Excelitas Technologies Launches Cobra Eye Flat Field Eyepiece

Comfortable, Lightweight Eyepiece Offers High-Quality Performance for Thermal, Night Vision, Virtual Reality and Augmented Reality Systems

CobraEye – Lightweight Compact Eyepiece for Micro Displays

Excelitas Technologies® Corp., a leading industrial technology manufacturer focused on delivering innovative, market-driven photonic solutions, announces its new Cobra Eye™ flat-field eyepiece for integration into thermal, night vision, virtual reality and augmented reality systems. The Cobra Eye is compact and lightweight for user comfort, while enabling low distortion and a wide field of view (FOV).

The Cobra Eye eyepiece utilizes a combination of glass and plastic elements to meet a required weight of 60 g with a -6D to 2D dioptric adjustment. It has excellent correction of aberrations and color, which provides high resolution images across the FOV. This also makes the eyepiece ideal for monochrome and color display viewing applications. In addition, Cobra Eye avoids vignetting to ensure uniformity in brightness across the total FOV.

Cobra Eye is ITAR free. It offers 50 lp/mm resolution with just 4 percent distortion, and pixel pitch of 9.6um. Effective focal length is 22 mm, with full field view angle 40 degrees. Its maximum display size is 12.3 mm x 9.8 mm, with 15.7 mm diagonal (1280x1024) display (SXGA).

The new eyepiece operates at -40oC to +55oC and can be stored at -51oC to +71oC. It is configured to withstand vibration from 5 to 55 Hz and force up to 2.5 g, as well as mechanical shock of 40 g / 6 ms. Solar radiation specification is consistent with MIL-STD-810G, and sealing meets the IP68 standard.

Brad Tan, Excelitas’ Business Development Manager, said, “The Cobra Eye offers increased comfort and ease of use, enabling the latest technologies in high-performance vision systems such as augmented reality applications. This newest eyepiece design leverages Excelitas’ years of experience developing high-technology optics and meeting the highest performance needs of customers in a range of industries.”

The lightweight optic is configurable to customer needs. For more information, please visit https://www.excelitas.com/product/cobraeye-lightweight-compact-eyepiece-micro-displays.
