Baader Clearglass Filter 2“ unmounted (ø 47,4mm) for FCCT – CMOS-optimized

Description

• Baader Premium grade impermeable 2" RGB-C Clearglass Filter without filter cell (Ø 47,4 mm), 2mm thickness
• The Baader clear glass filters are used to focus a camera when using very narrow band line filters (due to same mechanical thickness).
• Alternative function: e.g. our Protective Canon EOS T-Ring uses a clear glass filter for dust protection
• NO halos, NO reflections, NO ghosting
• Non-ageing sealed coating edges

• Optimized for modern CMOS cameras, but likewise excellent for older CCD camera technologies
• 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
• Reflex-Blocker™ coatings
• FWHM on each filter category carefully designed to allow for 1:1:1 exposures, matched for typical CMOS quantum efficiency and s/n ratio
• Blackened edges all around, with filter-lead-side-indicator in the form of a black frontside outer rim, to additionally eliminate any reflection due to light falling onto the edge of a filter with filter-lead-side-indicator in the form of a telescope-sided black outer rim
• Each filter coated individually, with sealed coating edge (NOT cut out of a larger plate with coatings left exposed read more)
• Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)
• Life-Coat™: evermore hard coatings to enable a non-aging coating for life – even in a most adverse environment

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.
