IX3 Breadboard and Filter Wheel Assembly

Prior Scientific (Rockland, MA) announced a new IX3 breadboard and filter wheel assembly for Olympus IX3 inverted microscope systems. Taking full advantage of the open access to the light path on the Olympus IX3 microscope, the IX3 breadboard and HF108SIX3 filter wheel module can be mounted and removed with ease. The combination is compatible with the IX3-ZDC module. Available as a separate part, the HP1719breadboard allows researchers to mount and insert any number of custom optics into the IX3 light path to create their own unique system. Having the filter wheel mounted below the nosepiece allows the user to not only switch between wavelengths at high speed, but also to see the fluorescent images through the eyepieces of the IX3 microscope as well as the camera. The HF108SIX3 filter wheel accommodates up to eight 32mm diameter filters. Drivers are available for cellSens and Metamorph software packages.

2MP Night Vision IP Camera

TRENDnet (Torrance, CA) recently announced a new 2-Megapixel PoE Day/ Night Dome Internet Camera, model TVIP262PI- A. The tamper resistant TV-IP262PI produces vivid 1280 x 1024 pixel (H.264 compression format) video in complete darkness for distances of up to 12 meters (40 feet). Manually pan the camera side-to-side and tilt it up-and-down to fix its final viewing position. Power and data are received through a single Ethernet cable using Power over Ethernet (PoE) technology. Integrated cabling allows for easy wall / ceiling mounting and the off-white IP camera housing blends into most environments. Other features include two-way audio support (mic and speaker sold separately), date/time text overlay, mask overlay to conceal sensitive areas, and image flip capabilities for upside down installations.

Laser Cutting Machine

Coherent, Inc. (Santa Clara, CA) has extended its integrated laser machine tool product portfolio with its new META platform, offering improved performance and greater ease-of-use. The META platform features a unibody chassis design. This rigid, single weldment provides improved mechanical stability for the system, resulting in faster cutting speeds and better positioning repeatability. In addition, the cutting bed on META platform products has been enlarged to accommodate standard European sheet sizes (1.25m × 1.25m).

Photodiode Modules

P-CUBE photodiode modules from Laser Components (Hudson, NH) enable precise measurements in a compact measurement setup. Low-noise, sensitive PIN photodiodes are housed in cubes that have an edge length of only 40mm. To integrate them into optomechanical setups, the cubes can be attached to a rod system. The following versions are available: GaP photodiode (190-570nm), Si photodiode (200- 1050nm), InGaAs PIN photodiode (800-2200nm). The programmable iAMP-700 current amplifier is directly connected to the P-CUBE with a BNC connector. The P-CUBE is also available with an optical FC connector. It is possible to achieve amplifications of 102-1011 V/A with the iAMP-700. By combining the P-CUBE and iAMP-700, the smallest amount of light can be detected reliably. The P-CUBEs require a bias voltage between -10 V and +10 V, obtainable directly from the iAMP

Laser Shutters

CVI Melles Griot (Rochester, NY) recently introduced SafeClose laser shutters, based on the proven rotor drive actuation technology modified to close on power down. The proprietary Rotor Drive actuator provides a reliable, multimillion- cycle operation and ability to withstand harsh environmental conditions, including wide temperature variations (from -40°C to +70°C), high shock, and vibration in a clean environment. Designed for laser safety and laser switching, the SafeClose shutter was designed to be highly reliable and to always maintain laser safe conditions by closing automatically when power is interrupted. The fail-safe magnetic return mechanism guarantees that the blade will reliably close upon signal interruption. The SafeClose shutter does not require a separate controller and a simple 9V DC signal is sufficient to actuate the shutter and hold it open.

Krypton Light Source

The ecoVis is a compact, lowvoltage light source (400-2500nm) from Ocean Optics (Dunedin, FL) with built-in cuvette holder that’s suitable for basic lab measurements in teaching labs and other research environments. The eco- Vis is small – just 95mm x 50mm and weighs 265g – and has a rugged solid alloy housing that helps to dissipate heat and in-line fiber ports for absorbance and fluorescence measurements. The light source has an integrated cuvette holder with 1cm pathlength and a versatile chromium-plated reflective insert that increases the output for fluorescence, holds the cuvette securely in place and can be adjusted through 90º to block the light path for dark measurements.

High Power Optical Fibers

Universal Clad (UniClad) optical fiber from Fiberguide (Stirling, NJ) is designed for integration into fiber based lasers and OEM systems performing high power transmission. The fiber uses a large core-to-clad ratio to reduce stress transfer to its core, maintaining laser beam quality and improving focal ratio degradation in lasers used for cutting, welding, drilling, soldering and marking. UniClad fiber has a pure fused silica core and doped fused silica cladding with a polymer coating. The fiber has a fixed 500μm cladding diameter for 100-400μm core sizes, and proportionately larger cladding for 600-800μm core sizes, to make laser alignment and splicing easier.
