Fiber Laser Cutting System

Hypertherm (Hanover, NH) has released the HyIntensity™ Fiber Laser HFL015 cutting system, which includes a power source, cutting head, gas supply, operator interface consoles, motion controls, and software, all in one package. The single-emitter, diode-based design system operates on familiar Hypertherm control platforms, with pre-developed cutting processes that simplify table integration and operation. The power supply is smaller than CO2 laser systems, and the fiber laser delivery enables the beam to travel greater distances, allowing for installation on larger tables.

Infrared LEDs

A set of surface-mount, high-output infrared LEDs from ROHM Semiconductor (San Diego, CA) can be used in proximity sensor applications. The SIM-030/031ST and SIM-040/041ST surface-mount IR LEDs feature IR wavelength technology providing peak output of 850/870 nm. The 850/870 nm level is much closer to the peak wave sensitivity of phototransistors (sensors), thus achieving higher efficiency proximity sensing and energy savings of up to 66%. The SIM-030/031ST, the smaller of the two devices, has a 2.3 × 1.95 mm footprint and a height of 0.9 mm. With a forward current (IF) of 100 mA, the device delivers typical emission strength of 30 mW/sr (milliwatts per steradian). The slightly larger SIM-040/041ST (3.1 × 2.25 × 1.6 mm) provides 40 mW/sr, a typical emission strength.

Spectral Reflectivity Measurement System

Olympus Corp. (Center Valley, PA) has introduced a spectral reflectivity measurement system designed for use with lenses, prisms, flat glass, plastics, and electronic components produced by optical manufacturers. The USPM-RU III provides repeatable measurements in seconds, and without the need for backside coating. Spherical, aspherical, and flat surfaces can be accommodated without sample preparation. The system provides reflectivity measurements for wavelengths ranging from 380 - 780nm. Object color can be measured based on spectrophotometric colorimetry determined from prismatic reflectivity.

Vibration Isolation Workstation

The new Vision IsoStation vibration isolation workstation from Newport Corporation (Irvine, CA) is designed to improve ease-of-installation, setup, and lab space utilization. The workstation is available with platform sizes from 24 in. × 24 in. up to 36 in. × 72 in. to accommodate a wide range of applications. The Vision IsoStation is available in two load capacities — 500lb gross and 1,300lb gross — delivered by Newport’s high-performance I-125 and I-325 Series pneumatic isolators. Both versions reduce transmitted vertical and horizontal vibrations by 85 percent or more after 5Hz and by more than 95 percent after 10Hz.

Laser Power/Energy Sensor Shock Absorber

Ophir Photonics Group (Logan, UT) has announced the Shock Absorber, a mounting post designed to allow the operation of sensitive pyroelectric laser power/energy sensors in an environment with vibration. The mount smoothes out vibration and eliminates false triggering, reducing the sensor’s susceptibility to vibration from 2 to 10 times. The Shock Absorber includes a screw embedded in rubber that provides a flexible barrier between the post and the sensor head; this feature significantly reduces false triggering. The mounting post works with all Ophir energy sensors, including the PE Series of pyroelectric detectors.

f/#1.0 Athermalised LWIR Lens

LightPath Technologies (Orlando, FL) has introduced an f/#1.0 athermalised long wave infrared (LWIR) lens assembly with 10.65mm focal length, developed for uncooled infrared sensors using 8μm — 12μm infrared signatures. This lens assembly is a new addition to the already existing thermal imaging assemblies: f/#1.1 with 19 mm focal length and f/#1.3 with 14.9mm focal length. The opto-mechanical design, combined with the unique material properties of LightPath’s Black Diamond glasses, provide athermalization for temperature stability from -40°C to 85°C without adding to the cost. The f/#1.3 lens with 14.9mm focal length gives a 60 degree field-of-view when paired with a 15mm sensor with a 25 micron pixel pitch.

Pulsed Laser Driver

ILX Lightwave Corporation (Bozeman, MT) has released the LDP-3832 Pulsed Quantum Cascade Laser Driver. The LDP-3832 is designed specifically for quantum cascade lasers used in absorption spectroscopy applications and provides peak current up to 5A with a compliance voltage of up to 20V and adjustable pulse widths from 10ns to 1μs. The LDP-3832 also includes a precision 500mA DC current source with a modulation bandwidth greater than 10 kHz for biasing the laser. Laser protection features include redundant hardware and firmware current limits, transient protection, floating outputs, and safety interlocks.

Industrial Microscope Module

Carl Zeiss (Thornwood, NY) has introduced the Axio Imager Vario, a microscope module for industrial tasks where large samples requiring various contrasting methods, such as solar cells, wafers, flat panel screens or printed circuit boards, are examined. The sample space of the Axio Imager Vario has been adapted to object sizes with up to 300mm lateral and up to 250mm vertical extension. The microscope module is available in three versions. The Axio Imager.A2 Vario is a manual/encoded microscope module featuring a motorized turret focus. Axio Imager.Z2 Vario is fully motorized and features a motorized turret focus. A third variant without a focus drive is also offered for OEM clients who wish to utilize an external focus drive.

Photodiode Detectors

Hinds Instruments (Hillsboro, OR) has introduced a new generation photodiode detector family, the DET-200 series. Used in labs worldwide, Hinds’ detection systems are specifically designed for use with optical signals from DC to 1MHz over a spectral range of 200 to 1600nm. DET-200 series detectors offer adjustable gain while maintaining a constant offset of 5mV or less throughout all gain settings. This is a significant benefit in many applications. In addition, the size has been reduced by over half to 2" × 2" × 1" (50mm × 50mm × 25mm). The DET- 200 will  drive a hi-Z load from 0-10V and a 50Ω load from 0-5V. The DET-200 comes standard with a 15V power supply.

Single Fiber Assemblies

Allowing the use of fiber optics in potentially damaging environments, Fiberguide Industries (Stirling, NJ) has introduced its new standard line of single fiber assemblies. For general purpose use, Fiberguide’s furcation tubing is comprised of a Kevlar reinforced PVC sleeve over a polypropylene tube. Furcation tubing is non-conductive and protects fibers with a liquid-tight seal. For more specialized applications, Fiberguide offers stainless steel monocoil sheathing. The monocoil is vacuum compatible and resistant to tight bending, crushing, cutting, kinking and high temperatures. Both standard cable designs are rated for use at ambient temperatures. Single fiber assemblies are available with core sizes ranging from 50μ to 1000μ and wavelengths from deep UV (DUV) to UV-VIS and VIS-IR. Assemblies are also available upon request with ST and FC connectors, numerical apertures of 0.12 and 0.26, and continuous lengths up to 50 meters.
