Planar Diffraction Gratings suit laser system applications.

Available for 633–1064 nm waveband with 1,600 lines/mm, LA Series exhibits diffraction efficiency of 98%, which is critical to expansion and compression of laser pulses for light sources used in laser processing. Gratings can also be used in analytical instruments for research in life sciences, chemistry, and environmental monitoring, as well as synchrotron radiation and optical communications....

Diffraction Gratings feature aberration correction.

Guaranteed to meet groove profile and density specifications from prototype to production, Holographic Diffraction Gratings are aberration-corrected, meaning that unwanted optical effects such as keystone and smile are eliminated. Small-form-factor, temperature-insensitive products offer high SNR and low stray light performance. Applications include color management, plant phenotyping, pathogen...

UV Transmission Gratings disperse light for fixed applications.

Manufactured from UV grade fused silica substrate, UV Transmission Gratings are suited for applications in 250-450 nm wavelength range. Units are relatively polarization insensitive and are fairly impervious to alignment errors. When incident light strikes gratings' coarse groove spacing, it is dispersed to opposite side of grating at fixed angle. As groove spacing increases, diffraction angle...

How to Effectively and Efficiently Clean Heat Exchangers, Part I

For refineries and petrochemical plants, cleaning heat exchangers is a dirty job but somebody has to do it. While there are many approaches on how to clean shell and tube heat exchangers, it is indisputable that the right method is absolutely critical for ensuring that equipment is fully operational. Otherwise, you could end up with a potential equipment shutdown, which will cost you time and money. In this three-part series, you will learn about the various benefits, methods, and obstacles involved in heat exchanger cleaning. Part one introduces the fundamentals of cleaning, as well as explores the pros and cons of on-site versus off-site services. Download the first of this three series to assist you in finding the best solution for your dirty job here.
