30-Day Money Back Guarantee 1 Year Extended Warranty

The F77 represents the next step in the evolution of the Alta line of cameras with faster readout speeds. The Alta F77 has a back-illuminated large pixel format CCD with deep dynamic range. The F77 is well suited to spectroscopy, TDI imaging and telescopes with long focal lengths. The standard midband coating (F77-MB) has the highest peak in the visible; the optional UV-enhanced version (F77-UV) has the highest QE in the UV. All Alta systems are backed by a 2 year warranty on the camera and lifetime warranty on the CCD chamber integrity.
