10 to 1000eV Spectrometer

The new McPherson (Chelmsford, MA) Model 248/310 spectrometer can easily make spectral measurements around 13 nanometers and throughout the extreme vacuum ultraviolet and soft x-ray wavelength region. It is ideal for work from 10eV to more than 1000eV. The spectrometer features one meter focal length optics built into a compact Rowland circle instrument. Grazing incidence angles used in the instrument deliver high reflective efficiency. For direct detection of extreme vacuum ultraviolet and soft x-ray wavelengths, windowless back illuminated CCD’s are used. Sensitivity of CCD’s at short wavelengths can surpass that in the visible spectral region. The CCD’s aggressive thermoelectric cooling also reduces readout noise. When gated detection is required, open microchannel plate intensifiers are available.

Optical Fiber

Polymicro Technologies (Lisle, IL) has successfully developed a broad spectrum optical fiber with a low -OH pure silica core that demonstrates significantly reduced content of UV defects and other UV absorption centers. Polymicro’s proprietary FBPI fiber leverages the benefits and mitigates the limitations of standard optical fibers. Featuring improved transmission properties over a much wider spectral range, the silica-based, broadband FBPI fiber is available in a range of densities and can be produced in core diameters from 50-600 μm.

Fast Axis Collimators

Edmund Optics (EO) (Barrington, NJ) has introduced new fast axis collimators. These versatile lenses are designed for beam shaping or laser diode collimation applications. Fast Axis Collimators are compact, high performance aspheric cylindrical lenses, designed for fast axis collimation. The combination of aspheric cylindrical lens designs and high numerical apertures (N.A.) deliver uniform collimation of the entire laser diode output while maintaining excellent beam quality. Fast Axis Collimators feature a standard AR coating for 790-990 nm and provide greater than 99% transmission across the designated spectral range. Fast axis collimators measure 12 mm long and are available in five models with focal lengths of 0.29 mm, 0.365 mm, 0.59 mm, 0.91 mm and 1.49 mm.

45W UV Laser

Spectra-Physics® (Santa Clara, CA), a Newport Corporation brand, recently introduced Quasar 355-45, a UV laser that delivers >45W (225 μJ) at exceptionally high repetition rates. The laser features TimeShift™ technology for pulse shaping and burst-mode operation as well as programmable pulse widths from 100 ns over repetition rates from 0 to 1 MHz – factor of 2 improvements in repetition rate range and minimum pulse width over the recently introduced >40W Quasar 355-40.

2 GHz RF Source

Crystek Microwave (Fort Meyers, FL) has announced the release of a 2 GHZ RF Source, the CRFS75-2000. Crystek designed the module using proprietary circuitry and SAW (surface acoustic wave) resonator technology to provide ultra-low jitter/phase noise performance with true SineWave output. The resulting source features -134 dBc/Hz phase noise at 10 KHz offset and a noise floor of -164 dBc/Hz. Crystek's CRFS75-2000 comes in a 0.75 in. x 0.75 in SMT package. With 5 V input voltage, it generates a true-sinewave with +5 dBm min. output power. The new source has no sub-harmonics; second harmonic is -20 dBc typical. Frequency accuracy is rated at +/- 150 ppm. The CRFS75- 2000 operates from -40°C to +85°C.

C40 Heatsink System

Ohmite Manufacturing (Arlington Heights, IL)recently introduced their high performance C40 Heatsink System with modular cooling benefits. Designed to provide engineers with a variety of cooling options, the C40 heatsinks feature flexible board mounted modular assembly that can be used in conjunction with up to four TO-247 and TO-264 power resistors, or similarly packaged passive and active components. These 58mm heatsinks can be used individually or in compact paired configurations. Patented camming clips (sold separately) easily secure the devices in place without the need for holes or screws. In order to create active cooling and enhance their thermal capacity in back-to-back paired operations, the C40 heatsinks include pre- configured mounting holes to accommodate a standard 40mm x 40mm fan.
