Chroma Clair filter - 2″ mounted

Chroma Clear filter

Visit Chroma Clair filter is designed for astronomical imaging, capturing the entire light spectrum without altering the incoming light. Here are its main features:

Key features

• Spectral transmission Average transmission greater than or equal to 97 % over a wide range from 380 nm to 1000 nm.
• Main objective Designed to protect CCD/CMOS camera sensors without affecting incoming light.
• Specific applications :
  • Observation or imaging where the aim is to capture all available light without filtering.
  • Can be used as an optical protection filter to prevent dust or scratches on sensors.
• Technical specifications :
  • No UV- or IR-blocking coatings, which can lead to chromatic aberration in some optical systems.
  • Compatible with high-speed systems (f/4.0 or less).

Chroma Luminance filter (L)

Visit Chroma Luminance filter is designed specifically for capturing luminance detail in astronomical imaging, while offering optimum performance for creating balanced color images. Key features include:

Key features

• Spectral transmission Effective UV blocking (700 nm), allowing only visible light to pass through.
• Main objective Capture luminance data to improve sharpness and contrast in LRGB imaging.
• Specific applications :
  • Advanced astrophotography with monochrome cameras.
  • Reduces optical artifacts caused by UV and IR, particularly useful in refractive systems.
• Technical specifications :
  • Parfocal with other LRGB filters.
  • Anti-halos design thanks to multi-layer coatings.
