TECH FOCUS POSITIONING EQUIPMENT


The diSPIM has been tested


successfully on cells cultured on cover slips, cells embedded on collagen gels, zebrafish embryos, and other samples. www.asiimaging.com


Positioning patients To accurately position a patient for scanning, radiologists and other medical practitioners require a highly visible (green or red) laser line or cross in a robust, compact housing. ProPhotonix worked with a


healthcare equipment provider to produce a compact 635nm laser module, thousands of which are in operation. Wavelength patient- positioning systems typically use a laser mounted alongside the imaging instruments, showing where images will be taken and allowing the instruments and patient to align to get the best image. Usually a red (635nm) laser line or cross is used, to give a high level of visibility. In some cases green is used due to the human eye’s sensitivity to green and the need for clarity when projected onto the skin of patients. Patient positioning


applications require excellent bore sighting (alignment of the laser beam with the body of the laser housing) and clean lines without breaks, bright spots or other irregularities. ProPhotonix can offer bore-sighting to <25° and robust lasers with extremely clean lines. The custom laser product underwent significant product testing including ESD, vibrational, shock and thermal testing. Each laser module is also thoroughly tested before it is shipped to the customer. www.prophotonix.com


Siskiyou goes large Siskiyou has expanded its IXF series of monolithic flexure optical mounts to include larger models that can accommodate 3 inch (75mm) and 4 inch (101mm) diameter optics. These mounts utilise a unique configuration in which all parts, including springs, are fabricated from a one piece of metal. This improves heat

transfer through the mount over the traditional kinematic construction, and delivers excellent long-term pointing stability, even in the presence of temperature changes. These two axis mounts


feature adjustment over an angular range of 5°, and are supplied with fine pitched (100 TPI) screws which offer


an adjustment resolution of 1.5arcsec. The IXF mounts are compatible with Siskiyou’s patented optics clip. This adhesive-free mechanism is designed to retain high flatness components (e.g., optics with a flatness of λ/10 or better) without noticeably degrading wavefront performance. www.siskiyou.com


Introducing our new range of High QE Photomultipliers


Our new range of end window photomultipliers is available with blue-green sensitive high Quantum Efficiency (QE) bialkali photocathode and high stability, SbCs dynodes of linear focused design for good linearity and timing.


These photomultipliers are available in 30 mm, 51 mm and 78 mm diameter versions and they are ideal to be used in applications requiring high statistical signal to noise ratio of the photocathode.
