Azure Spy High-Precision Cemented Achromatic Doublet Lens, Ø93 mm, Focal Length 1000 mm – Telescope Grade, Green Film Coated

The Azure Spy High-Precision Achromatic Doublet Lens is designed for serious astronomers and research-grade optical applications, combining a large 93 mm aperture with an extended 1000 mm focal length to deliver exceptional resolution, brightness, and true-color accuracy. This cemented doublet lens provides powerful light-gathering capability, razor-sharp detail, and excellent chromatic aberration correction, making it ideal for high-magnification and long-range observations.

Manufactured from premium crown and flint optical glass, the achromatic doublet construction minimizes chromatic and spherical aberrations, ensuring high-contrast, distortion-free images even under demanding observing conditions. The long focal length and wide aperture make this lens perfect for planetary and lunar observation, deep-sky astronomy, astrophotography, and precision research instruments.

To further enhance performance, the optical surfaces are treated with an advanced green film anti-reflective coating, which significantly boosts light transmission, reduces reflections, and provides bright, high-contrast imaging across the visible spectrum.
