The Story

Alpine Astronomical FCUVIR-2 Overview

This 2" Eyepiece Filter Baader CMOS-Optimized UV/IR Bandpass L Filter, from Alpine Astronomical, reflects harmful thermal radiation in the infrared spectral range and provides 98% transmission over the entire visible spectrum from 420-685nm. This filter also prevents blurred star imaging with red-sensitive digital and CCD/CMOS cameras. It features a Reflex-Blocker hard coating, which has been planeoptically polished, and has Life-Coat sealed coating edges. It is equally suitable for modern CMOS sensors as well as for older CCD camera technologies.

  • Reflex-Blocker coatings offer largest ever freedom from halos, even under most adverse conditions concerning aux-optics
  • Provides increased contrast
  • Identical filter thickness to existing standards (2mm), with utmost care for parfocality
  • 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
  • Each filter coated individually, with sealed coating edge (not cut out of a larger plate with coatings left exposed)
  • Life-Coat: evermore hard coatings to enable a non-aging coating for life - even in a most adverse environment
