Digital Microscope Camera

The PAXcam2+ digital microscope camera from MIS, Villa Park, IL, has a CCD sensor with the ability to capture low-light images, and features an enhanced dynamic range for color rendition and tonal qualities in captured images. The camera addresses microscopy applications such as polarized light, darkfield, Nomarski DIC, and fluorescence applications. The camera includes extended camera exposure range, low-light sensitivity, and true-color display and capture. All PAX-cams have a continuous white balance function, external mount for use as a macro camera, and USB-2 connectivity. The camera is suitable for applications such as microelectronics, semiconductor, LCD display manufacturing, materials sciences, and life sciences applications.

Network Camera

Axis Communications, Chelmsford, MA, offers the AXIS P3301 network camera with multiple H.264 streams. The fixed-dome camera uses the company’s ARTPEC-3 chip and is designed for unobtrusive video surveillance in exposed indoor environments. It features progressive scan and a wide dynamic range, providing images of both illuminated and low-light areas. Multiple H.264 streams and Motion JPEG streams can be provided simultaneously in full frame rate, or individually optimized for different quality needs and bandwidth restrictions.

Large-Format MWIR Lens

StingRay Optics, Keene, NH, offers a 50-mm midwave infrared (MWIR) large-format lens assembly with an optional microscanning and step-stare sensor capability. The lens can be a standalone solution for large-format detectors or used in conjunction with enhanced-resolution features. The lens is used with cooled cameras with focal planes up to 28 mm diagonal. The speed of the lens is based on an F/2.3 cold shield arrangement, and the 50-mm focal length is derived from the required 1-meter sampling area at an operating distance of 2.5 km. The lens provides diffraction-limited performance over the entire field of view.

Printed Flexible Solar Cells Provide Embedded Renewable Power

In the effort to produce inexpensive, easily manufactured sources of sustainable, renewable power, solar cells continue to be a major focus — particularly flexible solar cells that can be applied directly to surfaces. Flexible solar cells are nothing new, but the methods by which they are made have progressed significantly in recent years.

Performance of 1mm2 Silicon Photomultipliers

A silicon photomultiplier (SPM) is a new type of semiconductor detector that has the potential to replace the photo- multiplier tube (PMT) detector in many applications. In common with a PMT detector, the output of an SPM is an easily detectable current pulse for each detected photon and can be used in both photon counting mode and as an analogue (photocurrent) detector. However, the SPM also has a distinct advantage over PMT detectors. The photon-induced current pulse from a PMT varies greatly from photon to photon, due to the statistics of the PMT multiplication process (excess noise). In contrast, the current pulse from an SPM is identical from photon to photon. This gives the SPM a distinct advantage in photon counting applications as it allows the associated electronics to be greatly simplified. Identical pulses also mean that the SPM can resolve the number of photons in weak optical pulses, so-called photon number resolution. This is critical in a number of applications including linear-optics quantum computing.
