Zoom lenses
Continuous zoom lenses for long-range surveillance: the built Z25 visual zoom and a SWIR design based on the same concept.
- Z25: 9 to 320 mm, 25× optical zoom, f/3.8 to f/6.8, visible band. Built.
- SWIR zoom: 18 to 430 mm, 24× optical zoom, f/3 to f/5.6. Designed, based on the visual zoom concept.
Z25 visual zoom
Developed for long-range surveillance in security, military and industrial applications. It gives a 1° horizontal field of view at Full HD 1080p with 25× optical zoom, in a 46 × 58 × 149.5 mm body. With the focus group and sensor protruding, overall length is about 175 mm.
It is matched to a 5-megapixel sensor with 2,592 × 1,944 pixels of 2.2 µm, used by several camera makers. Crop the image electronically by 26% to 1,920 × 1,080 for Full HD; electronic zoom then takes the total zoom ratio past 34×. Without cropping, the four corners show slight vignetting at the widest setting.
A simple GUI sets zoom position and focus distance. Stepper motors with high-precision position calibration, a wide operating temperature range with built-in temperature compensation, vibration qualification to military specification, excellent boresight repeatability and very low boresight shift through zoom make it ready for airborne, ground and naval use.
