Hi-Speed DM37 Deformable Mirror

ALPAO (Biviers, France) has developed the Hi-Speed DM37, with optimized temporal response, large stroke, and high linearity. Designed for applications requiring large corrections with a small optical beam, this entry-level mirror is interfaced with Matlab, Labview, and C/C++. Advanced users who wish to write their own drivers can benefit from the LEDBOX (option) to simulate the ALPAO Hi- Speed DM37. The DM37 has a clear aperture size of 7.5 mm and an operating temperature of 15-35°C. It features 37 actuators, with 1.5 mm distance between each actuator.

Continuously Variable Apodizing Filters

Edmund Optics (Barrington, NJ) has introduced continuously variable apodizing filters designed to eliminate undesirable intensity variations and create an even illumination profile in optical systems. The Bull’s Eye type filter features a high optical density in the center that decreases continuously to an uncoated edge in order to flatten the intensity profile of Gaussian beams. The Reverse Bull’s Eye type filter features a high optical density coating on the edge of the filter, which increases continuously to an uncoated center. EO’s standard Bull’s Eye type filters are available in 25- and 50-mm diameters with end densities of 1.0 and 2.0. They are manufactured using a B270 substrate to a dimensional tolerance of +0.00/ -0.20, a surface quality of 60-40, and a thickness of 1.50 +0.10. The filters are suitable for a design wavelength range of 400-700 nm.

Fiber-Coupled, Multi-Bar Module

A fiber-coupled, multi-bar module from DILAS (Tucson, AZ) delivers 300W through a cladding mode free QBH high-power 200-μm core diameter fiber with a low numerical aperture of 35%. The modules are packaged in up to 10-bar configurations and designed based on industry-standard conductively cooled bars, which are optically stacked and polarization-coupled. The product requires only industrial water for cooling. The modules have demonstrated a lifetime greater than 10,000 hours at a 300W CW operating condition. Custom wavelengths are available upon request. They are designed for direct diode applications as well as fiber and solid-state laser pumping.

Auto Focus Modules for CCD/CMOS Cameras

New Scale Technologies (Victor, NY) has introduced custom auto focus modules that install directly on board-mounted cameras and accept standard threaded lens assemblies. The compact lens motion module uses New Scale’s tiny SQUIGGLE® motor, TRACKER™ position sensor, and integrated electronics to provide high-resolution, closed-loop control. These components are combined with precise mechanical guidance in a robust polymer housing only slightly larger than the optical lens assembly. The module features a stroke of >2 mm, lens mass of up to 10 g, velocity of 7 mm/sec, and position resolution of 0.5 μm. The encoder type is a hall sensor array and incremental (absolute over 2 mm).

Scalable SPM Array for Large Area Detection

The SPMArray from sensL (Cork, Ireland) is the first four-side scalable low-light-detecting silicon photomultiplier array for use in markets such as medical imaging, homeland security, radiation detection, analytical instruments, and high-energy physics. The four-side scalable low light detector features a small form factor that makes the SPMArray suitable for weight and space constrained handheld radiation detection and identification systems. The package used in the SPMArray is not impacted by large magnetic fields and is designed to be magnetic compatible up to 3 Tesla.

PIXCI SI1 Frame Grabber

EPIX (Buffalo Grove, IL) has introduced a PIXCI SI1 frame grabber that allows image and control data transfer with minimal buffering over any PCI Express slot for low latency image capture and analysis. Featuring 190 MB/sec sustained data transfer rates and burst transfers at 250 MB/sec, the PIXCI SI1 captures images over a software- selectable pixel clock range of 25-70 MHz (typical). Higher pixel clock frequencies offer faster frame rates, shorter exposure times, and cable lengths up to 8 meters. Lower pixel clock frequencies enable slower frame rates, longer exposure times, and the use of longer cables. Bit packing allows more images to be captured to memory or hard drive; 12-bit images are reduced in size by 25 percent, while 10-bit images are reduced by 37.5 percent. The frame grabber supports 64-bit memory addressing for writing long-duration image sequences into terabytes of memory.

Fiber Laser Marker

TRUMPF (Farmington, CT) has unveiled the TruMark 5020, a new fiber laser marker that is suited for applications on metals and plastics with high speed and edge quality requirements. With high pulse frequencies and pulse-to-pulse stability, this laser marker is able to convert pulse frequencies of up to 1 MHz into a correspondingly high processing speed. For safety, the product includes a mechanical lock that prevents the laser beam from discharging between two marking procedures. The TruMark 5020 also features a modular design with the scanner, laser head, and power supply unit connected via plug-in connectors. The product comes with integrated laser power measurement and laser power calibration to maintain laser marking consistency.
