As nations turn to LED lighting to save energy and cut emissions, industry players are still chasing efficiencies and searching for the elusive, right light, reports Rebecca Pool
This white paper presents and discusses the most common types of illumination for machine vision in order to help make illumination selection less intimidating.
How optical designers can realise the benefits of using freeform optical elements from the R&D stage when designing for illumination applications
How solid-state light engines can meet the exact needs of many biotech and industrial applications
The science of measuring the amount, spectral and spatial distribution of light emitted by a source is generally poorly understood. Few university-level physics or engineering syllabuses review the principles of optical radiation measurement, let alone the practicalities. This is despite our interacting with light almost constantly, both in nature and in our work and leisure activities. This white paper reviews the fundamental principles of light metrology.
Freeform optical elements give optical designers new and exciting degrees of freedom when it comes to designing optics for illumination applications. These same freeform elements can also add a new layer of complexity to the design process due to added degrees of freedom.
Specifications for illumination systems for biomedical imaging and industrial metrology generally converge on spectral, spatial and temporal light output characteristics. This article describes some of the ways in which solid-state light engines consisting of arrays of solid-state light sources, a mix of LEDs, light pipes and lasers, allow for the customisation of specifications to meet application-specific lighting requirements.
When Solid State Supplies added PAX pulsed xenon light sources to its Excelitas illumination solutions, it was the latest step in a fruitful photonics partnership

Launched at Photonics West, the VCSEL with stable linear polarisation and meta-optics uses only two components to create both flood and structured light illumination
This white paper provides operating lifetime projections for Lumencor’s light engines based on an analysis of service histories, cost considerations of solid-state light engines v. arc lamps, and a presentation of optical output stability data.

As microscopes become ever more powerful, a growing band of businesses are racing to make the latest technologies more accessible and more affordable, reports Rebecca Pool
Illustration of a three-dimensional crystal with various types of confining centres. (a) Crystal with four confining centres, each trapping waves (yellow) in all three dimensions simultaneously. (b) Crystal with a linear confining centre where waves can propagate in one dimension, analogous to an optical fibre. (c) Crystal with a planar confining centre where waves can propagate in two dimensions, analogous to a 2D electron gas. (Image: Vos et al.)
