Hamamatsu Introduces the New ORCA-Flash2.8 Scientific CMOS Camera

BRIDGEWATER, New Jersey, March 17, 2010 - Hamamatsu has introduced the new ORCA-Flash2.8, its first
high-sensitivity digital camera based on a next-generation scientific CMOS
image sensor. Designed for low-light imaging at high frame rates, the
ORCA-Flash2.8 combines high resolution, high sensitivity, high speed, and low
noise at an affordable price.

At the camera's core is a new scientific CMOS image sensor, the FL-280,
which features 2.8 megapixels and a pixel size of 3.63 x 3.63 microns,
ensuring high resolution. The sensor's wavelength sensitivity ranges from UV
to visible, with peak sensitivity (over 60% QE) at about 450 to 500 nm. In
addition to high sensitivity, the sensor features low readout noise,
typically 3 electrons r.m.s. The sensor's design keeps the readout noise
minimal even at very fast readout speeds, unlike traditional image sensors.
The FL-280 sensor also has low dark current. Because of its intrinsically low
dark current, the sensor requires cooling to +5 deg C only.

Built for high-speed imaging, the ORCA-Flash2.8's readout speed ranges
from 45 frames/second at full resolution up to 1273 frames/second with
sub-array readout. Other features of the camera include external trigger
functions, real-time corrections, and analog gain. The camera is designed for
quantitative measurements with 12-bit output, and it interfaces with a PC
using a CameraLink frame grabber board (included with the camera).

The ORCA-Flash2.8 is suitable for a wide variety of applications. These
include life science imaging such as ratio imaging, FRET, FISH, TIRF
microscopy, and real-time confocal microscopy. Other applications include
semiconductor inspection and industrial imaging.

Hamamatsu is exhibiting the ORCA-Flash2.8 at Analytica 2010 in Munich,
Germany, from March 23 to March 26 (booth number A2 420). Demo cameras will
be available from Hamamatsu Corporation in May 2010.
