Telecentric lenses focus on an object distance of 250 mm for 1/3-, 1/2-, and 2/3-in. CCD cameras and aim at maximum object diagonals of 25 and 50 mm. Lenses are broadband coated and come with M67 x 0.75 filter threads. MeVis-C measuring lenses come in focal lengths of 25, 35, and 50 mm for use with imagers up to a 1-in. format. Optimized at 20X with a range of 10X to infinity, these C-mount lenses provide a spectral range of 400 to 900 nm with a maximum aperture of 1.6 to 1.8. The 90° variofocus inspection lens is used in a macro mode to infinity using a focusing stick for working distances from 2 to 3000 mm (infinity). Aimed at a 1/2-in. format (8.1-mm image diameter) with a 50° angle of view, this right-angle lens can be adjusted from f/6 to f/16 and setscrew-locked.

PC_EYE_2+ quad-channel and RGB color frame grabber suits industrial and medical PCI-bus imaging applications. It provides four video input channels that can digitize four separate images in parallel from synchronized cameras with parallel acquisition into RAM and graphics. Drivers are provided for Windows 98/ME/NT/2000 and Linux with a setup program that supports board test and configuration. The board performs real-time acquisition of images or image sequences into main memory. It features an on-board sync generator, restart-reset capability, optoisolated trigger inputs, and pixel clock input. Four A/D converters digitize data with 8-bit resolution at rates from 5 to 32 MHz, and each converter can sample data from four input ports. Software support is furnished for third-party imaging tools such as AdOculos, Heurisko, Visilab, LabView, and Halcon. American Eltec Inc., Las Vegas, NV 89102; (702) 878-4085.
Frame grabbers do Camera Link FlashBus DX-CL single-input and FlashBus DX-CL2 dual-input frame grabbers use the Camera Link interface to capture RGB and monochrome images from digital area-scan cameras. They deliver consecutive frames of video in real time at PCI bus transfers of 100 Mbytes/s into system or display memory without intervention from the host CPU. A flexible FPGA architecture provides two video DMA channels. Simultaneous dual asynchronous capture from two monochrome area-scan cameras provides up to a 10-bit pixel depth. Single-input capture is provided from 8-, 10-, 12-, 14-, 16-, and 24-bit RGB area-scan cameras. Pixel clock rates can run up to 40 MHz. Camera control interface provides support for asynchronous trigger and long-term exposure functions. The frame grabbers include on-board processing, serial communications support, and a 0—10-V programmable DAC output. Integral Technologies Inc., Indianapolis, IN 46256; (317) 845-9242.
CCD camera sees color CV-M77 progressive-scan, single-chip, 1/3-in. color CCD camera provides an RGB output, 1034 x 779-pixel resolution, pulsewidth control, edge preselect, and long-time exposure trigger modes. It provides 25 full frames/s and a Bayer pattern RGB primary mosaic filter. Via an RS-232C interface, the camera can select shutter speeds from 76 µs to 40 ms in 50-µs steps, which complements 12 fixed shutter speeds from 1/25 to 1/10,000 s. Short ASCII commands allow set-up and configuration of camera modes and parameters. JAI America Inc., Laguna Hills, CA 92653; (949) 472-5900.
Software adds functions Aphelion version 3.1 imaging software provides Aphelion ActiveX components for image capture, processing, and display in Visual C++, Visual Basic, and Borland JBuilder. The graphical user interface includes a Visual Basic-compatible scripting language, a chart server, and more than 450 image-processing and image-understanding operators.

Line of lights DL3316 and DL37100 LED axial diffuse illuminators deliver uniform reflected light for 25- and 75-mm fields of view, respectively. The DL3316 unit is 33 x 33 x 97 mm for small-space inspections; the DL37100 unit is 88 x 89 x 156 mm for large-space inspections. LED linelights provide uniform high-intensity output in beam lengths or 3, 6, 12, 18, and 24 in. and working distances from 0.5 to 5.0 in. with beam widths of 1/8 to 5/8 in. For off-axis lighting, RL1420 LED ringlight comes with a 55-mm inner diameter. All illuminators incorporate the company's Evenlite aiming technology for targeted lighting. Heat-sinking the LEDs eliminates the need for a fan. Illuminators can be powered by the company's Signatech supplies or by user-supplied 12 and 24 Vdc.
