50mm f/1.2 plano-convex lens

Product Description

Mounted High-Speed Plano-Convex Focusing Lens – 50mm Clear Aperture, ~60mm Focal Length (f/1.2)

This is a precision, fast-aperture plano-convex singlet lens professionally mounted in a robust black anodized aluminum cell. With an approximately 60mm focal length and a 50mm clear aperture, this f/1.2 lens provides powerful, concentrated focusing in a compact, ready-to-integrate package—ideal for demanding optical applications where light gathering and short focal length are critical.

Key Specifications:

• Clear Aperture: 50 mm (fully usable)

• Effective Focal Length (EFL): ~60 mm (confirmed via solar focus test)

• f/#: f/1.2 (extremely fast for its size)

• Lens Type: Plano-Convex Singlet (positive, converging)

• Material: High-Quality Optical Glass (likely BK7)

• Coating: Light AR coated or uncoated (minimal flare, high transmission)

• Mount: Threaded black anodized aluminum cell with retaining ring

• Orientation: For best performance, orient convex side toward collimated light

Why This Lens Is Exceptional:

• Fast f/1.2 Speed: Delivers intense focus and excellent light collection in a compact form.

• Professional Mount: The aluminum cell ensures secure handling, easy mounting, and protects the lens.

• Proven Performance: Focal length verified via simple solar focus test, confirming its specifications.

Applications:

• Laser Systems: Focusing or condensing beams from diodes, HeNe, or other visible/NIR lasers (use caution with high power densities).

• High-Magnification Optics: As an objective for short-range projection, magnifiers, or custom loupes.

• Optical Experiments: Ideal for bench-top setups in sensor illumination, beam shaping, or educational demonstrations.

• Imaging & Illumination: Component in microscope condensers, custom illuminators, or prototype optical devices.
