LENSES AND OPTICS
UV MicroSpot focusing objectives Thorlabs’ high-power UV MicroSpot focusing objectives are designed for use with UV excimer lasers and other ultraviolet sources in on-axis laser focusing and micro-imaging applications. The objectives contain lens elements made from high-quality, low absorption, excimer- grade fused silica or CaF2. These lenses are AR-coated and optically designed for narrowband or broadband wavelength. As the latest additions to Thorlabs’
Coating of fibre end faces
Laser Components has expanded its range of services for the coating of fibre end faces. The company is now in a position to produce larger quantities and, at the same time, has created ideal conditions for processing other fibre types. This means that customers benefit from
a larger product range and price advantages through cost-efficient production. Depending on assembly configuration, the company can now process fibres with large
IQ Lab optical metrology services
Optikos’ IQ Lab service offers clients a range of lens and camera testing in one location. Measurements offered include both veiling glare index (VGI) and glare spread function (GSF) to assess stray light, as well as an expanded menu for testing lenses over temperature. VGI is a quick measurement that is
useful for evaluating the overall stray light ‘health’ of a lens, and because the measured VGI performance of a lens is summarised in a single number, it can easily be used to compare performance across multiple suppliers. GSF is a more comprehensive measurement that can provide insight into the origin of stray light issues, and is often the measurement of choice for challenging
bending radii or very large core diameters up to 1,000µm. This opens up additional possibilities, especially in the field of multimode fibres. An improved ion source has also enhanced
the surface quality of anti-reflective coatings. Depending on the coating and wavelength, Laser Components achieves back reflections from 0.5 to 0.2 per cent. Back reflections can impair their function or even damage components, especially when coupled into active elements.

imaging environments such as automotive lenses or lidar systems in which solar glare is a significant issue. IQ Lab measurements for benchmarking
lenses over temperature now cover an extended temperature range (-20°C to 100°C) and use easily customised fixtures for testing relatively small imaging automotive camera lenses, larger lidar type lenses, imaging lenses mounted in large housings or with large windows attached, and everything in between. Over the past several years, Optikos’ IQ Lab and R&D engineers have refined techniques used to make these measurements, and recently introduced a Thermal Module product line as an option for Optikos lens testing systems.

MicroSpot series, the LMUL-10X-UVB, LMUL-20X-UVB, and LMUL-50X-UVB Focusing Objectives are optimised chromatically across UV and visible wavelengths, while featuring longer working distances and larger fields of view than their predecessors. With lenses crafted from high-quality, low-absorption fused silica and calcium fluoride, and an air-spaced optical design, they are suitable for laser focusing and micro-imaging applications with high-power excimer lasers, or other UV sources. To meet the tight manufacturing
tolerances required by the optical design, Thorlabs has invested in an ultra-high precision alignment turning machine. After being mounted in their housings, optical elements are turned with ultra precision, to achieve minimal deviation between the mechanical and optical axes and ensure the correct spacing between lens vertices. Finished lenses are assembled in an ISO 7-rated clean room.
