New varieties of wood-based panels are increasing, and their classification methods are constantly changing. The commonly used classification methods are as follows:

1 according to the tree species used

There are softwood plywood, hardwood plywood, etc.;

2 by nature of use

There are outdoor plywood, indoor plywood, structural plywood, decorative plywood, etc.;

3 according to the molding process

There are wet, dry and semi-dry fiberboards;

4 according to the pressure method

There are flat pressing, extrusion, rolling particle board, etc.;

5 by product density

Low-density, medium-density, high-density particleboard; soft, medium-density, high-density (hard) fiberboard;

6 according to the glue material

There are organic glued wood-based panels, inorganic glued wood-based panels, and the like.

Mini Ball Lens

Spherical ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and ease the sensitivity of translational alignment. However, smaller spheres fit into smaller packages. The addition of a broadband MgF2 antireflection coating results in a highly efficient lens due to the high refractive index of the glass. Coupling efficiency is generally >90% due to the simplicity of these lenses.
