Glass rod lens has a linear focus and a positive focal length. All kinds of aberration can be eliminated when used at the unit conjugate point. Choose your materials wisely, paying attention to texture, bubbles, impurities, and uniformity. For interference light, no scratches are produced during grinding. The two sides of the cylinder can be polished with an abrasive solution.
Applications:
