 120 x 60 x 45mm. Scan acquisition time is in the order of


several hundred milliseconds, thanks to the combination of high-speed cameras and the DLP light projection system. Te scanner is ideal for measuring elements


Telecentric lenses Optotune and Opto Engineering have released eight telecentric lenses. Tese offer a magnification range from 0.24x to 3.5x, and are suitable for the 2/3-inch camera sensor format. Each lens features an Optotune focus tunable


lens embedded into the Opto Engineering lens design to enable focus changes in milliseconds. Tis design offers a fully-integrated solution for industrial vision systems – industrial microscopy and industrial inspection. Te telecentric lenses offer fast and reliable


focusing, enhanced depth-of-field and high image quality, all in a robust and compact form factor. Tey also offer camera orientation independence, low distortion, high image resolution, repeatable focus and no vignetting. www.optotune.com; www.opto-e.com

Micro-LED PL inspection Hamamatsu Photonics has developed a system for high-speed inspection of micro- LEDs on wafers. It can detect abnormalities in the LED’s external appearance, intensity and wavelength of light emission. Te system uses a photoluminescence


measurement technique to characterise LEDs by analysing luminescence images. Te Miny PL system is based on Hamamatsu image processing technology and a newly-developed imaging module. It gives fast pass/fail decisions, which helps increase product yield and R&D efficiency of micro-LEDs. www.hamamatsu.com
