Alta® U Series: Best Warranty in the Business Alta cameras offer the best warranty in the business, and for good reason: Apogee's Alta Camera Series focuses on quality and reliability so you can focus on innovation and discovery. With a lifetime warranty against condensation in the inner chamber, and a two year parts and labor warranty, including the CCD, we have the best warranty in the industry. If you've got an out-of-box issue with one of our cameras, we're the only company that pays for shipping both ways. Why do we offer such an outstanding warranty? Because Alta cameras are rock solid from day one. So many improvements in such a small package: No external controllers, no plug-in cards, no frame grabbers. And with icron's USB extenders using Cat5 cable or fiber, the cameras can be up to 10 km from the host computer. USB 2.0 interface Resolution from 512 x 512 to more than 39 megapixels Wide variety of CCD architectures Single ActiveX driver and open source Linux driver for all models Free / open source driver for MicroManager / Image J software Dual 12/16-bit digitization to 32 Mbtye camera memory No plug in cards or external controllers Programmable cooling to 70C below ambient Precision Time Delayed Integration readout Programmable fan speed for zero vibration Runs from single 12V supply Alta U Series cameras are available with a wide variety of sensors, including: Back-illuminated sensors with very high quantum efficiency, some with sensitivity in the deep UV; Interline transfer sensors with fast electronic shuttering and inherent anti-blooming; front-illuminated CCDs with high sensitivity in the near-IR without etaloning. In general, the larger the pixel size, the higher the dynamic range. Smaller pixels (about 7 microns) are typically used for microscopy (U32; U2000; U4000); larger pixels and larger arrays are typically used for astronomy (U16M, U42, U47 back-illuminated; U3041, U9000, U6 front-illuminated).
