Filter size:None

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

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".
