  • C11440-50B CMOS Camera
Mar 2011
Hamamatsu CorporationRequest Info
BRIDGEWATER, N.J., March 3, 2011 — Hamamatsu Corp. has introduced a board-level camera for OEMs. The C11440-50B is based on a next-generation scientific CMOS image sensor and combines high resolution, sensitivity and speed, and low noise.

At the camera’s core is the FS-280 scientific CMOS image sensor, which features 2.8 megapixels and a pixel size of 3.63 × 3.63 µm, ensuring high resolution. The sensor’s wavelength sensitivity ranges from the UV to the near-IR, with peak sensitivity of >60% quantum efficiency at ~450 to 500 nm. The sensor features low readout noise of 3 electrons rms, typical. Its design keeps the readout noise minimal, even at readout speeds ranging from 45 fps at full resolution to 1273 fps with subarray readout. The image sensor has a wide dynamic range of 4500:1.

Two IEEE1394b (FireWire) interfaces offer low-cost communication and power, while external trigger options enable seamless integration with the OEM customer’s equipment. The camera is suitable for a variety of imaging applications, including life sciences imaging; high-speed calcium imaging; and Förster resonance energy transfer, fluorescence in situ hybridization, total internal reflection fluorescence and real-time confocal microscopy. Other applications include semiconductor inspection; industrial, ratio and time-lapse fluorescence imaging; live cells expressing green fluorescent protein; micromorphotological observation; failure analysis; and x-ray scintillator readout.

External trigger and timing output functions include global exposure, synchronous readout and start trigger; trigger delay; and programmable and global exposure timing, and trigger-ready output.

Other features include 2 × 2 binning, analog gain of 1× to 8× in 256 steps, an 8- or 12-bit analog-to-digital converter, exposure time of 20 µs to 1 s and a C-mount lens.

analog-to-digital converter
A device that converts an analog signal, that is, a signal in the form of a continuously variable voltage or current, to a digital signal in the form of bits.
Combining adjacent pixels into one larger pixel, resulting in increased sensitivity and lower resolution, or, in image analysis, excluding objects based on shape, position or area.
A standard lens interface initially made for 16mm movie cameras and now used primarily on closed-circuit television cameras. It is a 1-in.-diameter, 32-thread-per-inch interface with a flange-to-image plane distance of 0.69 in.
A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
