MENISCUS LENSES
| POSITIVE MENISCUS, NEGATIVE MENISCUS Positive meniscus lenses are designed to minimize spherical aberration and are usually used in small fnumber applications (f#〈2.5). For 2.5 f#〈10, meniscus lenses can also improve image quality and reduce spot size. Negative Meniscus lenses are offered as an alternative to other negative lenses and are particularly appropriate for the high index IR materials. They are commonly used in beam expanding applications where minimal spherical aberration is desired. MOS Meniscus Lenses are designed to customers requirements. Both sides can be coated with a MOS high efficiency narrowband, anti-reflective coating |
