Diagnostic Instruments Digital Cameras
A broad array of cameras, for a broad spectrum of needs
The Diagnostic Instruments INSIGHTTM family of digital cameras provides a feature packed imaging system for most documentation applications. When you buy an Insight camera, you benefit from engineering expertise gained from Diagnostic Instruments’ research and development into high-end quantitative camera designs. The result is low noise, high-speed image captures that produce stunningly clean views of your specimen. Some of the true strengths of the Insight system comes from the SPOT software that not only makes it easy to control the sophisticated hardware, but takes you well beyond image capture. Powerful, yet intuitive software functions provide many microscopists with all the tools they will ever need.
The FLEXTM family of digital cameras combines acquisition flexibility with category-leading specifications to set the new benchmark for high-resolution documentation applications. With Flex shifting-sensor technology, you can select the resolution dependent on your needs: single-shot 4MP capture for live/moving specimens, 4-shot 4MP full color sampling for high magnification-fixed specimens, 16-shot 16MP for low magnification-fixed specimens, or a 64MP color (using image double) mosaic image for smooth, large-format publication. Flex monochrome goes even farther, providing 9-shot, 36MP resolution and 16-shot, 64MP true resolution without image doubling. With the higher QE of the monochrome CCD and 14-bit data capture, this is a perfect imaging camera for high-resolution industrial inspection applications. Flex cameras are an excellent solution for capturing images of both brightfield and fluorescence specimens. Making all this power and flexibility easy is SPOT software, which combines real-time viewing and image capture with essential post processing, storage and simple automation.
The SPOT RT3TM family of digital cameras is the newest version from the popular SPOT RTTM line of cameras, combining improved performance with Firewire® connectivity. With an effective differential cooling of -43°C, and improved CCD sensor design, dark current has been suppressed to 0.003 e/p/s. This is a 20x improvement, making the RT3 an excellent performer for longer exposure fluorescent applications. Image acquisition rates have been tripled, while reducing read noise by over 25%, providing even higher dynamic range when combined with the deep pixel wells of its Kodak KAI 2020 CCD. The RT 3camera is offered in monochrome, color mosaic, and user-selectable color/monochrome slider models, making this a great performer for both documentation and quantitative research.
The PURSUITTM family of solid, low-noise 4MP digital cameras provides a large field of view without need of reduction optics. Low-noise readout and regulated cooling facilitate critical quantitative applications. The XPLORERTM family of 4MP cameras delivers top performance specifications on all fronts, including superior regulated cooling, making it the obvious choice for labs that need to perform a wide variety of critical quantitative applications including long exposure, low-light imaging. Control of these cameras can be accomplished by SPOT software for simple to moderately complex imaging tasks, or by using a number of sophisticated third party applications that specialize in complex control, automation, and analysis of whole experiments. Both cameras are available in Slider versions.
The BOOSTTM family of EM CCD cameras utilizes Electron Multiplication technology to deliver supreme performance for extremely low light microscopy applications. Electron multiplication gain of up to 1000x offers the capability to extract extremely faint signals without the need for an image intensifier. The Boost camera is offered in three base models of CCD formats and includes front-illuminated and extremely sensitive back-illuminated (>92% QE) versions. Flexibility is a hallmark of this camera line with selectable read speeds, adjustable vertical clocking, adjustable True Linear gain multiples, electron multiplying and non-EMCCD read options. Cooling options allow this camera system to achieve ?100º C cooling while vacuum-sealing technology insures that cooling performance will be maintained for years to come. Data can be acquired at up to 16 bits with less than one percent non-linearity, assuring data integrity for even the most demanding imaging applications. Using electron multiplication technology, phenomenal frame rates (over 5,000 sub-frames per second)can be achieved with effectively negligible read noise.

The ASI LS-50 Linear Stage (pictured, lower) provides sub-micron accuracy, and derives precise control through the use of closed-loop DC servomotors employing high-resolution rotary encoders for positioning feedback. The stage utilizes crossed-roller slides, precision lead-screws, and zero-backlash miniature geared DC servomotors for smooth and accurate motion. The unit offers 50 mm (2″) of precise travel, can be used either vertically or horizontally, and can carry loads up to 4.5 Kg (10 lbs).
The unit can be configured with a number of lead screw options. In the standard configuration, and using ASI’s MS-2000 control electronics, resolutions in the 50- to 100-nm range can easily be obtained. Repeatability factors of less than 300 nm (typical) are obtainable with optional linear encoders, compared with 800 nm which is typical with other rotary encoders.
The MS-2000 controller accepts industry standard commands, provides automatic backlash correction, and allows RS-232 or USB communication with a host computer.
