The XRE Lens uses patent-pending technology and features electronic focus and configuration options for measuring a diverse array of AR, VR, and MR devices.
The lens can be paired with Radiant’s imaging colorimeters and photometers and software “to provide a complete automated visual inspection solution for XR display testing in R&D and production,” the company said.
The new lens follows on from Radiant’s AR/VR Lens, a XR display testing lens that was released in 2018.
“Fundamentally, replicating the human visual experience has continued to drive the optical design of XR test systems,” states Eric Eisenberg, optics development manager at Radiant. “But the diversity of XR devices and their measurement requirements continue to expand.”
According to Eisenberg this expansion in measurement requirements, which includes new display types, FOVs, resolutions, focal distances and form factors “can’t be addressed universally with a single optical solution.”
For this reason, he says, the new lens “can begin to address the diversity in XR optical designs and reduce the need for costly custom measurement equipment design cycles.”
According to Radiant, the XRE Lens is the first imaging metrology solution to offer electronic focus for in-headset XR display testing.
“Electronic focus is a huge advantage for XR testing,” said Eisenberg. “Analyses like through-focus MTF [modulation transfer function] are simply impossible with traditional manual lenses… With electronic focus, a through-focus MTF analysis can be fully automated to provide results in a matter of seconds.”
Radiant said they will be offering a live demonstration of the XRE Lens at the upcoming Display Week event in San Jose.
