Περιγραφή
The Antlia V-Series Luminance filter is available separately for use as a high-quality UV/IR filter.
Highlight of LRGB-V Pro series set
1. Premium coating technology and finely polished substrate Our quality selection processes are optimized to ensure highly homogeneous glass-substrates. Our application of advanced optical coating technology and double-sided precision polishing achieves both consistent parfocal and optical performance across all filters. 2. Maximized colour balance and contrast for each of the three RGB channels and excellent S/N performance Dozens of coating layers are deposited on both sides of the glass substrate that enables LRGB-V Pro filters to achieve a high SNR. The Anti reflection coatings and carefully designed spectral gaps minimize unwanted light scatter and maximize useful signal data for each filter channel.
3. Tighter star profiles and halo reduction The cut-off rate of LRGB-V Pro series set is designed in high level to minimize halos around brighter stars and reduce star bloat. Our careful design of the blue channel transmission characteristics targets the problem of blue star bloating.
Application and Performance:
- Designed for monochrome CCD and CMOS cameras
- Great imaging colors for celestial objects, galaxies, star clusters and nebulae
- AR anti-reflection film design for secondary reflection and star halo reduction
- R-Filter provides maximum transmission of H-alpha and S II emission
- B/G overlap doubles the energy in the OIII line
- Balanced RGB-design offer 1:1:1 exposure times for most telescope optical systems
- All Antlia LRGB-V Pro filters are edge blackened to eliminate internal reflections from stray light
- The substrate thickness of each of the four LRGB filers is maintained to tight tolerances
- Not recommended for Solar observing and imaging
- Not recommended for visual observation
With a luminance filter, you can take monochrome images across the entire visible spectrum even when using refractive optical elements, thereby improving the detail reproduction of RGB images.
