• New CMOS-optimized UV/IR-Cut / L-Filter filters from Baader Planetarium with Reflex-Blocker™ and Life-Coat™

  
  

  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

  
  

  The new generation of Baader CMOS-optimized filters features:

  • 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 is coated individually, with a sealed coating edge (NOT cut out of a larger plate with coatings left exposed read more)
  • Reflex-Blocker™ hard coated and plane optically 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

  
  

  Transmission Range

  • L (420 – 685 nm)
  • R (595 – 690 nm)
  • G (490 – 580 nm)
  • B (400 – 510 nm)

  
  

  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.
