More about the product
These filters are intended for CCD applications.
Filter Specification:
- H-Alpha: CW 656nm, 12 or 7nm bandwidth
- O-III: CW: 500nm, 12 or 7nm bandwidth
- S-II: CW: 672nm, 12 or 7nm bandwidth
These filters are not suitable for solar observations!
Technical specifications
- Supporting glass of Schott
- Surface Quality 60/40 (corresponding to the EE kindness by American military standard MIL-O-13830)
- Fine optically polished, 1/4 wavefront
- min. 90% peak transmittance in the passband
- IR Blocking 700-1100nm off band
Coating properties:
High Homogeneous multilayer anti-reflection coating
The allowances are not cemented to the optical carrier, but applied Deposition (IBAD) method by electron beam evaporation and subsequent ion beam assisted.
This special process allows a high durability and scratch resistance, and high stability of the center wavelength (CWL) and prevents a temperature drift.
High transmission in the passband, high optical density in the stop band.
Filter version:
- Ultrathin filter mount for maximum passage: 26mm at the 1.25 "filters, 45mm at the 2" filters
- Precise CNC manufacturing
- Sandblasted
- Black anodized
- blackened to reflections
- Laser engraving - no fading of the label
