An image intensifier is a device for increasing the intensity of available light in an optical system to allow use under low-light conditions, to facilitate visual imaging of low-light processes, to convert non-visible to a visible light source, or to provide increased light sensitivity for high-speed imaging applications.
Over the last 20 years - Resolve Optics has developed a reputation for successfully developing custom relay lenses for industrial partners looking to improve the efficiency of devices and instruments incorporating image intensifiers.
Rob Watkinson, Sales Manager said “A nice example of our capability in this area was when we were approached to design a custom relay lens to optimize the quality of image transfer from an intensifier to the image sensor in a high-speed range camera. Historically, most range camera designs have used off-the-shelf lenses placed back-to-back to transfer images from the intensifier to the image sensor. However, this approach produces a large amount of shading and image distortion. To overcome this inefficiency we designed a bespoke relay lens that was both compact and that eliminated the shading and distortion effects that degraded the quality of transferred images. The resultant novel f/2.8, 1 to 1.1-magnification relay lens has enabled our clients range camera to produce images with no visible distortion that are equally illuminated across the entire image area. The compact relay lens has also ensured optimal input into the microlenses on the range camera’s CCD image sensor”.
