Magnetic Encoder

Avago Technologies (San Jose, CA) has introduced the AEAT-601B compact, integrated, incremental magnetic encoder for speed detection, knob control, and rotary encoder applications. Housed in a protective plastic housing, it provides a resolution of 256 cycles per revolution and angular detection in a complete rotation of 360 degrees. The encoder has three-channel output enabling an index channel for each full rotation. It provides a closed-loop feedback system and is suited for use in systems such as motor and valve control systems, pan and tilt systems for security cameras, and thread winding machines. Features include contactless sensing technology, operating temperature range from -40 to 125 °C, three-channel output, single 5V supply, and direct connectivity through cable output.

Rotary Stage

The M660 high-speed, direct-driven piezomotor rotary stage from PI (Physik Instrumente) L.P. (Auburn, MA) is designed using PILine® piezomotor drive technology. The stage reaches top speeds of 720 degrees/sec and resolution to 40 μrad. A self-locking ceramic drive holds the position steady at rest, and a directly coupled precision optical encoder provides phase lag-free, backlash-free feedback to the servo controller. A USB interface, software, and driver package enable integration into existing applications.

Product of the Month: Ultra Compact Diode Laser

The new iBeam smart ultra-compact diode laser series from TOPTICA Photonics (Victor, NY) features digital and analog modulation; autopulse; a graphical user interface (GUI); high power levels (120 mW at 405 nm, 50 mW at 445 nm, 60 mW at 488 nm, 100 mW at 640 nm, 150 mW at 642 nm and150 mW at 660 nm); compact size (100 mm × 40 mm × 40 mm); single-mode fiber coupling; FINE (Feedback Induced Noise Eraser), which makes the iBeam smart completely insensitive to optical feedback; and a new SKILL function, which acts as a purely electronic “speckle killer” by decreasing the longitudinal coherence lengths of emitted light to a minimum.

Selective Wavelength Photodiodes

Opto Diode Corporation (Newbury Park, CA) has introduced the ODD-660W selective wavelength photodiodes. The device operates from 550-720nm, with peak response at 660nm, and features a spectral bandwidth of 80nm. A hermetically sealed photodiode offers low dark current without the need for optical filters. Applications include fluorescence detection, color sensors, daylight sensors, light barriers, and medical diagnostics. Systems and operating parameters are from -30 °C to 85 °C, with a lead soldering temperature of up to 260 °C.

Optical Vector Analyzer

Luna Technologies (Roanoke, VA) has introduced the Optical Vector Analyzer platform, (OVA 5000), a tool for loss, dispersion, and polarization measurements of modern optical networking equipment. It delivers single- measurement, all-parameter analysis of fiber optic components and assemblies up to 150 meters in length. A full C and L band characterization of all linear optical parameters can be completed in less than three seconds. The OVA uses swept-wavelength interferometry to measure all device characteristics in a single scan of a tunable laser. It characterizes all linear optical parameters including: Insertion Loss (IL), Polarization Dependent Loss (PDL), Group Delay (GD), Chromatic Dispersion (CD), Polarization Mode Dispersion (PMD), and Second Order PMD.

Microscope Focus Controller

Prior Scientific (Rockland, MA) has introduced a new focus-only control system for modern microscopes. The ES10ZE Focus Controller is suitable for applications involving extended focus or Z-stacking. The controller includes a clear display that shows the current position at all times while separate controls are provided for rapid movement up or down along with the facility to change the speed of the focus movement. A manual focus knob is also provided for manual fine focusing and ease of operation.

Camera Control Units

Toshiba Imaging Systems Division (Irvine, CA) has added two new camera control units (CCUs) designed to operate with the remote head, high-definition IK-HD1. The IK-HD1 model has an added DVI-I output on the rear panel, allowing customers to use HD control panels that accept DVI and/or HDMI signals, rather than more costly HD-SDI panels. The IK-HD1E CCU is designed to output HD-SDI and Y/Pb/Pr video signals in both 50 and 60 Hz.
