Fiber Delivery of Lasers in Bioinstrumentation

In many laser-based types of bioinstrumentation, including flow cytometers, confocal microscopes, and array readers for proteomics, laser output is delivered to the system’s final optics regime via fiber coupling. Over the past few years, this fiber delivery has evolved from simple remote delivery to finally encompass plug-and-play use of multiple lasers with sub-micron beam positioning accuracy. This capability is supporting a new generation of instruments that combine state-of-the-art performance with ease of use.

High Performance Laser Systems

Edmund Optics® (EO) (Barrington, NJ) is now offering Coherent® High Performance OBIS™ Laser Systems. The High Performance OBIS Laser Systems feature the same compact design used for all wavelength options, meaning the compact, plug-and-play lasers provide wavelengths from UV to NIR on a single platform. Each laser uses either the proprietary Optically Pumped Semiconductor Laser (OPSL) or the laser diode-based technology. Every system features the same beam parameters in packages that allow the user the flexibility to plug-and-play alternate wavelengths as needed.

Compact Laser Modules

The ZM12 range of small industrial laser modules from Z-LASER (Freiburg, Germany) is designed for industrial manufacturing processes such as laser marking or machine vision applications where superior quality and performance are elementary. With IP67 protection class it is resistant to water and dust. The basic model with optic head has a length of 85 mm and a diameter of 15 mm. With the external focus mechanism it is easy to manually change the beam shape. As a laser model with integrated cable (ZM12DM5) the laser is only 63 mm long. The laser configuration is available with red and infrared wavelengths, optical output up to 100 mW as well as modulation option up to 100 kHz. These properties allow an easy synchronization with a camera system or to setup the laser intensity via PWM (pulse-width modulation).

2013 Infrared Handbook

FLIR Systems (Croissy-Beaubourg, France) has announced an updated 2013 edition of its popular Infrared Handbook for R&D Professionals. Although infrared radiation (IR) is not detectable by the human eye, an IR camera can convert it to a visual image that depicts thermal variations across an object or scene. IR covers a portion of the electromagnetic spectrum from approximately 900 to 14,000 nanometers (0.9–14 μm). IR is emitted by all objects at temperatures above absolute zero, and the amount of radiation increases with temperature.

Solar Blind Filters

Optical Filter Source (OFS) (Austin, TX), teaming with Pellicori Optical Consulting (POC) (Santa Barbara, CA) has developed and demonstrated solar-blind UV filters for applications in the wavelength range covering the UV regions: UVA (300 - 400 nm), UVB (280 -300 nm), and the long-wave part of the UVC band (~225 – 280 nm). There is a need for UV bandpass filters in the UVC spectrum at wavelengths shorter than ~270 nm that possess extreme rejection of solar energy at wavelengths longer than ~300 nm. The solar spectrum contains >99% of its total energy at wavelengths longer than ~300 nm, therefore very high rejection is needed to permit the detection of UV energy.

Temperature Characteristics-Free Etalon Filter

Kyocera Corporation (Kyoto, Japan) announced that its wholly owned subsidiary, Kyocera Crystal Device Corporation, in charge of development and manufacturing of crystal devices, has succeeded in developing a temperature characteristics-free etalon filter — a crystal device which has applied the atomic diffusion bonding technique. An etalon filter is a component which detects deviations in multiple light wavelengths in high-capacity optical communication transmissions systems. Its external dimensions are >1.2mm squared; its adaptive wavelength is 1,520 to 1,620nm; temperature characteristics: ±0.15pm /°C typ. (pm/°C = 10-12m/°C); FSR: 50/100 GHz; and custom extinction ratio or reflectance.
