FLI MicroLine 4240-1-DD Cooled Monochrome CCD Telescope Camera

About the FLI MicroLine CCD Telescope Camera Series

Goodbye Goliath! MicroLine CCD cameras are smaller and lighter-weight than the competition, but outperform them in key areas such as noise, frame quality, download speeds, bit-depth, and CCD cooling.

FLI MicroLine CCD cameras feature fast download speeds that simply leave the competition behind. Each component of the FLI MicroLine camera is designed and manufactured for a long life in the most demanding conditions. All major components are CNC machined and you're looking at only the highest quality electrical components and circuit boards with logo, serial number and focal plane indicators laser-etched on the surface - not printed. FLI designed photo-etched stainless-steel shutters are field-serviceable should they ever encounter damage and the sensor is hermetically sealed from dust and moisture.

What sets FLI MicroLine CCD Cameras apart is their small form factor. At 3.7 x 3.7 x 5-inches (HWL), the FLI MicroLine is a small camera with big camera capabilities! The MicroLine improves upon the highly successful FLI MaxCam design in a number of key areas including cooling, download speeds, clear aperture, and sensor capability.

Now, let's talk about FLI MicroLine CCD Camera Cooling... The FLI MicroLine's robust cooling design achieves a sustainable cooling performance of 50 to 55-degrees C below ambient temperature. The camera's CCD can be operated at Neg.30-degrees C with typical room temperatures and without the need for water cooling (sold as a separate option, visit the Accessories section for a list of choices) or special cooling sequences. Simply set the MicroLine cooling where you want it and the camera will do the rest - quickly and worry-free.

Conventional imaging cameras move the image data directly from the image sensor to the USB port, making them susceptible to added artifacts due to PC processing tasks, processor speed, and other PC-related issues. The MicroLine avoids these issues with its internal frame buffer, thus allowing an image to be quickly read out and downloaded to the PC. This allows the PC to take the image at whatever speed it is capable of without introducing any artifacts to the image.

When it comes the FLI MicroLine, you get system compatibility and mounting options as well as mechanical shutter, liquid cooling, and Anti-Dew Technology options that will help you trick out your camera the way you want it. The MicroLine line of CCD cameras is compatible with all FLI MicroLine E2V 42-40 Back Illuminated Deep Depletion Sensor with 43mm High Speed Shutter

FLI imaging accessories, including the Precision line of Color Filter Wheels and Digital Focusers. MicroLine camera adapters are available for microscope, telescope and machine vision connectivity.

About the E2V 42-40 Deep Depletion Sensor...

This model of MicroLine camera employs a top quality E2V CCD42-40 sensor that has been optimized for Near Infrared (NIR) usage. This sensor benefits from back illuminated architecture, working to produce high sensitivity and sharp images of a truly splendid quality. The sensor itself is very much so top of the line, with a the sensor boasting a respectable pixel array, and being of notable physical size in and of itself.

This model has been modified into a 'Deep Depletion' CCD, drastically increasing it's usefulness in the NIR spectrum. That is to say, this Back Illuminated CCD Camera has had it's active layer increased in extent to increase probability of absorption of photons in the NIR part of the spectrum. This makes this particular variant of the FLI MicroLine ideal for near infrared imaging of all kinds!

Additional Specifications of the E2V 42-40 Deep Depletion Sensor

  • Typical System Noise: 10 e- at 500 kHz; 14 e- at 2 MHz (23e- at 3 MHz)
  • Typical Maximum Cooling: 55-degrees C Below Ambient
  • Digitization Speed: 500kHz and 2MHz
  • Typical Dark Current: 24 e-/pixel/sec at Neg.35-degrees C
