Filter size:None

Baader CMOS RGB-G (490 – 580 nm) Bandpass Filter, suitable from f/15 to f/1.8
Anti-reflection RGB filter (red/green/blue) with extremely high transmission of the respective color channel, thus simultaneously reducing stray light and reflections to an unprecedented level
Balanced RGB design allows subframes to be taken with the same exposure time – extremely important for automated imaging tasks
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

Create your own FILTER-LIBRARY:

This filter - except for size 100x100x3 mm - (in case of a filter set: each individual filter) comes in a Filterbox for all filters up to 50x50mm, stackable on all sides (#2459253 , € 7,- ) , to create your individual "filter-library", offering a secure place and immediate access for all Baader-filters. Putting this "library" into a carry bag will allow you to have all your loose filters stored safely in the field and be handy always.

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-Blocker^™ coatings, for largest ever freedom from halos, even under most adverse conditions concerning aux-optics

Identical filter thickness to 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)

Life-Coat™: evermore hard coatings to enable a non-aging coating for life – even in a most adverse environment

Don´t be misled.

These all new CMOS-optimized filters work magnificently with all existing digital camera technologies, be it CMOS or CCD. However – an owner of CCD-camera-technology will still find our previous, extremely affordable, narrowband filter technology to be fully apt for excellent imaging. But: "the Better always is enemy to the Good".
