Red Chroma filter
Visit Chroma red filter is a high-quality filter designed for color astronomical imaging, used in combination with the green and blue filters in LRGB sets. It is optimized to capture the red light of the visible spectrum while blocking unwanted wavelengths, guaranteeing precise, artifact-free images.
Key features
- Spectral transmission :
- Focusing on the visible red spectrum.
- High transmission to maximize detail capture in this wavelength range.
- Optical quality :
- Surface polished to an accuracy of λ/4.
- Multi-layer anti-reflective coatings to minimize halos and stray reflections.
- Parfocality with Chroma's other LRGB filters, facilitating their use in filter wheels.
- Available formats :
- Mounted: 1.25", 2".
- Unmounted: Customized formats (31 mm, 36 mm, etc.).
- Compatibility :
- Optimized for optical systems with focal ratios up to f/4.0 or less.
- Works perfectly with monochrome CCD and CMOS cameras.
Applications
- Color imaging (LRGB) :
- Used to capture the red component in RGB sets, producing balanced, realistic color images.
- Advanced astrophotography :
- Ideal for photographing objects rich in red light, such as certain red giant stars or H-alpha regions, when combined with other filters.
- Scientific observation :
- Enables detailed analysis of the spectral properties of celestial objects in the red range of the spectrum.
Technical advantages
- Effective blocking of unwanted wavelengths :
- Reduces light interference from artificial or natural sources outside the red spectrum.
- Outstanding durability :
- Made from robust materials resistant to extreme observation conditions.
- Anti-halos design :
- Eliminates halos around bright stars for optimal image sharpness.
Conclusion
Visit Chroma Red filter is an essential component of LRGB packages for astronomical imaging. Its optical precision and high transmission make it possible to capture rich, precise detail in the red spectrum, while ensuring perfect compatibility with other Chroma filters. An essential choice for astrophotographers seeking to produce high-quality color images.
