Sample quantities of OSVR custom dual asphere optics available for purchase

Allows developers to conveniently and inexpensively experiment with high-performance optics that are optimized for 5.5″ smartphone displays

COLUMBIA, MD (Aug 17, 2015) – Sensics, the leader in open-source virtual reality and founding contributor to OSVR, announced today that it has made developer samples of its dual-element custom asphere optics available for convenient purchase on eBay.

Designed by Sensics and used in the OSVR Hacker Developer Kit version 1.2, the optics have the following key characteristics:

  • Horizontal field of view: 90 degrees
  • Focal length: 35mm
  • TTL (distance from screen to the optical surface closest to the eye): 41mm
  • Total weight: 17.4 grams
  • Diameter: 32.4mm (lens 1), 43.2mm (lens 2)
  • Eye relief: 13mm
  • Eye box: 11mm
  • Ability to compensate for diopter by moving both elements closer or farther from the screen
  • -13.5% geometric distortion

The lenses are made of lightweight optical-grade plastic. One lens is molded from Zeonex F52R and the other is molded from Polystyrene. They have been also described on the RoadToVR blog: the dual-element optics of the OSVR HDK

A dual element design provides significantly better image than a typical single-element asphere. This can be seen in the image below. Geometric distortion is much lower. Focus is much clearer towards the edge of the image. Color aberration is minimized.

By making these lenses available for purchase by companies, hobbyists and researchers, Sensics is making it easy to determine if these or similar high-quality designs should be used in mass-production products.

Sample quantities of the lenses can now be purchased on eBay. Significant discounts are available for large quantities. Contact Sensics for details.

Additional off-the-shelf designs are available as well as the opportunity to create new custom designs to suit particular requirements.
