Linear-Array PMT Modules

Linear Array Photomultiplier tube (PMT) modules from Hamamatsu Corporation (Bridgewater, NJ) offer high cathode sensitivity, high gain, and high-speed response. The H11451 series features 8 channels in a linear format, with each channel's photosensitive area measuring 2.0mm (W) × 2.5mm (H). Two spectral response ranges are available: 300-880nm (peak at 420nm) and 300-920nm (peak at 630nm).

Pentaprisms

REO (Boulder, CO) offers pentaprisms with coatings optimized for demanding laser applications, such as target designation and range finding. The pentaprisms feature dielectric antireflection and high-reflection coatings manufactured using ion beam sputtering (IBS) technology. The densified films exhibit laser damage characteristics of over 12 J/cm² in 20 nsec pulses at 1064nm. IBS technology also enables optical coatings with complex spectral characteristics, including multi-spectral operation, where high performance is required at several widely spaced wavelengths or wavelength bands (for example, both 1064nm and 1573nm).

Femtosecond Laser

Based on diode-pumped disk laser technology, the femtosecond laser JenLas® D2.fs from JENOPTIK Laser Technologies Corp. (Brighton, MI) emits high pulse energies of 40 μJ at 100 kHz repetition rate, and can operate in the 30-200 kHz range. Its working temperature range has been extended to 15–35 °C. The laser offers beam quality of M² ≤ 1.25 near the theoretical limit and pulse duration of ≤ 400 fs. Testing includes climate and shock tests, immunity to external electrical noise, and compliance with the low EMC standards for electrical noise emission.

Filter Modeling Tool

MyLight, an online filter modeling tool from Semrock (Rochester, NY), provides users with the ability to characterize optical filters under varying theoretical conditions in real time. The technology offers answers on how filters behave under particular angles of incidence, polarization, or cone half angle. MyLight data can also be saved, re-drawn, and printed.

Network Activation Kit

AFL (Spartanburg, SC) offers network activation kits designed to support installation and commissioning of optical equipment in telecom, broadband, and other single-mode optical fiber networks. All network activation kits include the AFL VOA6 single- mode variable optical attenuator, the AFL One-Click Mini cleaner, and AFL’s OPM4-4D optical power meter. Each broadband activation kit also features an AFL OLS7-FTTH optical light source, and all equipment is calibrated for industry- standard upstream and downstream FTTx signals. Telecom activation kits also include an AFL OLS2-DUAL optical light source. Equipment is calibrated for standard telecom wavelengths. Network activation kits can be ordered with hard-sided or soft, padded carry cases.

Transmission Electron Microscope

A 200kV transmission electron microscope from JEOL (Peabody, MA) delivers nanoanalysis for process and quality control of mass-produced semiconductor and materials samples. The multi-function JEOL JEM-2800 features high resolution imaging in TEM, STEM, and SE modes; ultrasensitive elemental mapping with a large angle Energy Dispersive Spectrometer (EDS); Electron Energy Loss Spectroscopy (EELS) for chemical analysis; critical dimension analysis; tomography; and in situ observation of samples. The TEM functions without use of the traditional fluorescent screen on the electron column. The JEM-2800 speeds specimen observation through automatic functions including adjustment of focus, astigmatism, contrast, brightness, crystal zone axis alignment, and height. The JEM-2800 has an operator navigation system and on-screen operating guide. Additional features and key specifications of the JEM-2800 include a Schottky field-emission electron gun; stable eucentric side-entry goniometer stage; a magnification range of 100x to 150,000,000x using STEM; 0.1nm TEM resolution; and 0.20nm BF/DF STEM resolution.
