Filtro RGB-B CMOS 50,4mm

Anti-reflection RGB filter (red/green/blue) with extremely high transmission of the respective color channel, which simultaneously reduces scattered light and reflections to an unprecedented level.

A balanced RGB design allows shots to be taken with the same exposure time - extremely important for automated continuous shooting.

The CMOS-optimized filters from Baader are characterized by:

• increased contrast
• narrower full widths at half maximum (FWHM)
• Reflex-Blocker™ coatings for the greatest possible insensitivity to retro-reflection from the nearest auxiliary optics, even under the most adverse conditions
• FWHM carefully designed for each filter category to enable 1:1:1 exposures, matched to typical CMOS quantum efficiency and signal-to-noise ratio
• Identical filter thickness to existing standards, with the greatest care regarding homofocality
• Blackened edges all around, with filter front indicator in the form of a black outer edge on the front to additionally avoid any reflection from light falling on the filter edge
• each filter individually optically polished and coated, with sealed coating edge (NOT cut out of a larger plate with the coating edges exposed as a result)
• Life-Coat™ : even harder coatings to enable an aging-resistant coating over an unlimited service life - even in the most adverse environments

This new generation of CMOS-optimized filters is designed to become the new standard in amateur astronomy.
