Custom lenses available in large format
Custom large-format lenses provide the high resolution over a large image format required by current and future generation megapixel linescan and area-scan sensors and cameras used in scientific and machine-vision applications. Unlike off-the-shelf lenses, custom lenses are designed to fully meet the optical and mechanical demands for high center-to-edge resolution, low distortion, and application-specific f-number performance. The lenses are also diffraction limited and feature a large depth of field, a wide field of view for close-up imaging, and high contrast.

Spherical camera system includes full hardware and software package
The anodized black “stealth” Ladybug3 model has been introduced to accommodate OEM customer requests for a more subtle appearance. Applications may include geographical information systems (GIS) for street-level viewing, high-end security and surveillance, and roadway or city infrastructure mapping. The spherical digital video system delivers 360° visual coverage using six Sony CCDs. It is designed for applications that require ultrahigh resolution, a weather-resistant case, direct FireWire connection, and the ability to synchronize to external devices such as an external trigger or light source. The camera is precalibrated to enable high-quality spherical image stitching and uses an embedded JPEG compression engine and 800-Mbit/s FireWire interface to stream full 12-Mpixel images at 15 frames/s to the host system. Each system comes complete with a Ladybug3 camera, a license of the Ladybug software development kit (SDK), FireWire card and cable, and mounting system.

The In-Sight 1403C model is a 2-Mpixel (1600 × 1200-pixel resolution) system that enables high-resolution inspection for a variety of color applications. In-Sight Explorer version 4.3 software introduces two new color tools. Color Match is a high-speed color sortation tool that provides 24-bit color resolution. Color Extract allows users to quickly train complex color models for state-of-the-art color analysis. The software also brings 6 new vision tools and 22 filters to the EasyBuilder configuration environment. Support for CC-link and MC Protocol has been added to the list of communication capabilities available in In-Sight vision systems.

Gigabit Ethernet cameras control motorized lenses
The integrated lens controller of the PicSight-AS-RTF and PicSight-Smart-AS-RTF allows the control of motorized zoom lenses over three independent channels. The three channels, normally configured for zoom, focus, and aperture can be set and read back. The interface has been designed to be compatible with most lenses available on the market (requirements: C-mount or CS-mount; direct current motors; and an input voltage up to 24 V). The cameras use the standard mini Camera Link connector, also known as SDR-26, for electrical connection to the lens. No additional connection to the host PC is required as all the commands are handled by the camera. The repositioning accuracy depends on the lens but is generally about 1%. The camera API provides full control over the lens for any type of application.
High-speed storage camera reduces need for external lighting components
The 63 × 63 × 64.5-mm MotionBLITZ EoSens mini high-speed recording camera features integrated GigE Vision and GenICam compatible interfaces. The variable plug position on the rear or left side of the housing simplifies installation in cramped conditions. Photo sensitivity of 2500 ASA monochrome and 2000 ASA color RGB enables use under low light conditions, allowing reduced lighting components and cost. Built-in fixed pattern noise (FPN) correction on a pixel-by-pixel basis corrects black level and dynamic deviation with the help of an internally stored reference image. The selectable, nonlinear dynamic transfer function delivers sharp detail in bright areas, compared to other cameras that saturate. Internal dynamic range is up to 90 dB with a resolution of 1280 × 1024 pixels and 506 frames/s with 8-bit monochrome output or optional 24-bit RGB with Bayer filter. Up to 113,000 frames/s can be achieved with reduced resolution.
Integrating sphere tests LED modules, light sources
The ISP 1000 integrating sphere has been designed with a 1-m diameter for precise measurement of the total radiant power and luminous flux of lamps. It is suitable for larger and more powerful LED modules with applications in solid-state lighting. Test samples can be placed inside the integrating sphere on a height-adjustable sample stage or in a lamp post with suspended or upright configuration. The setups enable the total luminous flux to be determined in 4π. Light radiation can also be launched from outside through a side port, allowing the heat dissipated from LED modules to be kept out of the sphere (appropriate for testing light sources with a forward radiation pattern). The design reduces the effect of compromising influences caused by baffles and ports to a minimum to improve accuracy.
CCD camera eliminates dark current
The “Clara” interline CCD camera is based on Sony’s 1.3-Mpixel ICX285 sensor. The company’s vacuum process, in addition to thermal management, has resulted in deep air cooling to -45°C for elimination of dark current, complementing a read noise floor of 3e- rms. Dynamic events can be followed with quantitative stability via low-noise 10- or 20-MHz readout modes, the data channeled through USB 2.0 interface. Proprietary iCam technology, comprehensive I/O functionality, and accurate hardware-generated timestamp support imaging applications, along with the robust design and accessible SDK for OEM integration.
Telecentric lenses feature less than 0.25% distortion
A series of telecentric lenses features standard reproduction scales of 0.2x (S5LPJ3599), 0.25x (S5LPJ3499), 0.33x (S5LPJ3399), and 0.5x (S5LPJ3299). The lenses offer a uniform working distance of 89 mm. The overall length is also identical to ensure interchangeability of the lenses. With a distortion less than 0.25% and a NA greater than 0.012, the lenses are suitable for various standard applications.
Reference design enables customization of smart cameras
A complete IP surveillance and machine-vision camera reference design based on the Blackfin BF526C processor is now available.

Cameras’ 0.03-lux sensitivity supports changing light conditions
Two new C3 Basic series 1.4-Mpixel cameras—the BM-141GE (monochrome) and the BB-141GE (Bayer color)—are equipped with a GigE Vision interface and are appropriate for outdoor applications with wide-ranging and continuously changing lighting conditions. They are designed around Sony’s ICX-285 2/3-in. progressive-scan CCD (1392 × 1040 pixels), which uses its 6.45-μm pixel size and microlens technology to provide overall sensitivity as low as 0.03 lux with low smear characteristics. It also features extended spectral response in the near-IR region, offering roughly four times the sensitivity of conventional sensors at a 945-nm wavelength. Circuit design and thermal management techniques deliver a signal-to-noise ratio greater than 58 dB. Both cameras feature an advanced Automatic Exposure Function that can simultaneously control gain, shutter, and lens iris. The cameras offer preset shutter speeds up to 1/10,000 s and programmable exposures as short as 63 µs for capturing fast-moving objects.
