IDAS UV/IR blocking filters are designed for use with lens optical systems, which are typically not corrected for the UV and IR bands. These filters feature sharp cut-offs, minimized in-band reflections, and incorporate IDAS MBT, UFP, and IGAD technologies to insure undegraded and extremely durable optical performance.
IDAS UV/IR Blocking Filter
IDAS Filter Technology...
"A chain is only as good as its weakest link." This well-known truth applies to many "chains", including the optical chain, which includes a telescope, eyepiece, and filter. With this important concept in mind, it is good to know that IDAS filters are manufactured using unique technologies that result in quality that meets or exceeds that of the rest of your optical chain.
IGAD, or Ion-Gun Assist Deposition...
This coating technology was originally developed for the optical communications field where long-term stability (>25 years) over harsh field conditions is required. IDAS is the first manufacturer to apply this technology to astronomical filters, including the UV/IR. This results in superior filters with robust coatings and long-term spectral stability even under temperature and humidity extremes. This stability is especially important for bandpass curves with steep slopes such as H-alpha, LPS filters, and other narrow bandpass filters. IGAD filters virtually eliminate bandpass shifts from the +/-3 or 4nm typical of standard coating filters.
MBT, or Multi Band-Pass Technology...
This technology was originally developed for biomedical microscopes, but improved by IDAS by combining it IGAD hard-coating technology. The excellent filter responses possible with Multi Band-Pass Technology allows IDAS to create very complicated filters for astronomical use such as the unique LPS filter.
UFP, or Ultra Fine Polish...
IDAS filters are polished twice as long as is typical for optical glass. In combination with the use of high-quality substrate glass, no scratches, bubbles, or other defects are visible even under microscopic inspection.
