You could pick the filter’s dimensions and condition for on-demand customization and spot the buy on line at your comfort. When your filter is in stock, we could transform it in as little as at some point.
We offer a comprehensive choice of catalog filters, which includes our 266nm Raman laser longpass set and various specialized UV filters. For special necessities, our custom filter design and style capabilities guarantee you receive the best Alternative for your precise application.

Quite a few typical UV gentle sources are comprised of a number of vivid “traces” or wavelengths, with rather reduced emission stages among them. Widespread UV lamps contain gas discharge lamps (like minimal- and medium-strain Mercury lamps) and excilamps which emit gentle due to excimer or exciplex development from the energized condition in the gases within the lamp housing (Xenon, Krypton Chloride, etcetera).
Blocking in these lamps can be personalized to offer deep blocking at only the wavelengths of fascination, even though delivering large throughput at the specified wavelength. Contrary to extensive-band blocking, attained Using the steel coatings, absorption glass, or really thick interference stacks explained over, our engineers can improve the design for your desired wavelength, reducing cost and maximizing general performance.
Normal sample overall performance curves Smart Energy Meter demonstrated. Specific layout curves such as blocking effectiveness accessible upon request.
Our filters will also be optimized for detectors like photomultiplier tubes (PMTs) and silicon-centered sensors. This compatibility assures remarkable functionality throughout several UV applications which is backed by our sector top guarantee.
Sometimes, it's much easier to style and design a reflective filter inside the UV, which in transmission seems like a notch (or rejection band) filter, but when used in a reflective assembly as proven down below, can attain substantial effective transmission in excess of a slender wavelength variety.
Sputtered or ion-assisted PVD oxide-based mostly types can transmit over eighty% all the way down to about 250 nm and fluoride-dependent models can transmit even decreased. Under about 200 nm, measurements turn out to be tough as atmospheric Electricity Metering Device molecules begin to absorb. Unique gear is necessary to help make measurements at pretty very low wavelengths.

Irrespective of whether adapting an existing design or making a new a single, we make sure you attain the most beneficial effectiveness without having purchasing pointless capabilities.
What’s much more, our UV-IR filters present superb noticeable mild transmission, leading to significant brightness. These filters are produced with proprietary sputtered deposition technological innovation that provides Extraordinary security at substantial running temperatures and various humidity stages.
Performing from the UV (fewer than about four hundred nm) is often a problem for filter companies, since many of the generally used products start off to absorb light-weight at these wavelengths. Most interference filters are intended with the idea that light-weight is simply transmitted or mirrored and not absorbed. A further problem for the shorter pass and bandpass filters is wide-wavelength blocking.
