- Spherical aberration and coma are sufficiently corrected for visible to near-infrared monochromatic light, and collimated laser light can be focused to the spot diameter up to the diffraction limit.
- The wide AR coating of 495 to 570nm allows the use of lasers of various wavelengths within the band. In addition, since it transmits to some extent even at 632.8nm, a He-Ne guiding laser can be used.
- To take advantage of the excellent focusing performance obtained on the optical axis, it is recommended that the object side be moved.
- To protect the lens from laser-processed splashes, a replaceable protective glass is an option for the 10x objective lens. (The 20x objective lens originally has a protective glass attached to the product.)
