CIE publishes Technical Report CIE 259:2026 on visual ergonomics for display equipment
The CIE has published Technical Report CIE 259:2026, "Visual Ergonomics, Lighting and Visual Display Equipment" (ISBN 978-3-902842-81-7, DOI 10.25039/TR.259.2026). The report updates guidance on display screens, reflecting advances in display and computing technologies and addressing newer personal devices, varied viewing positions, advanced control functions, and potential adverse effects of prolonged screen use. It consolidates peer-reviewed visual ergonomics principles for indoor work environments, covering user health, digital eyestrain, spectacle lenses, display characteristics, lighting and environmental modifications, and metrics-related issues. The 35-page report includes two tables and is available from the CIE Webshop and National Committees.

DALI Part 151 certification reaches products, targets surge protection for outdoor lighting
DALI Part 151 has moved from specification into certified products, giving manufacturers a defined framework for surge protection of DALI control devices exposed to induced electrical transients in outdoor lighting. The specification addresses protection needs where control lines extend beyond luminaires to remotely mounted sensors or controls. TE Connectivity’s LUMAWISE Endurance bridge assembly is among the first products certified to Part 151, providing 800 V surge protection on DALI and auxiliary lines and offering pole- and wall-mounted options for retrofit and new installations. The certification illustrates practical application of the specification in connected outdoor lighting.

Tresky eliminates the need for an optical beamsplitter during DIE bonding
Tresky GmbH has developed a digital beamsplitter that replaces traditional optical components in die bonding systems by digitally merging camera images. The software eliminates light loss, reflections, and mechanical alignment challenges while maintaining full resolution and enabling flexible image adjustments. Designed for precision applications, it supports R&D, prototyping, photonics, optoelectronics, and advanced packaging.
