Diffractive optical element for efficient laser brazing

Diffractive optical element for efficient laser brazing
Holo/OR, industrial partner of LASER COMPONENTS, has developed a diffractive optical element (DOE) that accelerates the laser brazing process for hot-dip galvanised metal sheets. It provides better melting performance and cleaner edges at the same time. The DOE made of UV fused silica has an efficiency of 90%. It forms three beams with different diameters and power levels. Two smaller stripping beams ensure that the zinc coating is preheated, cleaned and preconditioned for brazing.

Infrared detectors suitable for fit and forget applications

Infrared detectors suitable for fit and forget applications
LASER COMPONENTS has introduced industrial grade thermal detectors, from their research and production facility in Arizona. These detectors work on the principle that photons incident on the polycrystalline thin film, promote electrons across the bandgap increasing the conductivity of the material, in turn decreasing the resistance of the substance.

Automated testing of multi-fibre connectors

Automated testing of multi-fibre connectors
LASER COMPONENTS has recommended the MPO switch from VIAVI Solutions for quick and easy OTDR testing of MPO multi-fibre connectors. In combination with an optical reflectometer and a base unit such as the MTS-4000 V2, it ensures that all twelve fibres of the MPO connector are tested for their attenuation, as it automatically switches from one to the other. Thus, the fibres no longer have to be tested individually using fanout cables.

TLC optics eliminates the wait for thermal stability

TLC optics eliminates the wait for thermal stability
For high power laser applications, thermal lensing can be an issue. Focal length can vary with running time as a result of heat build-up in optics due to power throughput. The TLC, or Thermal Lensing Compensation optic design from Haas Laser Technologies, passively compensates for thermal lensing for high power collimators and focal lenses. Thermal lensing for lasers with powers in excess of 1kW is reduced to less than the Rayleigh range of the lens design, through careful selection of materials and optical design.

IBS mirror coatings in the wavelength range 248nm to 3000nm

IBS mirror coatings in the wavelength range 248nm to 3000nm
LASER COMPONENTS now has Ion Assisted Deposition (IAD) and Ion Beam Sputtering (IBS) coating capabilities. Being a precise and replicable method, IBS coatings are used for the most spectrally demanding applications, such as steep edge dichroic mirrors and very broad band mirrors. Unlike other coating technologies, process parameters such as beam energy, layer growth rate and oxidation level, can be individually regulated to a high precision during the coating process.

The use of pyroelectric detectors for non-contact temperature

The use of pyroelectric detectors for non-contact temperature
Every object emits heat in the form electromagnetic waves and sampling the energy radiated into space allows the measurement of the temperature of the object without ever having to touch it. The wavelength of the light emitted by the object depends on its temperature, with hotter objects generating light at shorter wavelengths. Thermal detectors have the widest wavelength response with the limiting factor being the transmission window used to protect the sensing element.

New Director of Production at LASER COMPONENTS

New Director of Production at LASER COMPONENTS
Christian Grunert has been appointed Director of Production for Laser Optics at LASER COMPONENTS. The 37-year-old engineer succeeds Uwe Schallenberg, who has been working in thin-film coatings since 1977 and served as head of this key department since 2014. Grunert is not new to the world of dielectric coatings, beam splitters, and mirrors. At university, he focused on lasers and optotechnology. After that, these technologies remained at the centre of his professional career.

Laser optics help keep fruit and vegetables fresh

Laser optics help keep fruit and vegetables fresh
Diffractive Optical Elements (DOEs) allow laser beams to be split, bundled, or formed into almost any shape and are used in multiple applications. The food industry, for instance, uses them for laser perforation, when it comes to applying micro holes into packaging for fruit or vegetables. These allow the food to 'breathe' and thus extend its storage life. The holes have diameters of between 50-300μm depending on the type of food and material.

Interference filters can absorb visible-NIR

Interference filters can absorb visible-NIR
Interference filters are widely used in a transmissive configuration, whereby light passes through the filter to cause some effect, be that band-pass, short-pass or long-pass etc. By nature, interference filters do not generally absorb in the visible-NIR, but instead light is either transmitted or reflected. That makes transmissive interference filters suitable for applications within this spectral range.

Pyroelectric detector uses a differential mode of operation

Pyroelectric detector uses a differential mode of operation
Pyroelectric detectors are susceptible to line interference and other sources of electromagnetic interference from non-detector related noise. Several manufacturers of OEM sensor devices use EMI filters to prevent these noise sources interfering with the operation of the device but for many gas detection applications a higher level of noise immunity is required.

Pyroelectric detectors recombines beams and directs sample

Pyroelectric detectors recombines beams and directs sample
Fourier transform infrared spectrophotometry has become a well-established alternative to dispersive spectrophotometry, using prisms or gratings. An FTIR interferometer splits one beam of light from a broadband source into two using a beam splitter, transmitting the first beam to a fixed mirror and the second to a mirror that is translated back and forth very precisely so that the paths of the two beams are different.
