Energy protection filters are long-pass filters that block short-wave light. A coating blocks IR. This means that the filters of an H-alpha telescope are only exposed to red light.

- Thickness (mm): 12mm
- Surface shape: L/4
- Centre wavelength (nm): 656.28
- Bandwidth (nm): 60
- Peak transmittance (%): 95%
- Cut-off range (nm): 200nm-1100nm
