Leica DFC365 FX offers excellent fluorescence documentation and fast time-lapse recordings under low light conditions. Based on the state-of-the-art Sony EXview HAD ICX285 sensor®, this cooled camera is exceptionally well suited for a wide range of fluorescence applications from basic fluorescence imaging to demanding applications such as TIRF, FRET, and Structured Illumination.
◇ Highly sensitive 1.4 megapixel Sony EXview HAD ICX285 sensor®.
◇Regulated Peltier cooling for excellent signal-to-noise ratio.
◇Two imaging modes: standard and nIR mode with at least 1.5 times enhanced sensitivity in the near infrared range of the spectrum （Quantum efficiency : 700-1000 nm ）.
Nir mode selection provides significant quantum efficiency enhancement and makes this camera ideal for observation CY7 CY5 fluorescent dye.
◇ Three pixel clocking rates (1.6 MHz, 20 MHz, 40 MHz) for full control of image quality and acquisition speed.
◇ groundbreaking acquisition speed with up to 21 fps in full frame and 122 fps in 8x8 binning mode.
◇ high-speed live cell imaging --- unique in this class of fluorescence cameras is the flexibility of three pixel clocking rates to define readout speed of the sensor. In addition to the 1.6 MHz-mode, the Leica DFC365 FX offers 20 MHz and 40 MHz. The 40 MHz mode in particular is dedicated to fast, real-time time-lapse recording. In combination with an overlapping mode, where the signal is read out while the next image is acquired, the user can easily execute high-speed experiments. With a maximum of 21 frames per second in full frame mode (1392 x 1040) or over 76 fps with 4 x 4 binning, the Leica DFC365 FX is the high-performer in this class of scientific fluorescence CCD cameras.
◇ ultimate cell protection --- Minimizing exposure times during time-lapse recordings is crucial to avoid photo-damaging the specimen. The sensor's high sensitivity and the careful selection of glass interfaces within the camera – in combination with nIR mode –are ideal requisites to protect cells and ensure optimal acquisition conditions during live cell imaging.
