High Efficiency Double Spot Beam Splitter

LASER COMPONENTS (Bedford, NH) has introduced the HEDS (High Efficiency Double Spot) beam splitter. Double spot beam splitters are diffractive optical elements (DOE) used for separating an incoming laser beam into two identical beams. They are most commonly used in lithography as well as high power applications such as cutting and perforation. Until now, a small portion of light was lost in higher diffraction orders. Some applications cannot tolerate even a 1% loss, so this DOE boasts an efficiency well above the standard value of 81%. HEDS is available in wavelengths between 193 nm and 10.6 µm.

Scanning Electron Microscope

JEOL USA (Peabody, MA) has introduced a new Scanning Electron Microscope (SEM) that combines the performance of a Field Emission SEM with the simplicity of the JEOL InTouchScope™ SEM series. The new JSM-IT300HR features a rugged in-chamber specimen stage and large chamber to accommodate a wide variety of samples of different shapes, sizes, and weights. The specimen chamber’s twelve geometrically-optimized analytical ports allow for multiple detectors, creating a virtual nano-lab inside the SEM. Low vacuum capability is a standard feature and allows for imaging and analysis of all types of samples in their native state.

Optical Transmitter

The Micro ATx high-fidelity optical transmitter from APIC Corporation (Culver City, CA) combines an ultra-low-RIN (-168 dB/Hz) continuous wavelength (CW) laser (1530-1565 nm), a low Vπ amplitude modulator, a low noise amplifier, power conditioning and control electronics into a small yet rugged package (14 x 5 x 2 cm). When used in combination with APIC’s highly linear 20 GHz analog receiver, the resultant link performance, with a selectable low noise amplifier (LNA), has a gain greater than 8 dB; a noise figure (NF) lower than 8 dB; an SFDR ~ 111 dBHz2/3; and an RF bandwidth from DC through 20 GHz.

20 GHz Realtime Spectrum Analyzer

Saelig Company, Inc. (Fairport, NY) has introduced the Spectran HF-80200 V5 RSA rack-mounted real-time 9kHz-20GHz Spectrum Analyzer that can capture even intermittent signal transmissions. The Spectran HF-80200 V5 RSA scans from 9kHz to 20GHz in less than 20mS, so that even erratic transmissions or interference can be captured. The HF-80200 V5 is controllable through a USB interface or LAN/Ethernet, allowing continuous logging and streaming of almost any frequency range, and direct access to the analyzer through an Internet-connected PC. It offers AM and FM demodulation. All V5 rackmount spectrum analyzers are housed in a durable aluminum case and feature a built-in 20dB preamplifier.

Line Scan Cameras

Teledyne e2v (Chelmsford, UK) has developed OctoPlus, a new range of line scan cameras for Optical Coherence Tomography (OCT) applications. OctoPlus is based on new image sensor pixel architecture and is specifically tuned to provide the most accurate images of the retina and cornea; mapping tissue structure, measuring thickness and visualizing blood flow dynamics for diagnostics. Specific advantages of OctoPlus include a 250 percent larger field of view compared to the Food and Drug Administration (FDA) approved commercial Swept Source OCT (SS-OCT) and a +5dB signal-to-noise ratio (SNR) in comparison with equipment currently available in Spectral-Domain OCT (SD-OCT).

Red to Near-IR Enhanced Photodiode

Opto Diode Corporation (Camarillo, CA) has introduced the NXIR-5C, a red to near-infrared (NIR) enhanced photodiode with a circular active area of 5 mm2. With a spectral response from 320 nm to 1100 nm, the rugged photodiode is housed in a custom 4.7 mm x 4.9 mm ceramic carrier surface-mount device (SMD) package. The NXIR-5C provides superior responsivity with low reverse bias and high sensitivity at 0.62 A/W @ 850 nm and 0.35 A/W at 1064 nm. It has low dark current at 1nA, low capacitance of 5 pico-farads (pF) at 10 volts, and high shunt resistance greater than 100 MΩ.

Programmable Light Source

The RS-7-4 SpectralLED™ is a new digitally programmable, color tunable, calibrated light source from Gamma Scientific (San Diego, CA) that bolts directly on to existing image sensor testers from manufacturers such as Teradyne and National Instruments, and can be readily adapted to test head manipulators and handler instrumentation custom built by end users. The LED-based RS 7 4 offers a longer calibrated, stable lifetime than tungsten sources. Plus, the color temperature and spectral power distribution of the RS-7-4 can be rapidly varied through software control, and the output is extremely linear over its entire output range.
