Baader UV IR-Cut L-Filter – CMOS-optimized

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 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
