Features

FPGA Design Solution

Xilinx (San Jose, CA) introduces the ISE® Design Suite 11.1, an FPGA design solution with fully interoperable domain-specific design flows and tool configurations for logic, digital signal processing (DSP), embedded processing, and system-level design. ISE Design Suite 11.1 has four domain-specific design configurations: the Logic Edition, DSP Edition, Embedded Edition, and System Edition. ISE Design Suite 11.1 shrinks development cycles up to 50 percent, reduces dynamic power consumption by 10 percent on average, and boosts tool performance by 2X for current generation Virtex-5 and Spartan- 3 FPGA-based designs.

Power Supply Reference Design

Fairchild Semiconductor (San Jose, CA) has introduced the RD212, a 200W DC/DC power supply reference design that offers high efficiency (up to 94 percent), and low noise characteristics due to its zero voltage switching (ZVS) technique. It provides a 24V output at 8A and protection functions such as over-voltage protection (OVP), overload protection (OLP), overcurrent protection (OCP), abnormal overcurrent protection (AOCP), and internal thermal protection (TSD).

Product of the Month: Lenses for Hostile Environments

Marshall’s Industrial and Security Division (El Segundo, CA) has developed a new series of pinhole lenses designed to protect employees when monitoring high temperature and/or hostile environments. The V-ZPL-HITEMP-A and V-ZPL-HITEMP-B zoom pinhole lenses permit reliable monitoring in temperatures up to 1000°. The V-ZPL12 series pinhole lens, available with motorized or manual zoom control, offers a 4-20mm angle of view and can be used for situations when the camera must be hidden from view. The V-PL150C, V-PL200C, and V-PL300C long focal lenses are designed for covert operations and can be used when looking through walls up to 14.81" thick.

Shadowgraph Camera

The Specialised Imaging Shadowgraph (SIS) camera from Specialised Imaging (Tring, UK) enables high resolution digital imaging of ultra-fast events in ambient and low-light environments. Integrating this camera with an ultra-fast, high-intensity spark source results in a sophisticated digital shadowgraph camera that offers instantaneous access to data. Comprehensive triggering functionality enables the SIS camera to be interfaced with a wide range of triggering devices.

High-Power Titanium Sapphire Coatings

Laser Components (Hudson, NH) offers solid state laser coatings with high damage thresholds, including coatings for Q-switched lasers at 1064 nm, 532 nm, 355 nm, or 266 nm. Coatings for short pulse lasers at 800 nm also exhibit excellent damage thresholds. The damage threshold measurement values were determined using a 780 nm Spectra Physics laser, featuring 1 kHz repetition rate and 140 fs pulse length, according to ISO 11254-2.

Highly Aspheric Mirrors and Lenses

Optical Surfaces Ltd (Surrey, UK) can generate highly aspheric parabolic mirrors with off-axis angles approaching 30 degrees and focal lengths as short as 100mm. They can also fabricate high-performance aspheric lenses with tight tolerances. Excellent performance is achieved with low surface scatter (20-10 scratch-dig) and high surface accuracy (lambda/20). The complex surface profile of aspheres offers excellent correction of spherical aberration and reduces other optical aberrations compared to a simple lens or mirror. On-axis parabolic mirrors produce collimated reflected light and are used in applications that require very fast focusing and high energy densities. Off-axis parabolic mirrors provide an unobstructed aperture allowing complete access to the focal region.

Machine Vision Camera System

Toshiba Teli America (Irvine, CA) has introduced the CS8581QF, a remote-head FireWire camera system for high-speed industrial imaging. The CS8581QF offers 133 fps at full 640 × 480 resolution (8bit monochrome), and partial scan modes over 430 fps. Based on a 1/3-inch progressive scan CCD, the CS8581QF features 7.4μm square pixels, an electronic shutter (1/50,000 to 2 sec), and random trigger shutter. The CS8581QF is comprised of a remote head camera and a central control unit (CCU) that can be mounted up to 2 meters apart from each other by a cable.

Sub-Miniature Resonant Optical Scanner

The SC-3 Sub-Miniature Resonant Optical Scanner from Electro-Optical Products (Fresh Meadows, NY) is an electromagnetically driven moving mirror device that deflects a light beam with a continuous sinusoidal motion. The scanning frequency range is from 100 Hz to 1000 Hz, fixed at any one value within the range. High device “Q” insures frequency stability, low reaction forces, and low electrical drive power. High flexural stiffness provides good resistance to shock and vibration, as well as low wobble, and good scan repeatability.

RTA Polygonal Scanners

Lincoln Laser (Phoenix, AZ) has announced a new family of RTA Polygonal Scanners. You may select a precision ball bearing motor for operation from 500 to 12,000 RPM or a self-generating air bearing motor for operation from 10,000 to 55,000 RPM. Polygonal mirrors are stocked in standard sizes from 18 to 90 facets. This family of mirrors and motors covers scan rates from 150 Hz to 85 KHz. Standard mirror coatings are for Infrared lasers. For a moderate extra cost and longer lead-time, users can specify a custom mirror for these motors and associated controllers.
