For sale is a 2-inch Baader UV/IR-Cut / L-Filter – CMOS-optimized filter. I used it when doing one shot color imaging, but since transitioning to mono, this is no longer required. First owner, excellent condition, like new. From the few UV/IR-Cut filters I tested, this is the best one, no halos, no loss of contrast.
Overview:
- Baader CMOS UV/IR-Cut (420 – 685 nm) Bandpass Filter, suitable from f/15 to f/1.8.
- Reflects harmful thermal radiation in the infrared spectral range.
- Provides 98% transmission over the entire visible spectrum from 420 - 685 nm.
- Prevents blurred star imaging with red-sensitive digital and CCD/CMOS cameras.
- Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™).
- Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim.
- Optimized for modern CMOS cameras, but likewise excellent for CCD camera technologies.
