The 28-mm diameter, side-on PMT has a minimum effective area of 8 mm × 6 mm and a spectral response from the UV to near-IR (185–900 nm). The R9110 has a peak sensitivity at 450 nm, at which wavelength the detector’s multi-alkali photocathode has a radiant sensitivity of 90 mA/W, a luminous sensitivity of 525 µA/lm, and a high quantum efficiency of 24.8%. Dark current is typically 5 nA after 30 min storage. The PMT’s nine electron-multiplier stages yield a maximum gain of 1.9 × 107 electrons per photon, a rise time of 2.2 ns, an electron transit time of 22 ns, and a transit time spread of 1.2 ns. The R9110 is directly interchangeable with the company’s R3896 PMT.

The uncooled microbolometer module operates in the 7.5–14 µm spectral range and offers an excellent clarity of detail with no perceivable pixel structure. The IR-TCM 640 can handle frame rates up to 60 Hz and records sequences in realtime mode for output to an external image-processing system. The module has been designed as an OEM integration tool with such applications as thermal inspection systems, machine vision environments, property monitoring, and aerial photography and security purposes, including integration in space technology systems and military equipment.

It has all the necessary components to create versions of three different types of interferometers—Michelson, Mach-Zehnder, and Sagnac. The kit includes beam-steering mirrors, several translational stages, a motor-driven precision flexure stage, various beamsplitters, polarizers, and optical detectors. For light sources, the MI1-A offers a helium–neon laser, a variable-temperature red diode-laser, a bicolored LED, and a halogen lamp. The unit comes with a custom vibration isolation support system, a collection of samples, a gas cell with a pressure transducer monitor, electro-optical crystals, and a solenoid.

It delivers more than 3 W of output power at 800 nm. Designed to be pumped by the company’s V18 Verdi laser, the new source provides higher power across the entire Ti:sapphire tuning curve, with dramatic increases toward the edges at so-called difficult wavelengths. The increase in power is even more significant when the Mira HP is used to pump a synchronous optical parametric oscillator to obtain widely tunable visible and IR wavelengths. The new oscillator includes the company’s Optima control and diagnostics package, X-Wave optics, pump-steering optics for ease of pump alignment, integrated CW alignment cavity, and numerous ultrafast accessories.

The device is suitable for adjusting the brightness of displays and other similar components for optimum readability in the available light. A standard silicon photodetector will produce signals that are much higher for incandescent light bulbs than they are for fluorescent lamps, even though both light sources appear equally bright to the human eye. The SFH 5711 uses a new material system instead of silicon to solve the problem. The sensor consists of a light-detecting photodiode and an integrated circuit that provides amplification, temperature correction, and a logarithmic converter; the converter enables a brightness range of 3 lx to more than 30 000 lx.

The new indium gallium arsenide instrument has high-speed and regions-of-interest (ROI) windowing capabilities with an SWIR spectral response of 900–1700 nm. The all-solid-state camera features a room temperature 640 × 512 pixel focal plane array on a 25-µm pitch and can capture full-size images at 109 frames per second or image smaller ROI at more than 15 000 fps with a 100% fill factor. The SU640SDWH-1.7RT includes the company’s single 14-bit digital Camera Link–compatible output and a simultaneous analog video output. Sensors Unlimited’s image analysis software provides options for full control of four preset ROI, or windows, or variable windows.

Tests were performed using prototype devices with the company’s EZBright LED chips operating at 20 mA and a correlated color temperature of 6027 K. Lumens per watt is the standard used by the lighting industry to measure the conversion of electrical energy to light; typically, incandescent light bulbs are in the 10 to 20 lm/W range, while fluorescent lamps vary from 50 to 60 lm/W. Cree’s LEDs combine efficient indium gallium nitride materials with silicon carbide substrates for high-intensity devices that feature low forward voltage, exceptional thinness, low heat generation, and long life.

The new camera incorporates a back-illuminated 512 × 512 pixel EMCCD from e2v Technologies that features a quantum efficiency of better than 90%. It can capture more than 300 frames per second with binning and region-of-interest readout from 1 × 1 pixels up to full resolution. The Rolera-MGi can also be used to acquire high-resolution still images for dynamic ratio imaging, fluorescence recovery after photobleaching, and live-cell fluorescent protein imaging. The camera’s FireWire IEEE 1394 interface provides excellent connectivity and portability with laptop computers.

They cover a 1200–2000 nm optical spectrum, with a spectral uniformity of less than 13 dB. The high-power version provides an average output power of greater than 25 mW, with an optical power density of −17 dBm/nm; the corresponding figures for the low-power model are greater than 4 mW of output power and a power density of greater than −25 dBm/nm. The sources are based on the company’s 40 MHz repetition-rate, sub-100 femtosecond fiber lasers and use an all-fiber-integrated solution comprising robust telecommunication components and a management scheme that enables nearly transform-limited pulses.

Because it uses phase-shift technology, the MFPF is invariant to fiber bending and stray light and generates very little optical and electronic crosstalk. It can be configured with one- or two-channel LED excitation and avalanche photodiode detection with modulation frequencies to 100 kHz; luminescence lifetime measurements are possible from 200 µs to 0.3 µs. The instrument, with a filter-based wavelength selection, can be used with the company’s oxygen sensors to help mitigate index effects, eliminate ambient light, and improve system stability in dissolved oxygen applications.
