S ome customers require a complete absence of vibration during an exposure. The Alta systems have been designed for complete control of the cooling fans. The fans may be turned off, or run at a much slower speed to maintain adequate cooling with no vibration. For applications where vibration is not an issue, the fan speed may be maximized for greatest cooling. The fans used in the Alta system were selected for minimum
vibration.
The Apogee cooling system has long been one of the most advanced in the industry. The Alta control system has been expanded to 12 bits, allowing a temperature control range of 213K to 313K (-60 to +40 C) with 0.024 degree resolution. Sensors have been added to monitor the heat sink temperature. A power indicator has been added to give the user an idea of how much drive is being given to the CCD cooler. The automatic back-off function is now handled by the fi rmware and driver. If the system cannot reach the desired temperature, the system automatically backs off to a point where regulation can be maintained, 2 degrees above the maximum temperature reached. The new set point is given to the user. Cooling deltas of 40-60C (depending on sensor area) are typical with simple air cooling.Apogee now offers liquid recirculation backs for Alta cameras. For customers desiring greater temperature performance where the camera housing will not go below the dew point, specifying liquid recirculation will assure a lower dark count than is possible with forced air cooling. The Alta E Series cameras fi rst read the entire image into the camera head memory, and then transfer the image to the host computer at a maximum of 200 kpixels/second. An Alta U47 camera with 1 megapixel reads the entire image to the computer in about 1.5 seconds. An E47 reads the image to the camera memory in 1.5 seconds, but then requires an additional 5 seconds to transfer the image to the host computer. The Alta systems are designed to be very compact. At 6x6 and only 2.2 thick with no external electronics, the Alta system packs a lot of power into a small package. The Alta systems are more than a kilogram lighter than than their predecessor. Alta cameras with small format CCDs have a 0.69 (17.5 mm) C-mount back focal distance for direct interface to microscopes and C-mount lenses. Medium format sensors use the D2 housing with 2 thread. Large format sensors use the D7 housing with a 2.5 thread. Back focal distance for the D2 and D7 housing is approximately 1.04 (26.4 mm). All cameras have a bolt circle with metric threads for adaptation to a wide variety of fl anges. Lower profi le housings are available for all Alta models to achieve <0.5 (<12.7mm) back focal distances without internal shutters.

The Alta E Series cameras each have a unique MAC address so they can be plugged directly into the internet for remote operation. We provide MaxIm software for remote control of the camera. They cannot be controlled through your browser. Because the camera has slave serial, I2C, and auxiliary fi lter wheel support, an entire setup can be controlled from behind a single camera interface. For WAN or WWW connections, a full TCP/IP protocol gives safe data transfers at slower speeds. A special bi-directional digital interface with 6 I/O lines can also be used to interface to other system components. High level shutter signals, as well as digital strobes and triggers, are available. TWO TWO SERIAL COM PORTS & GENERAL I/O PORT SERIAL COM PORTS & GENERAL I/O PORT
Our general purpose I/O port can tell you when the shutter is open, or can be used for a wide variety of external trigger inputs, including line-by-line control of TDI shifts. Our two serial COM ports can control periph- erals like fi lter wheels through the cameras control cable (USB2 or ethernet). Alta cameras use three shutter types, depending on the aperture. Apogee shutters use lower voltage coils then those listed as standard by the shutter manufacturers, roughly 1/2 of the standard voltage requirement. The lower voltages extend the lifetimes of the shutters. D1 housing, small format sensors: Vincent Uniblitz 25mm Shutter D2 housing, medium format sensors: Melles Griot 43mm Shutter D7 housing, large format sensors: Melles Griot 63.5mm ShutterFull frame CCDs typically require an electromechanical shutter unless the light source is gated in some other way. Otherwise light falling on the sensor during the readout process corrupts the image. Interline CCDs shift the charge from the photodiode section of each pixel to the masked storage diode. For low light applications, the mask is suffi ciently opaque to prevent smearing. However, in high light applications, interline CCDs require electromechanical shutters to prevent smearing during readout. Apogee Instruments uses the fi nest shutters available for our cameras from Vincent and Melles Griot. These shutters have been carefully integrated into our camera heads with minimum impact on back focal distance and camera size. These shutters have a huge advantage of simple rotating blade shutters in terms of light blockage and minimum exposure time. Professional grade details like magnesium- fl ouride coated fused silica windows. Apogee also offers custom windows, including wedge windows and customer supplied optics.

Alta camera systems include a 12V international power supply (100V-240V input), but can be operated from a clean 12V source. LIQUID LIQUID CIRCULATION CIRCULATION CABLE CABLE LENGTH LENGTH
Ethernet cabling can go to 100m. USB2 cables are limited to 5m between hubs, with up to 5 hubs, for a total of 30m. However, there are USB1 and USB2 extenders available for operation up to 10 km. The USB1 extenders slow the transfer to a maximum of 500 kpixels per seoond, but this rate is still a far higher throughput than the E Series systems. USB2 extenders are available using Cat5 cable or fi ber optic cable. Apogee offers Alta and Ascent liquid recirculation backs for customers wanting to remove heat dissipation from the area of the camera; wanting to house the camera inside an enclosure; or wanting supplemental cooling. The limitation: the temperature of the recirculating liquid must not go below the dew point.
