TwinFilm technology was developed by Spectrolight to provide a simple and cost-effective means to filter light according to wavelength. This patented, next-generation technology provides a superior alternative to monochromators and AOTFs in fluorescence microscopy, hyperspectral imaging, machine vision and other applications.
Spatter-Free Stable Conduction and Keyhole Welding of Copper with 275 Watt Blue Laser
7 pages | 27 November, 2018 | PDF | 1.1 MB
Laser welding of highly reflective materials such as copper has been problematic for infrared lasers due to the low initial energy absorption of the material during the welding process. This paper will report on the recent bead-on-plate test results using a 275 Watt CW 450 nm blue laser for welding copper foils up to 500 μm thick where the initial absorption is ~65%.

Designing with UVC LEDs to Combat Hospital Acquired Infections (HAIs)
3 pages | 27 October, 2017 | PDF | 335 KB
Hospital acquired infection (HAI) is a major problem resounded throughout the land. It is spread to the susceptible patient in the clinical setting by various means. In order to minimize this risk small, portable hand-held devices with UVC LEDs can be used for disinfection. In this Laser 2000 Wiki whitepaper you can read about UVC disinfection solutions of pathogens in hospitals.

One of the most critical element of any laser system is the alignment of the laser beam throughout the whole beam path until the desired target.
Frameless Mirror Holders and the Use of Ceramic Substrate
4 pages | 31 May, 2016 | PDF | 730 KB
The mirror is clamped in conventional optical mirror assemblies. Mechanical and thermal instabilities are created by clamping, which lead to disturbances in the measurements on precise optical constructions. A ‘frameless system’ offers the advantage that the entire mirror aperture can be used, especially in small spaces.see Wiki

Machine Vision – Laser Image Processing
4 pages | 01 November, 2016 | PDF | 120 KB
Why should lasers be used for image processing? Because they enable fast image captures, derive reliable distinguishing features, and work reliably in all environmental conditions. But what are the characteristics and requirements for a laser used in this way?
High-performance SWIR Imaging Cameras
11 pages | 31 May, 2015 | PDF | 1.62 MB
Silicon-based area detectors (such as CCDs or CMOS) are widely used in high-performance imaging applications, detecting wavelengths from soft x-ray through to near infrared (NIR). Typically, the quantum efficiency (QE) of these detectors decreases rapidly as the detection wavelength increases further into the NIR region.

Messen mit dem OTDR – ein Klassiker und doch immer wieder neu
13 pages | 20 November, 2017 | PDF | 1.70 MB
OTDRs sind für Abnahmemessungen von Glasfaserkabeln und die Fehlersuche ein unersetzliches Werkzeug. Sie bieten als Einzige die Möglichkeit, Einzelereignisse auf einer Glasfaserstrecke zu qualifizieren und zu quantifizieren. In der Vergangenheit kamen sie meist nur in Weitverkehrsnetzen zum Einsatz. Heute werden Glasfasern im Zugangsbereich bis ins Haus verlegt und damit sind deutlich andere technische Parameter beim OTDR gefordert notwendig.
