Introduction

John M Palmer is a notable inventor based in Clwyd, GB. He has made significant contributions to the field of optical systems, holding a total of three patents. His work focuses on enhancing the performance and efficiency of optical devices.

Latest Patents

One of his latest patents is for optical beam expanders with materials chosen to effect athermalization. This invention features an optical substantially afocal beam expander that includes a negative lens element spaced from a positive lens element. The lens elements are made from different materials, each with distinct coefficients of refractive index change concerning temperature. This design allows the temperature change effects on one element to be partially compensated by the other, resulting in a substantially athermalized beam expander.

Another significant patent is for infra-red optical systems. This invention involves an infra-red optical system, such as an afocal telescope, which incorporates a beam-splitter plate positioned in a beam position with one numerical aperture value. The system also includes a single compensating plate located in a different beam position, tilted to compensate for aberrations introduced by the tilted beam-splitter plate. The design ensures that both plates are tilted about respective axes orthogonal to the optical axis, enhancing the overall optical performance.
