The Antlia LRGB Dark series filters are designed with a full spectrum curve from 390nm to 710nm, making it sensitive to both UV and IR light for high signal-to-noise ratio and contrast imaging in deep sky full-spectrum photography.
The LRGB dark series filters are made of quartz glass, which has exceptional thermal and mechanical properties due to its ultra-low thermal expansion coefficient. These filters offer remarkable durability for imaging and research in the most challenging environmental conditions.
Considering the high quantum efficiency (QE) of the cameras in the near-infrared bands, Antlia incorporates a Red+700-1000nm filter (sold separately) into LRGB dark series 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.
The LRGB Dark series filters are best paired with Antlia SHO 2.8nm and 2.5nm Ultra Narrowband filters, as they share the same quartz substrate and refractive index, resulting in better parfocality.
Applications and Performance:
- Full spectrum design enhances the sensitivity of imaging to both UV and IR light.
- High transmittance B filter≥95%, L-R-G filter≥97%, this ensures that there is almost no loss in image signal, maximizing contrast;
- Made of quartz glass, excellent durability and thermal stability, as well as better fracture and scratch resistance, improved coating resilience to cleaning;
- More infrared signal to be found by combining Red+ filter (sold separately);
- 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:
- Transmission Range:
- Luminance UV/IR: 390nm-710nm
- Red: 595-705nm
- Green: 495-600nm
- Blue: 400-505nm
- Peak Transmission:
- Luminance UV/IR, Red, Green: 97%
- Blue: 95%
- Substrate:
- Quartz Glass
- Blocking: ≥OD4.5 (0.005%)
- Filter Thickness: 2mm+/-0.05mm
Filter Ring:
- 2" Mounted (M48.5x0.75 thread)
- Ultra-thin filter cell to minimize vignetting by maximizing possible clear aperture
- Black Anodized Finish
- Laser Engraving, No Fading
Not Recommended:
- Solar 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.
Includes:
- Set includes four filters: Luminance (IR/UV-blocked colorless), Red, Green, and Blue
