Custom Bi-Convex Spherical Lens with AR Coating
What is a Bi-Convex Spherical Lens?
A bi-convex spherical lens is a symmetrical convex lens.
Both of its surfaces are outwardly convex spherical surfaces, and usually have the same curvature radius.
This symmetrical structure gives it unique optical properties in the optical path。
Because it can converge parallel incident light to the symmetrical focal points on both sides of the lens, and also convert the divergent light emitted by a point source into parallel light.
Advantages of the Bi-Convex Spherical Lens
- Well concentrating and collimating performance
The convex surfaces on both sides of the double convex spherical lens can jointly act on the incident light.
- Symmetrical structure suits symmetrical optical path
The symmetrical double convex structure enables it to perform best in the symmetrical object-image optical path.
- Wide applicable wavelength range and strong adaptability
By selecting different base materials, the double convex spherical lens can be used from ultraviolet to infrared.
- Mature process and controllable cost
The processing technology of the double convex spherical lens is very mature, with stable spherical grinding and polishing techniques and high batch production efficiency.
Applications of the Bi-Convex Spherical Lens:
Imaging equipment:
- Microscope: The lens is the core component of the objective lens or eyepiece
- Telescope: Also, people often ust it to converge the light from distant celestial bodies, enhancing the brightness and clarity of observations
- Camera and video camera: In the lens group, they undertake the functions of focusing and imaging
Laser technology:
- Laser focusing: Laser cutting, laser welding, laser marking equipment
Optical communication and sensing:
