FLI Proline CCD Cameras
The ProLine Imaging System sets a new standard in CCD camera performance and flexibility. As FLI's flagship imaging system, the Proline cameras feature user selectable download speeds, choice of cooling base configurations, and a separate hermetically-sealed chamber for the CCD and electronics. Every major component of the ProLine is CNC machined to ensure a long life in the most demanding conditions. The ProLine base / heat sink, shutter housing and front flange are each machined from a single piece of high-grade aluminum. (Being part of the base assembly, even the ProLine fan cover is CNC machined!) The electrical printed circuit boards use only the highest quality components and are protected from harsh environment without the need for conformal coatings.
Breaking new ground in download speeds, the FLI ProLine provides the user with extremely fast user-selectable download speeds. You can download images at 12 mega-pixels per second for focusing. This means that an un-binned image can be downloaded to your PC in as little as 1 second! For imaging, the download time can be slowed to reduce the noise in the final image. The ProLine achieves a sustainable 65°C cooling performance. This means you can operate your camera at -30°C with ambient temperatures of up to 35°C (84°F) for lowest dark current and its attendant noise. No additional cooling or cooling sequence staging is necessary but a liquid cooling option is available to achieve a wider range.
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. Each ProLine camera has an internal memory capacity so that the imaging chip can 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. Through sophisticated design and production techniques, the ProLine image sensor is accurately aligned so that the imaging chip is perpendicular to the optical path without shims or other post-assembly adjustments. This is crucially important as chips get larger to insure the entire frame of your image is in focus.
FLI ProLine CCD Camera Feature Overview...
- The ProLine standard window has the highest transmittance available (~97% to below 390 nm). Systems that require higher transmittance are supplied with windows with extended high transmittance to 180nm.
- The ProLine shutter avoids the issue of particles falling from the shutter onto the sensor surface.
- ProLine is setup with external triggering for those applications that require it.
- The ProLine allows a user to power and connect an FLI focuser and filter wheel directly - avoiding long messy cables.
- ProLine standard air cooled base provides up to 65 deg C differential.
- Selectable download speeds up to 12 mega-pixels/seconds and On-board frame buffer standard
- CCD overscan capability, Field upgradeable firmware and USB 2.0 high speed serial interfaces
- Triple TEC Cooling for true, maintainable 65ºC cooling and separate hermetically-sealed chambers
- Electronics and sensor are back filled with medical-grade Argon
- Low noise, 16-bit operation and High tolerance sensor alignment and orthogonality
- 100% CNC Machined Sub-Assemblies with High Transmission camera windows (97%) and Custom window available with transmission below 200nm
Fused Silica glass is a notably higher quality of optical glass than most standard cameras use. It has very high purity and is one of the most transparent kinds of glass available. The optical and thermal qualities of Fused Silica glass are greatly benefited by it's extremely high purity. This is evidenced in its transmission and homogeneity, both of which exceed that of crystalline quartz while also bypassing the inherent issue of temperature instability that is inherent to the crystalline form. As it cools down, fused silica retains its shape with a high degree of accuracy. What that means is that its optical performance and focus are consistent and unchanging as temperature shifts occur over the day. Due to these features and more, Fused Silica Glass is the preferred optical glass of observatories and scientists!
This version of the CCD42 family of CCD sensors has full-frame architecture. Back illumination technology, in combination with extremely low noise amplifiers, makes the device well suited to the most demanding applications requiring a high dynamic range. To improve the sensitivity further, the CCD is manufactured without anti-blooming structures. There are two low noise amplifiers in the read out register, one at each end. Charge can be made to transfer through either or both amplifiers by making the appropriate R1 connections. The readout register has a gate controlled dump drain to allow fast dumping of unwanted data. The register is designed to accommodate four image pixels of charge and a summing well is provided capable of holding six image pixels of charge. The output amplifier has a feature to enable the response to be reduced, allowing the reading of such large charge packets.
