SPESIFIKASI :
- 80% transmission at passband / Precision off-band blocking
- Infrared wavelength 700-1100nm blocked
- 0.1% transmission of off-band, specifically the major emission lines of artificial light pollution (i.e. Na 589nm, Hg 435nm and 578nm)
- Suitable for use with mono CCD and CMOS cameras
- 1.25" / 2" mounted or 31mm / 36mm unmounted sizes.
- Supplied in a protective plastic case with EVA foam lining
- 2mm Thick Schott Glass
- Fine-optically polished on both sides - ensures accurate λ/4 wavefront and <30 seconds parallelism over the both surfaces
