• 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 plane-optically 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 also excellent for CCD camera technologies

This new generation of Baader CMOS filters features:

CMOS-optimized Baader Filters

• Increased contrast, matched for typical CMOS quantum efficiency and s/n ratio
• Reflex-Blockercoatings, for largest ever freedom from halos, even under most adverse conditions concerning aux-optics
• Identical filter thicknessto existing standards, with utmost care for parfocality
• Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim, to additionally eliminate any reflection due to light falling onto the edge of a filter
• Each filter coated individually, with sealed coating edge (NOT cut out of a larger plate with coatings left exposed,read more)
