An objective lens holder is a vital component in optical systems, particularly in microscopes, telescopes, and other imaging instruments. It is designed to securely mount and position objective lenses, ensuring precise alignment and stability, which are crucial for achieving accurate and high-quality imaging results.

The primary function of an objective lens holder is to maintain the correct position and orientation of the objective lens relative to the rest of the optical system. This precise alignment is essential for focusing light correctly and obtaining clear, sharp images.
