FLI MICROLINE ML4720BI [MONO]

The FLI MicroLine ML4720BI Mono is a high performance cooled monochrome astronomy camera using the Teledyne e2v CCD47-20 back-illluminated frame-transfer CCD sensor with a resolution of 1024 x 1024 pixels at 13μm. Utilizing extremely low noise amplifiers, the ML4720BI is well suited to the most demanding scientific applications.

In this specialized design, half the sensor is covered with a metal mask; half is exposed to light. The exposed side of the sensor is centered in the camera aperture. The image is shifted under the mask in about 10ms.

The ML4720BI is available with different sensor types to suit a variety of applications:

• ML4720MB - back-illuminated sensor with standard midband coating.
• ML4720UV - back-illuminated sensor with enhanced coatings for UV imaging.

Note: The UV version of this camera cannot be operated in inverted mode and dark current is much higher than the midband version.

The ML4720'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 ML4720 is designed for 24/7 operation, making it ideal for professional remote observatories where reliability is paramount.

The ML4710 is available with a 25mm mechanical shutter as standard. With a peak quantum efficiency of up to 96%, large full well capacity of 100,000e- and dynamic range of 79.7dB, the ML4710BI is one of the most sensitive cameras on the market.

The regulated thermoelectric air cooler is capable of cooling the CMOS sensor to approximately 55°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 ML4720BI features a USB 2 port for fast image transfers, with 500 kHz and 2 MHz digitization rates at 16-bits. The UV version supports digitization rates of 500 kHz and 4 MHz.
