25 mm biconvex F45 mm lens for VR optics and projection

This 25 mm biconvex lens with a focal length of 45 mm is an excellent choice for VR headsets, optical experiments and DIY projects. The lens is made from optical plastic with high light transmission and is designed to provide a sharp and magnified image. The biconvex shape collects light into a focal point, making it suitable for both magnification and projection.

The lens can be used in VR headsets where it magnifies the image from a small display, allowing the eye to perceive a much larger image at a comfortable viewing distance. It is also suitable for experiments with LED matrices, small LCD displays and other light sources.

For projection, the object is placed slightly beyond the focal length to create a sharp image on a wall or projection screen. The closer the object is to the focal length, the larger the projected image becomes. Moving the object farther away reduces magnification and shortens the projection distance.

The lens is also well suited for education, laboratories, hobby electronics and prototype development where light refraction and optical principles are demonstrated or tested.
