61-6956-48 Reasonable Achromatic Lens Focal Length 119.8mm S-DLB-25-120PM
Features
- 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.
