K9 Plano-convex Cylindrical Lens

There are strict standards for the edge thickness and center thickness of K9 glass cylindrical lenses, which can ensure minimal wavefront distortion. In addition, it also has good thermal stability and can be used in high-temperature environments, suitable for single axis internal focusing or expanding light. It can be coated with reflective film, anti reflective film, filter film, spectroscopic film, polarizing film, and metallization film systems.
