Updated October 2, 2020: Due to the ON Semi CCD retirement, some of our products have limited availability. We have the following available: STF-8300EN (monochrome, enhanced cooling): 7 units STF-8300CEN (one-shot color, enhanced cooling): 3 units STF-8050SC (sparse color): 1 unit STF-4070SC (sparse color): 7 units STF-4070C (one-shot color): 2 units Please note that other brands of CCD sensors are still available, including SONY and E2V. Our most popular Aluma CCD cameras are unaffected by the ON Semi sensor retirement. As they are being phased out, the replacement for STF is our new STC scientific CMOS series.
