Non-browning lenses

Share this on social media:

Resolve Optics has expanded its range of fixed focus non-browning lenses for close-up inspection tasks in high radiation environments.

Designed to provide uncompromised performance on 2/3-inch cameras the new 6mm focal length Model 214 and 9mm focal length Model 286 lenses deliver high image resolution (f2) and minimal geometric distortion from 400 - 750 nm.

Manufactured to the highest quality standards from cerium doped glass, Model 214 and 286 lenses are able to withstand radiation exposure of up to 100 kGy (100,000,000 rads) and temperatures up to 55 degrees centigrade without discoloration.

Most non-browning glass lenses are yellow tinted which unfortunately gives images acquired by colour CMOS cameras a yellow appearance. To provide a solution for this problem, Resolve Optics developed the Model 313 - a 25mm focal length (f1.4) fixed focus non-browning lens. Using specially selected glasses with the least amount of yellow tint, so that the image would be as natural as possible, the Model 313 still retains non-browning performance in environments subject to radiation.

Resolve Optics has also developed a specialist lens system designed to provide high resolution performance for very large format cameras and sensor arrays in excess of 200mm diameter such as are used in aerial surveying.

Very large formats are required when multiple sensors are used in an array to overcome the limitation of simple and/or individual conventional sensors. However until now few optimised lenses have been available to realise the full potential of such systems.

Resolve Optics new very large format lenses provide an optimised solution to enable these products to achieve their full performance potential opening the door to exciting new applications. In order to achieve the high resolution right across the field-of-view requires that the lens elements must to be centred to a high degree of accuracy.  This accuracy is achieved via a novel mechanical design created by Resolve Optics.
