Vacuum UV Imaging Spectrometer

Vacuum spectrometers from McPherson (Chelmsford, MA) have a 670mm focal length. The spectrometers feature stainless steel housings and components for ultra-high-vacuum applications. The instruments readily achieve 10E-6 torr vacuum during operation with elastomer (Viton™ or Buna-N) seals. The McPherson models have master polished optics, multiple entrance and exit port locations, and high precision wavelength drives for wavelength reproducibility. Specialized high reflectivity coatings provide up to 78% reflective efficiency at wavelengths as short as 120 nm. The device has an f/4.7 aperture ratio (670mm f.l.). The tools are available in focal lengths of 0.67, 1.0, 1.3, and 2-meters.

Source Measurement Unit

Keithley Instruments (Cleveland, OH) has announced the Model 2401 SourceMeter® instrument, which is optimized for high-precision test applications such as current vs. voltage (I-V) characterization of photovoltaic (solar) cells, high brightness LEDs (HBLEDs), low voltage materials, and semiconductor devices, as well as resistance measurements. The instrument provides source and measurement unit capabilities at 20V and 1A signal levels. In a single enclosure, the Model 2401 integrates a highly stable DC power source with an instrument-grade 51⁄2 or 61⁄2-digit multimeter.

Submillimeter Achromats and Doublets

Bern Optics (Westfield, MA) has released submillimeter achromatic lenses as small as 0.20mm in diameter. The achromatic doublet, a compound lens consisting of two elements cemented together, can be custom engineered, ground, and polished to micron tolerances. In addition to careful control of the grinding and polishing of these complex lenses, Bern Optics verifies the centration of each element before and after cementing. They can be produced with or without specialized coatings to meet specific requirements.

Multispectral Imaging Camera

The SpectroCam™ Multispectral Imaging (MSI) Camera from Ocean Thin Films (OTF) (Largo, FL) combines a scientific-grade CCD array with a precision rotating optical filter wheel. With a single-point spectrometer, users can analyze spectral differences from sample to sample and then, by selecting discrete filters in and around spectral areas with the most significant differences, use SpectroCam to create an image that shows vivid contrast between the samples. The SpectroCam has a wideband CCD that is responsive from the visible through near-infrared spectrum. Image speed is 20 fps at full resolution, and the standard F-Mount configuration accommodates a range of lens choices, focal lengths, and fields of view. Each system includes a lens, eight standard interchangeable filters, and software.

HD Zoom Lens

Resolve Optics Ltd (Chesham, UK) offers the adaptable Z10-HDCF compact f/1.8 highdefinition zoom lens. The motorized 10x HD zoom lens is 87.5mm long and 45mm square. The Z10-HDCF, which is lighter than 500g, is also able to focus upon objects up to 450mm from the lens. A camera mount incorporates topside and back focus adjustment. A changeable rear cell enables the Z10-HDCF to be simply adapted for use on camera formats between 1/3- and 2/3-inch including 3CCD formats.

Laser Diode Driver

The laser diode drivers iC-NZN and iC-NZP from iCHaus Corp. (Bodenheim, Germany) operate laser diodes in both CW and spike-free pulse mode, with up to 155 MHz. The devices allow either the optical output power (APC) or laser diode current (ACC) to be controlled. Blue laser diodes can also be operated with iC-NZN. The maximum available laser diode current is 300mA, and the devices have an adjustable current limit. When the current limit is reached, it is signaled as an error message output which also indicates undervoltage and overtemperature. There is a safety shutdown function for the output stage in the event of overtemperature. The device can also be driven by either LVDS or TTL pulse signals. iC-NZN and iC-NZP have a standby mode with a low current consumption of < 50 μA.

Single-Photon Counter

AUREA Technology (Besancon, France) has introduced the SPD_B, a single-photon counting module used for short near infrared wavelengths [1,000 to 1,350 nm]. The SPD_B is an ultra-low-noise, highquantum- efficiency, and low-timing-jitter near-infrared single photon counter. The SPD_B includes a Geiger-mode InGaAs avalanche photodiode and thermoelectric coolers that ensure high detection efficiency up to 30%, a very low dark count rate of < 5.10-6 per ns gate, and a low timing jitter of < 180ps. The SPD_B comes with a graphical user interface compatible with LabView and C++.
