SKU
SLB-N-IR1
These simple negative lenses have many uses. Alone they form a virtual image of a distant object
or collimated light source. Used in combination with other optics they reduce the power of the
system. Sharp edges which are common in negative lenses are removed by beveling in order to
reduce the likelihood of chipping.

These simple negative lenses have many uses. Alone they form a virtual image of a distant object
or collimated light source. Used in combination with other optics they reduce the power of the
system. Sharp edges which are common in negative lenses are removed by beveling in order to
reduce the likelihood of chipping.
