The IDAS Oxygen III filter is designed to isolate the OIII emission bands for best signal-to-noise performance for a wide range of telescope designs.
- 6.0 +/- 0.2nm (Measured value)
- 98% transmission rate (Measured value)
- Flat top, which maximizes the transmission even for fast optics
- Out-of-band blocking: 300-1300nm
- 2.5mm or 3.0mm thickness options
- 3 mount sizes - 48mm, 52mm & 50.8 (for filter wheels)
- Each filter is individually inspected for quality. The filter response is plotted and provided with each unit.
- Made in Japan
