Wavelength Stabilized Lasers

Ondox, Inc. (Monrovia, CA) has added a 10mW, 405nm diode to its product line of wavelength stabilized lasers. The single longitudinal mode 405nm lasers have coherent length >1m, side mode suppression >25dB, and the wavelength is stable to approximately 3pm.. They are available in 5.6mm TO cans and fiber coupled modules. The 405nm lasers are used with standard photoresists for applications such as diffraction grating, embossed hologram fabrication, CD mastering, and microlithography.

Precision Filament Supply

The FIL-5V-3A precision filament supply, offered by UltraVolt, Inc. (Ronkonkoma, NY), is a center-tapped, non-isolated, low-voltage filament supply rated for 0 to 5 VDC at 0 to 3 Amps. The supply is designed for a variety of beam applications from electron guns to ion beams in devices such as scanning electron microscope inspection tools, focused ion beam workstations, and mass spectrometers. The FIL Series operates in either constant current (CC) regulated mode or constant voltage (CV) regulated mode. Between +26.4 VDC and +21.6 VDC, output line regulation is less than 0.01% in either mode. Units currently exhibit a temperature coefficient of 15ppm/°C in CC mode.

DC/DC Converter

The BPS Series high-voltage DC/DC converters from BEAR Power Supplies (Phelps, NY) power avalanche photodiodes (APDs) and piezoelectric actuators in optical systems, lasers, and other industrial and scientific instruments. The high-reliability isolated 1.5W converters come in an ultra-miniature encapsulated package of 0.5 × 0.5 × 0.4 inches (12.7 x 12.7 x 10.2 mm) and weigh 4 grams. The BPS Series converters have a single input voltage (configurable from 3 VDC to 15 VDC), a single output voltage (configurable from 50 VDC to 300 VDC), and operate from -55°C to +85°C with no heat sink or electrical derating required.

Ceramic Capacitor

Morgan Electro Ceramics (Bedford, OH) introduces a high voltage discharge ceramic capacitor with a high break-down strength up to 10 kVmm-1 and an inherently low dielectric loss. This combination of properties makes the capacitor ideal for circuits with high peak current and repetition rates, such as power-pulse applications for gas lasers used in the cosmetic industry. The ceramic discharge capacitor uses a strontium-titanate-based dielectric material. It has energy density storage of up to 6JKg-1. The high energy density of the capacitor is maximized over the rated working voltage (20 – 60 kV) and temperature range (–10°C to +85oC) by the low capacitance/voltage and capacitance/temperature coefficients.

Infrared Radiation Detectors for Thermographic Imaging

Thermographic imaging is accomplished with a camera that converts infrared radiation (IR) into a visual image that depicts temperature variations across an object or scene. The main IR camera components are a lens, a detector in the form of a focal plane array (FPA), possibly a cooler for the detector, and the electronics and software for processing and displaying images (see Figure 1). Most detectors have a response curve that is narrower than the full IR range (900 to 14,000 nanometers or 0.9 to 14 μm). Therefore, a detector (or camera) must be selected that has the appropriate response for the IR range of a user’s application. In addition to wavelength response, other important detector characteristics include sensitivity, the ease of creating it as a focal plane array with micrometer-size pixels, and the degree of cooling required, if any.

Real-Time Web-Based Image Distribution Using an Airborne GPS/Inertial Image Server

The use of geo-referenced imagery across the Internet is becoming prevalent thanks to the development of Web-based location servers such as Google Earth, TerraServer, and Yahoo Local. But users of these services are continually asking for more timely high-resolution data. Civil agencies such as firefighters, search and rescue teams, law enforcement, 911 emergency operations, border patrol operations, traffic monitoring systems, and geological survey crews — as well as the military — could benefit from a near-real-time, Web-based geospatial visualization capability.

Wide-VGA Cameras

PixeLINK, Ottawa, ON, Canada, has introduced the PL-B761 monochrome and PL-B762 color wide-VGA cameras that feature a global shutter CMOS sensor providing 60 frames per second at a resolution of 752 × 480 pixels. The 1⁄3" optical format sensor has a 6.0 μm pixel pitch, and a 50 μs minimum exposure time. The sensor also features high quantum efficiency in the near infrared. Both models are available with a choice of FireWire, Gigabit Ethernet, or USB 2.0 interfaces, eliminating the need for a frame grabber.
