2.8 MP USB 3.0 Scientific Imaging Camera

Point Grey (Richmond, BC) announced a new addition to the Grasshopper3 scientific imaging camera family that features high quality, high resolution CCD sensors with a USB 3.0 interface. The new Grasshopper3 GS3-U3-28S5 camera models are based on color and monochrome versions of the fast and highly sensitive Sony ICX674, a 2/3" CCD featuring 4.54 micron square pixels and capable of sending 1932 x 1452 images at 26 FPS. The ICX674 sensor supports high definition (HD) 1080p30 imaging and uses Sony's EXview HAD CCD II™ technology—a further evolved version of the well-known EXview HAD CCD™ technology—to improve quantum efficiency and increase sensitivity, including into the near infrared. The GS3-U3-28S5 offers quantum efficiency of 67% at 525 nm, a dynamic range of 63 dB, dark current of 1.27 e-/second, and supports long exposures up to 30 seconds.

Photothermal Excitation For Atomic Force Microscopy

Asylum Research (Santa Barbara, CA), an Oxford Instruments company, has announced blueDrive photothermal excitation, an option available exclusively for Asylum’s Cypher™ Atomic Force Microscopes (AFMs). blueDrive makes tapping mode imaging simple, stable, and accurate. blueDrive replaces the conventional piezoacoustic excitation mechanism, instead using a blue laser to directly excite the AFM cantilever photothermally. This results in an ideal cantilever drive response in both air and liquids, which provides significant performance and ease of use benefits for tapping mode imaging.

DOP Meter

Using a patented maximum & minimum search technique, the DOP- 201 from General Photonics (Chino, CA) measures and displays the Degree of Polarization (DOP) of a light source in real time with high accuracy and wide dynamic range. While polarimeter-based systems are expensive and can be inaccurate for low-DOP sources, and polarization scrambler- based instruments are less accurate for high DOP sources, the DOP-201 accurately measures both low and high DOP. It is ideal for characterizing the performances of depolarizers and depolarized light sources, such as ASE and SLED sources and the pumps for Raman amplifiers.

Dual Inverted Selective Plane Illumination Microscope

A new dual inverted selective plane illumination microscope from Applied Scientific Instrumentation (Eugene, OR) generates 3d volumes with isotropic resolution (330) nm in all directions, offers axial resolution that is approximately 2x better than confocal or spinning disk systems, features acquisition rates up to 200 images per second or 2-5 volumes per second (roughly 10 times faster than spinning disk microscopes), achieves an approximately 7-10 fold reduction in photobleaching, and uses conventional mounting and glass cover slips. This microscope has multicolor capability and has been tested successfully on cells cultured on cover slips, cells embedded in collagen gels, and nematode and zebrafish embryos.

Infrared Imaging Camera Engines

Sofradir EC, Inc. (Fairfield, NJ) is introducing a new line of high performance infrared imaging engines. The Miniature Thermal Imaging Engines, labeled “MiTIE”, utilize a Sofradir cryogenically cooled MCT infrared detector. Three models will be introduced, the MiTIE MWIR-HD, a high definition 1280x1024 mid-wave imager and two VGA-format 640x512 engines, one for the long-wave spectral band (MiTIE LWIR) and the other for the mid-wave band (MiTIE MWIR). The MiTIE camera engines each include an integrated detector/dewar cooler assembly based on a 15 micron pitch, high performance Mercury Cadmium Telluride (MCT) IR focal plane array. The engines produce both analog NTSC/PAL video as well as 14-bit digital data (Camera Link and HDMI). The camera control interface is either USB or Camera Link.

Microspectrometer

The STS-UV Microspectrometer from Ocean Optics (Dunedin, FL) is a compact, high-performance spectrometer. Measuring just 40mm x 42mm and 24mm high, this product is optimized for applications in the ultraviolet (190-650 nm) including absorbance measurements, point of care diagnostics, emission spectroscopy and laser characterization. The STS-UV is anchored by a 1024- element detector in a crossed Czerny Turner optical bench. Its optical design and advanced CMOS detector elevate STS to performance levels comparable to larger and more expensive spectrometers. Previously released versions of the STS are also available for the visible (350-800 nm) and shortwave near-IR (650-1100 nm) regions of the spectrum.

Thermal Night Vision Systems

Senso Optics (Yokneam, Israel) has announced development of the world’s first "Thermal camera on Chip(TM)" for ADAS (Advance Driver Assistance System). ADAS is a driver warning system, designed to reduce accidents and lane departures by altering the driver. The ADAS also includes advanced features such as active braking and steering assistance. The new ASIC thermal system includes a SWaP-P (smaller, less Weight, power and Price) thermal miniature camera module with higher sensitivity. Senso Optics offers The ADAS to be able to support day, night, and adverse weather operating conditions. The system can even cope with extreme conditions such as heavy fog, smoke and smog. The system emphasizes live figures as human, animals and crossing pedestrians.
