Important Note About Torn Baader Filter Seals:
Recently, Baader started applying a new filter label on many filters that goes over the edge of the case and also acts as a seal. Unfortunately, these labels rip far too easily during transport, giving the false appearance that the filter case has been previously opened. Many filters we now get from Baader arrive like the ones shown in the photos below, and many others will rip en route from us to you. Rest assured that ALL filters we ship to you are brand new and unopened as received from Baader, whether the seal is intact or partially/completely ripped.

Baader has agreed to revert to their old design of 2-piece labels, but until they use up their current labels, we will continue to have this problem for a while and you might also get a mix of different filter label types. Thank you for your understanding.
New CMOS-optimized L-RGB filters from Baader Planetarium with Reflex-Blocker™ and Life-Coat™. Sold individually and in sets.
Baader CMOS UV/IR Bandpass / L-Filter
- UV/IR Cut (420 – 685 nm)
- 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
Baader CMOS RGB Bandpass Filters
- RGB-R (595 – 690 nm) red filter
- RGB-G (490 – 580 nm) green filter
- RGB-B (400 – 510 nm) blue filter
The new generation of Baader CMOS-optimized filters feature:
- 1¼" x 2 mm Baader L-RGB Bandpass Filter Set, suitable from f/15 to f/1.8 – with 1¼" (28.5 mm) filter thread
- 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
- 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)
- Life-Coat™: evermore hard coatings to enable a non-aging coating for life – even in a most adverse environment
Specifications
- Filter thickness (without cell): 2mm
- AR Coating: Reflex-Blocker™ hard coated, planeoptically polished
- Special features: CMOS-optimized with Life-Coat™
- Filter mount choice: 1.25" round mounted in LPFC 6mm cell
- Type of filter: Bandpass
Life-Coat™: Limited-Lifetime-Warranty for CMOS-optimized Baader filters
A Baader Planetarium exclusive. Filters incorporating Baader Planetarium’s Life-Coat™ technology are so durable that Baader Planetarium warrants the coatings for the life of the filter. Baader Planetarium has developed Life-Coat™ using materials and processes that result in coatings which will not degrade or fail for a lifetime. Life-Coat™ coatings resist moisture, temperature extremes, and are hardened to withstand normal cleanings.
Baader Planetarium guarantees their Life-Coat™ coatings will not peel, flake or physically degrade and will withstand repeated cleaning with fine optical cleaning equipment. The Limited Lifetime Warranty applies to the original purchaser and does not cover failure from mis-use, physical damage through improper handling, or improper cleaning.
