Azure Spy High-Precision Cemented Achromatic Doublet Lens, Ø80 mm, Focal Length 900 mm – Telescope Grade, Green Film Coated

The Azure Spy High-Precision Achromatic Doublet Lens is crafted for telescope-grade performance and advanced optical applications, offering exceptional clarity, resolution, and accurate color correction. With a large 80 mm clear aperture and a long 900 mm focal length, this cemented doublet delivers excellent light-gathering power, sharp resolution, and minimized chromatic aberration, making it highly effective for high-magnification astronomy and research-grade imaging.

Engineered from premium crown and flint optical glass, the precision-bonded doublet design significantly reduces spherical and chromatic aberrations, ensuring high-contrast, distortion-free imaging. The long focal length combined with a wide aperture makes this lens ideal for planetary observation, deep-sky viewing, astrophotography, and advanced optical instruments.

The optical surfaces are treated with a green film anti-reflective coating, which enhances light transmission, reduces reflections, and delivers brighter, sharper, and higher-contrast images under both daylight and low-light astronomical conditions.
