Near-IR Cameras

FJW Optical Systems, Inc. (Palatine, IL) has released the Find-R-Scope model 85700 and 85706 Near-IR Cameras. The cameras utilize a 2.54cm (1”) PbO-PbS Super Infrared Vidicon and sophisticated electronics to provide uniform high resolution, low geometric distortion, and low noise performance without compromising long term stability. The BNC style coaxial output connects to external devices such as monitors, VCRs, frame grabbers, and image processors. The cameras provide the video output in either NTSC or PAL formats. With their standard C- mount, the cameras can utilize a variety of lenses and filters.

LED Lighting Modules

The Imaging Source (Charlotte, NC) now offers cost effective LED lighting modules, which seamlessly integrate with The Imaging Source USB, FireWire, and GigE cameras. The lighting modules feature very bright LEDs and direct connection to the camera. All parameters can be set via the shipped software, IC Capture and IC Imaging Control, or by custom built software. IC Capture is an end-user application, making it possible to save singular images and image sequences, and display live video streams. IC Imaging Control is an SDK, which consists of a .NET component, ActiveX control, and C++ class library for Windows XP and Vista.

Piezo Stages

Physik Instrumente (Auburn, MA) has extended its line of piezo stages for scanning microscopy applications. The P-737 Piezo Z-Focusing Stage is offered along with the stiffer, P-726 high performance microscope lens focusing system for large NA microscope objectives and the redesigned P-686 XY piezo motor positioning stage providing long travel ranges to 25x25 mm. The M-686 XY coarse-positioning stage can accommodate an XY / Z nanopositioning scanning piezo stage. The piezo stages are suitable for 3D imaging, Z-stack acquisition, autofocusing, scanning, and alignment tasks in microscopy and biotechnology.

Transmission Flat For Interferometers

Tower Optical Corp. (Boynton Beach, FL) has released a Transmission Flat, TxF, that is used in interferometers to verify the surface flatness of plano elements such as mirrors, windows, and prism surfaces. The transmission flat provides a reference wavefront which is compared to the returning, reflected light from the test object. The transmission flat has a surface with a reflectivity of 4% and another surface of 0.25%. This enables them to measure surfaces with 0.1% to 40% reflectivity. The 4-inch TxF mounts directly into the bayonet mounts of most interferometers.

Phototransistor Optocouplers

Everlight Electronics (Caroll-ton, TX) has introduced 4-pin SSOP phototransistor optocouplers. The phototransistor opto-couplers feature a low-profile (2mm) package, high isolation voltage (3750 Vrms), minimum creepage distance (5mm), wide operating temperature range (-55°C to +110°C), multiple current-transfer-ratio (CTR) bins, and high breakdown voltage (80V). The devices are well suited for use in DC-DC converters, battery chargers, general-purpose switching circuits, and programmable controllers.

Thin-Film Thermoelectric Cooler

Nextreme Thermal Solutions (Durham, NC) has released a thin-film thermoelectric cooler module, the OptoCooler UPF40, designed for optoelectronic applications with high heat-flux requirements. The module is suitable for the cooling and temperature control of optoelectronic devices such as semiconductor optical amplifiers (SOA) and laser diodes. The OptoCooler UPF40 module can pump a heat density of up to 72 W/cm2 at 25°C, and as a result, it can move a maximum of 3.7W of heat with an active footprint of only 5.1mm2.
