Switcher IC

Power Integrations (San Jose, CA) has introduced new members of its LinkZero-AX integrated offline switching integrated circuit family, offering main power output up to 6.5 watts. LinkZero-AX eliminates wasted energy by employing a power-down mode that turns off the auxiliary power supply when the application is idle, shutting down switch-mode operation and internal switch control circuits.

Graded Reflectivity Laser Mirrors

A new series of graded reflectivity mirrors from REO (Boulder, CO) enables precise spatial shaping of both the intensity and phase characteristics of laser beams. In graded reflectivity mirrors, the reflectivity and/or phase effects of the coating vary radially across the surface of the optic. REO offers these graded reflectivity mirrors on a wide range of substrates including fused silica, various optical glasses, ZnSe, ZnS and Si, for operation over the 266nm to 5µm spectral range. These mirrors are available with diameters from 0.25 inches (6mm) to 5 inches (127mm). Reflectivity pattern variations can be achieved down to a scale of approximately 1mm.

Planar Lightwave Circuits

FIBERTech RoMack (Williamsburg, VA), A LEONI Fiber Optics business unit, now offers a complete product portfolio of maximum performance and long-term stability Planar Lightwave Circuits (PLC) including single mode 1 x N and 2 x N broadband splitters with up to 64 channels, designed as monolithic components for the telecom wavelength range. These components are used primarily in passive optical distribution networks in the subscriber loop of the telecommunication networks (FTTH). Other applications of FIBERTech RoMack splitters are measuring systems, laser systems, and special PLCs with optical functions such as couplers, interferometers or pitch converter systems for measurement, sensor technology systems or optical signal processing. To expedite delivery of non-standard splitters, FIBERTech RoMack has designed a construction “kit” that allows them to manufacture an extensive functional variety of chips such as customized asymmetric or monolithic multiple splitters.

Off-Axis Parabolic Mirrors

Optical Surfaces Ltd (Kenley, Surrey, UK) can typically produce off-axis parabolic mirrors up to 600 mm in diameter with surface accuracy's to lambda/20 p-v depending upon off-axis angles. With proprietary polishing techniques, Optical Surfaces can, depending on the surface accuracy required, achieve the natural limit to the off-axis angle of around 25-30 degrees and surface micro-roughness on aspherics of ~1 nm rms. A range of coatings is available for standard and custom components from metallic – with protective overcoat – to multilayer dielectrics and ultra-hard coatings. Parabolic mirrors are the most common type of aspheric used in optical instruments. They are free from spherical aberrations, and thus focus a parallel beam to a point or a point source to infinity.

Dichroic Shortpass Filters

Edmund Optics (EO) (Barrington, NJ) has introduced TECHSPEC® Dichroic Shortpass Filters featuring a sharp cut-off wavelength and broad transmission and reflection ranges. TECHSPEC Dichroic Shortpass Filters are designed for a 45° angle of incidence. Light rejected by the filter is reflected at 90°, making the Dichroic Shortpass Filters perfectly suited for use in fluorescence applications and as spectral beamsplitters. Dichroic Shortpass Filters feature low polarization dependence, offer broad spectral ranges, and are made with a precision fused silica substrate. TECHSPEC Dichroic Shortpass Filters are available in 400 nm to 900 nm models with diameters of 12.5 mm and in 400 nm to 800 nm models with rectangular dimensions of 12.5 mm x 17.6 mm.

Multi-Channel Fiber Spectrometer

At the heart of Mightex (Pleasonton, CA) multi-channel spectrometers is a high-throughput flat-field imaging spectrograph. Multiple input fibers, each representing an independent signal channel, are aligned along the input slit of the imaging spectrograph. The spectrum of each channel is dispersed by a high-efficiency diffraction grating and then imaged onto a 2D CCD sensor. Light from each channel occupies different rows on the CCD sensor. All channels are exposed simultaneously, then rows associated with each channel are binned together to produce a spectrum for the channel. Fiber channels are spaced out properly to essentially eliminate crosstalk between adjacent channels. The standard CCD camera features a 1/2" 1.3MP Sony ICX205 imager with a 12-bit ADC. Exposure time (integrating time) can be varied between 50us and 200s.
