Chroma Blue Filter
Visit Chroma blue filter is a high-precision optical filter designed for astronomical imaging, particularly suited to LRGB (Luminance, Red, Green, Blue) sets for astronomical photography.
Key features
- Spectral transmission :
- Focused on the visible blue spectrum, probably around 450-480 nm.
- Optimized for capturing details in the blue spectral range.
- Optical quality :
- Designed for f/4.0 or slower optical systems.
- Surface polished to an accuracy of λ/4.
- Multi-layer anti-reflective coatings to minimize halos and stray reflections.
Applications
- Color astrophotography :
- Integral part of LRGB assemblies.
- Captures spectral detail in the blue range.
- Astronomical imaging :
- Used with monochrome CCD/CMOS cameras.
- Ideal for imaging celestial objects with significant blue components.
Available formats
- Mounted: 1.25", 2".
- Unmounted: Customized formats available
Conclusion
Visit Chroma Blue filter is an essential tool for astrophotographers seeking precise, detailed color reproduction in astronomical imagery.
