The Antlia LRGBR+ Dark series filters are designed with a full spectrum curve from 390nm to 1000nm, making it sensitive to both UV and IR light for high signal-to-noise ratio and contrast imaging in deep sky full-spectrum photography.
Considering the high quantum efficiency (QE) of the cameras in the near-infrared bands, Antlia incorporates a Red+ 700-1000nm filter into LRGB dark filter series (sold separately) to capture valuable signals that cannot be detected by regular LRGB filters.
In post-processing, combine the R and R+ channels to create a new R channel. The remaining steps for processing are identical to those used as regular LRGB filters.
Applications and Performance:
- Full spectrum design enhances the sensitivity of imaging to both UV and IR light.
- More infrared signal to be found by combining Red+ filter with LRGB Dark filters;
- Out of band blocking specification is designed to OD4.5 (0.005%) to block interference from other wavelengths and minimize halos around bright stars;
- Identical filter thickness to existing standards and double-sided fine polishing , with utmost care for parfocality
- All Antlia filters are coated to the edge of the substrate and unmounted narrowband filters are edge blackened to eliminate internal reflections from stray light
- Filters are resistant to scratches
- Warranty: 3-years against delamination.
Technical Specifications:
Red+ filter:
- Transmission Range: 700-1000nm
- Peak Transmission: 95%
- Substrate: HWB
- Blocking: ≥OD4.5 (0.005%)
- Filter Thickness: 2mm+/-0.05mm
Filter Ring:
- None. 36mm round diameter, Unmounted
Not Recommended:
- Solar Observing and imaging
- Night visual observation
DO NOT LOOK AT THE SUN WITH ANTLIA FILTERS. Serious eye damage will result if you fail to observe the warning.
