Processor deals four video displays
The 4View display processor can accept four video inputs and display them simultaneously in quadrants on a single 1280 x 1024-pixel monitor or deliver a full-screen display of any single input. Features include titling, borders, and both front panel and RS-232 controls. Options are available for auxiliary video-rate output, DVI digital output, and RGB display.

Telecentric lenses offer distortion-free imaging
Xenoplan bilateral telecentric lenses work with 2/3-in., C-mount, line, and matrix cameras for noncontact optical metrology applications. Telecentric in both object and image space, they come with manually adjustable iris and focus controls that lock securely and with front threads to accept filters. These lenses deliver a parallel beam path that makes the system insensitive to object size/location. By delivering distortion-free imaging over the entire object field, no software correction of results is needed. Mounting collar and fine-focus control can be rotated to accommodate unusual or cramped system configurations. Available magnifications include 1:1, 1:2, 1:3, 1:4, and 1:5.

Camera adds lens
The WV-BP134 1/3-in. monochrome CCD camera comes with the WV-LZF61/2 varifocal fixed iris lens for a variety of security and surveillance applications. The combined unit produces 380 horizontal lines and works under a minimum illumination of 1.08 lux at f/1.4. Other features include a signal-to-noise ratio of 46 dB, selectable backlight compensation, C or CS lenses, linelocked sync or automatic switching, and selectable auto iris. The 3- to 8-mm varifocal lens comes with a fixed iris that can be adjusted for desired scene dimensions. Panasonic Security Systems Group, Secaucus, NJ 07094; (877) 733-3689.
CMOS imager captures x-rays
The RadEye 2 x-ray specific digital imager contains more than 1 million pixels in a 49.2 x 49.2-mm active imaging area. In conjunction with two RadEye 1 photodiode arrays, the imager uses a rare-earth scintillator to detect x-ray and other energetic radiation ranging from 10 to 160 KeV. It runs from a single 5-V supply and requires an external master clock. An optional frame start input can be used to control the frame rate between 0.01 and 4.5 frames/s. Analog video is available sequentially via differential output ports at data rates to 2.5 MHz. Other features include asynchronous array reset, binning mode, and nondestructive readout.

System measures in 3-D
The YF10 is a noncontact 3-D video-coordinate measuring machine for inspecting miniature electronic parts. It comes with an IEEE-1394 digital CCD camera, metrology software, and 10:1 zoom lens optics or fixed optics. Twin halogen light sources transmit illumination via fiberoptics to obtain coaxial episcopic and diascopic illumination. A multi-LED programmable ringlight allows flexible settings. The system is equipped with 0.0001-mm resolution digital scales, servo-controlled stage and bridge assembly, and closed-loop feedback for precise positioning and repeatability. Measuring volume is 400 x 400 x 200 mm. Machine is directed by a joystick or mouse for continuous, incremental, and go-to movements. It runs under Windows 98 and a user-friendly graphical interface.

Lens operates smart InfiniMite lens can comprehend the proper working distance and magnification for a particular imaging task. Because the lens can directly focus from infinity to 39 mm at up to 0.75X, it can operate at 0.25X, 0.5X, and 0.75X. In combination with the company's 2X DL or LDL power module amplifier, the lens can achieve magnifications of 0.5 to 1.5X, and other standard intermediate magnifications.
