Antlia LRGB-V Pro series filters - 36mm Unmounted

Antlia LRGB-V Pro series filters

The Antlia LRGB-V Pro series filters are designed for monochrome cameras that use both CCD and CMOS sensors. Suitable sensors include KAF/KAI sensors, Sony IMX sensors, GSENSE and other sensor manufacturers. The LRGB-V Pro set is designed to approximately equalize the RGB response from the flux of red-sensitive CCD detectors. The result is that you achieve 1:1:1 equalized RGB exposures with the benefit of simplified post processing and reduced imaging time. New LRGB-V Pro series filters feature a carefully designed spectral gap between the green and red channels to minimize the effect of light pollution and to provide high transmittance of useful frequencies. The filters’ design maximizes the capture of details from fainter galaxies and nebulae emissions. The LRGB-V Pro series filters guarantee the high transmission of the OIII band in both the B and G filters (OIII signal >95% in blue and green). The bandwidth of the B channel is narrowed for the purpose of improving the blue channel overflow (haloing) around the star due to B channel overexposure. Antlia LRGB-V Pro series filters block the emission line around 589nm by the design of wide gap between G and R filters, which suppresses much of the light pollution from high pressure sodium and mercury street lamps and results in a more natural color balance. The uniformity in substrate thickness delivers good parfocal performance across all Antlia filters.

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.
