K9 Plano-concave Cylindrical Lens

The edge thickness and center thickness of the K9 glass flat concave cylindrical lens have strict standards to 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.
