Introduction:
- 6mm F1.2 large aperture, improving starlight collection efficiency; Compared to the previous generation F2.0 lens, the F1.2 large aperture has stronger light collection capability, making it suitable for short exposure shooting and real-time observation of the Milky Way.
- Adopting an absorption type deep red filter to reduce the band shift caused by oblique incident light, making the color expression of the large field of view image more uniform.
- Blue green light transmittance <0.001%, cutoff wavelength of 702nm, infrared transmittance >96%, while suppressing light pollution, retaining more deep red and near-infrared starlight signals.
- Preferred 700nm wavelength band, balancing starlight and light damage suppression; Urban light pollution is not only caused by artificial lighting, but also by factors such as natural glare. LP700 retains more deep red and near-infrared starlight signals, while balancing light pollution suppression and imaging signal-to-noise ratio.
