特徴

• This is a product that lowers the surface quality by one rank from spherical achromatic lens (DLB).
• It can be used for optical systems that do not require high surface quality, such as telescope lenses and microscope imaging lenses.
• Specifications other than surface quality are almost the same as DLB.
• I recommend this lens unless you want to use it for high-precision experiments with lasers.
• Optimized to minimize aberration and reduce focal length deviation across the visible spectrum.
• It is corrected not only for aberrations of the on-axis object point, but also for off-axis coma and astigmatism.
• * Use an achromatic lens when you want to focus an image at infinity or when you want to use a point light source that is parallel to the image.
• Sufficient optical performance cannot be obtained when the camera is used for close-range imaging.
• * The chromatic lens has an orientation that allows parallel light to enter the lens.
• * This function allows parallel light to enter from the side of the face with a small radius of curvature (the face pointed to by the arrow).
• * When parallel light is incident from the opposite side, chromatic aberration and spherical aberration occur, and the condensing spot becomes larger.
