REFRACTING
LENSES

Small, rugged, low distortion and a-thermal design are some of the qualities of this little refracting lens. It has excellent performance from axial to edge of the field across the visual and NRI spectral ranges. Fitted with a 2/3″ CCD the horizontal field of view is 37 degrees.

The R0306005VN has been in production for many years and have proven itself in the military arena.

This specific lens is fitted with 2x mounting rings which electrically isolates the camera assembly from the frame. 

The mechanical length is <45mm, and housing diameter of 26mm, with mountain diameter of 33mm and front to image plane distance of about 60mm. 

The horizontal field angle is 16.7 ° with a 2/3″ CCD. 

With a 5μm pixel sensor, at the Nyquist frequency of 100cy/mm, the lens achieves 50% modulation on-axis and >40% on the edge of the field.  

The R0505009V is a simple and tough lens with excellent performance in the visual spectrum.
This specific lens was designed to have a large, 18mm image diameter for larger format sensors.
The mechanical length is 68mm from front to image plane and housing diameter of 20mm, with mounting diameter of 18mm.
With a 5μm pixel sensor, at the Nyquist frequency of 100cy/mm, the lens achieves 60% modulation on-axis and >50% on the edge of the field.

The R0705005BW has been in production for many years and was designed to be paired with a B/W sensor. In order to improve atmospheric visibility, this lens was provided with an orange filter transmitting wavelengths from 55nm to 1000nm. Other 70mm EFL lenses are available for the visible spectrum.
This specific lens is fitted with 2x mounting rings which electrically isolates the camera assembly from the frame.
The mechanical length is 80mm from front to image plane and mounting diameter of 26mm, with flange diameter of 33mm.
The horizontal field angle is about 7.2° when fitted with a 2.3” CCD.
With a 5μm pixel sensor, at the Nyquist frequency of 10cy/mm, the lens achieves >50% modulation on -axis and >40% (Tan and Sag average) on the edge of the field.

The R1386005VN has been in production for many years and have proven itself in the military arena.
