FilTRO OPTOLONG OIII-CCD 6.5nm 31x2mm sin celda [OPTOLONG]

0 de 5 (0 opiniones)

Technical Data



  • Schott substrate material

  • Thickness 2.0mm

  • Surface Quality: 60/40 (Refer to MIL-O-13830)

  • Fine-optically polished to ensure accurate 1/4 wavefront and <30 seconds parallelism over the both surfaces

  • 80% transmission at major OIII line 500nm

  • Infrared wavelength 700-1100nm cut-off

  • 0.1% transmission of off-band, specifically the major emission lines of artificial light pollution (i.e. Na 589nm, Hg 435nm and 578nm). Transmission of 0.1% is equivalent to OD3(Optical Density), and a high optical density value indicates very low transmission, and low optical density indicates high transmission.


Coating Parameter



  • Non-cementing optical substrate coating

  • Electron-beam gun evaporation with Ion-assisted deposition coating technology for durability and resistance to scratching, as well as stability on CWL(central wavelength) no deviation affected by temperature change

  • Planetary rotation system offers precision and homogeneity of coatings ensuring high value on transmission of pass-band and Optical density of off-band


Filter Cell



  • Ultra-thin filter cell minimize vignetting by maximize possible clear aperture (clear aperture is 26mm for 1.25”; 45mm for 2”)

  • Aerometal Material | Precise CNC Machining | Sand Blasting Process | Black Anodized Finish | Extinction Treatment to Prevent Reflection | Laser Engraving No Fading
