TECH FOCUS: OPTICS FOR IMAGING Resolve Optics FEATURED PRODUCT
lens. They offer high-speed adjustment of focal length to compensate for working distance deviation. Thorlabs offers a wide
variety of C-mount camera lenses, including standard fixed lenses, zoom lenses, high- magnification zoom lenses for macro applications, modular zoom lens components, and telecentric lenses. These lenses are compatible with all of the company’s CCD and CMOS cameras. Thermal imaging lenses are available to focus infrared light without introducing spherical aberration, and the company offers objective, scan, and tube lenses for use in optical systems for machine vision applications.
Tamron recently expanded its
range of fixed focal length lenses for the machine vision market with the MA23 and MA111- VIR series. The MA23 series targets industrial inspection with its small size and image quality optimised for shorter distances. The MA111-VIR series is optimised for larger sensor sizes and resolutions, with 1.1-inch sensor format and up to 24-megapixel resolution, addressing a large field of industrial and non-industrial high-resolution applications. This is not an exhaustive list.

Spectrum Scientific FEATURED PRODUCT
Custom radiation resistant lenses: As market leader in radiation resistant lenses for nuclear, space and medical applications for more than two decades – Resolve Optics has an unmatched range of standard fixed focus and zoom lens designs to draw upon. Adapting one of these existing designs enables Resolve Optics to
quickly produce a radiation-resistant lens optimised to suit almost any application. All optical elements within the company’s radiation resistant lens designs are made using cerium oxide doped glass or synthetic silica, enabling them to withstand radiation doses of up to 100,000,000 rads without degradation of performance.

Thanks to the absence of translational mechanics, these lenses focus within a few milliseconds, ensuring robustness and reliability with a lifetime of billions of cycles, for use in applications such as quality control, packet sorting, box filling, palletising, barcode reading, robot vision and 3D image stacking. Resolve Optics offers compact fixed and zoom lenses for vision applications including parts recognition, precise component placement, automated alignment and placement, and automated inspection. The company recently reported how its custom designed high-contrast shortwave-infrared lenses have been used for agricultural sorting applications by optimising both the resolution

and imaging contrast achievable with the product. A recent addition from Schneider-Kreuznach to its range of Zirconia lenses is the Zirconia 3.3/90. Designed for line sensors, it has a common magnification 0.1x. The main fields of application are flat panel display and PCB inspection. It has a uniform imaging performance over the whole field of view and comes with a V48 mount. Sill Optics provides a range
of telecentric lenses for machine vision applications. It offers products including lenses with coaxial light coupling to entocentric macro and wide- angle lenses, and telecentric illumination. Recent additions include the S5VPJ0303 and S5VPJ0305 telephoto lenses, including a tunable liquid
Cost-effective volume production of imaging mirrors: Aspheric mirrors offer considerable advantages over lenses in imaging systems, providing broader spectral coverage and no dispersion. They also eliminate aberra- tion 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.
