Zoom Lenses
Beck Optronic Solutions offers several high performance ruggedised zoom lenses suitable for long range surveillance, border control and remote weapons stations. These include a 150-1200 mm lens designed to operate over the entire spectral band of a naked silicon detector, a 13-286 mm lens for the visible and near infrared wavebands, a 22-220 mm lens for the visible waveband and 20-200 mm, 26.5-265 mm, 33-330 mm, and 53-530 mm lenses designed to operate in the SWIR waveband.
13-286 mm Zoom Lens for Visible and NIR
Beck Optronic Solutions offers a high performance ruggedised zoom lens suitable for long range surveillance and border security in the visible and near infrared wavebands.
In addition to the normal zoom facility key features include:
- Apochromatic correction to work over the entire spectrum from 400-1100 nm for high performance in low light levels.
- Fully automated for remote control.
- Built to comply with MIL Standards.
- Customisable to meet specific requirements.

SWIR Zoom Lenses
Beck Optronic Solutions offers high performance ruggedised zoom lenses suitable for long range surveillance and border security in the SWIR (0.7-1.7 µm) waveband for use with the latest indium gallium arsenide (InGaAs) detectors.
In addition to the normal zoom facility key features include:
- Apochromatic correction to work over the entire spectrum from 0.7-1.7 µm for high perfomance in low light levels.
- Optical design optimised for SWIR rather than just coated for SWIR.
- Fully automated for remote control.
- Built to comply with MIL Standards.
- Customisable to meet specific requirements.
