The FLI MicroLine ML4240FI MB Mono is a high performance cooled monochrome astronomy camera using the Teledyne e2v CCD42-40-1-368 front-illluminated CCD sensor with a resolution of 2048 x 2048 pixels at 13.5μm. The 39.1mm diagonal field of view and large pixels make it an ideal match for long focal length telescopes such as PlaneWave CDKs and RCs. The ML4240FI is currently available with standard silicon and midband coatings: ML4240FI MB - back-illuminated Grade 1 sensor with standard midband coating. The ML4240's giant pixels, field of view and low noise make it an exceptional choice for critical low-light imaging applications. Like all FLI cameras, the ML4240 is designed for 24/7 operation, making it ideal for professional remote observatories where reliability is paramount. The ML4240 is available with a 45mm mechanical shutter as standard. With a peak quantum efficiency of 50%, large full well capacity of 100,000e- and dynamic range of 78.9dB, the ML4240FI is a versatile high-performance imager for the price. The regulated thermoelectric air cooler is capable of cooling the CMOS sensor to approximately 58°C below ambient temperature. The sensor temperature is regulated with ±0.1 °C precision. High temperature reduction and precision regulation ensure very low dark current for long exposures and allow proper image calibration. MicroLine series cameras are also plumbed for liquid circulation, further increasing cooling capabilities (external liquid circulation connectors sold separately). Additionally, an optional copper heatsink option is available for improved cooling efficiency. The ML4240FI features a USB 2 port for fast image transfers, with 700 kHz and 2 MHz digitization rates at 16-bits.
