IDAS NBZ Filters

IDAS NBZ Filters are designed to enhance the contrast of Hα and OIII emission nebula, yet accommodate the filter spectral shift when used with modern fast optical systems. This dual-band filter is ideal for one-shot color cameras as well as mono-color astronomical cameras.

Features Include

• Ideal flat-top Band-pass
• Excellent in-band transmission
• Off-center Band-pass accommodates off-axis rays for fast optics (up to F2)
• Steep Band-pass edges minimize internal reflections
• No IR blocker required
• Available in 52mm and 48mm sizes
• 2.5mm thickness (Par focal with other IDAS LPS filters)
• IDAS-proprietary IGAD/MBT/UFP quality
• Made in Japan
