Azure Spy High-Precision Cemented Achromatic Doublet Lens, Ø52 mm, Focal Length 240 mm – Telescope Grade, Green Film Coated

The Azure Spy High-Precision Achromatic Doublet Lens is engineered for advanced optical applications requiring long focal length performance with exceptional clarity. Featuring a 52 mm clear aperture and an extended 240 mm focal length, this cemented doublet lens provides sharp, distortion-free images with excellent color correction across the visible spectrum.

Constructed from premium crown and flint optical glass, the doublet design effectively suppresses chromatic and spherical aberrations, making it ideal for high-magnification telescope systems and precision imaging instruments.

To maximize optical efficiency, the lens surfaces are treated with a green film anti-reflective coating, which enhances light transmission, reduces reflections, and ensures bright, high-contrast results even under demanding conditions.
