Cost-effective volume production of imaging mirrors
Aspheric mirrors offer considerable advantages over lenses in imaging systems, offering broader spectral coverage and no dispersion. They also eliminate aberration and ensure high resolution in a more compact design, making them key elements in spectrometers and analytical and astronomical optical instrumentation. Spectrum Scientific’s optical replication process offers high-fidelity, high-specification precision aspheric mirrors at a lower cost compared to traditional volume manufacturing. It also allows the incorporation of mounting or alignment features onto the mirror itself, improving stability and reducing assembly and alignment costs. Optical replication can accommodate different material choices and optical surface designs including OAPs and freeform mirrors and can produce typical surface figures of up to λ/10 or better. Using a process similar to nanoimprint lithography, it transfers the shape of a master optic to low- cost substrates with minimal part-to-part variation and is a highly cost-efficient method for high-volume production of aspheric mirrors.

camera manufacturer offering its own lens line. The company’s C-mount lens series provides resolutions of 5, 8 and 10 megapixels, as well as focal lengths of 4 to 75mm and different optical classes. The lenses cover sensor sizes from ½-inch to 1.1-inch. The aperture and focus can be fixed mechanically if required, which ensures brightness and image quality remain constant, even if the lens is exposed to vibration. Available from Edmund
Optics is a range of imaging lenses for a variety of imaging needs, including telecentric
lenses, liquid lenses, those with fixed focal length, zoom lenses, and shortwave infrared imaging lenses. A selection of imaging lens accessories is also available, including filters, and mounts or adapters for additional functionality. Fujifilm offers a wide range of prime, zoom and telephoto lenses. Its most recent launch is the Fujinon GF35-70mm interchangeable lens for large- format cameras. Designed as a compact and lightweight zoom lens, it weighs around 390g, with a focal length range covering from 35mm to 70mm. The company
