Biconvex Lenses

Positive Focal Length: The Biconvex Lens has a positive focal length, allowing it to effectively converge collimated light.

Versatile Applications: Its uses extend to modulation and focusing of laser beams, as well as imaging instruments, demonstrating its versatility in optical applications.

Optimal Performance in Specific Scenarios: When the absolute finite conjugate ratio is close to 1:1, Biconvex Lenses are particularly recommended as they help minimize spherical aberration, coma, and distortion.

Customizable Options: Kingwin Optics offers tailored specifications for diameters, focal lengths, and f/numbers, along with custom coating options to suit specific application requirements.

High Precision: The lens surface irregularities can be manufactured to the conventional λ/4 or λ/8, depending on the precision needed for the application.

Applications: Laser Systems, Imaging Technology, Optical Instrumentation, etc.
