Our UV-IR filters defend polymer optics, microdisplay panels and optical elements from damaging UV light-weight. Additionally they lessen the heat load on these parts by blocking IR radiation.
We offer an extensive range of catalog filters, which include our 266nm Raman laser longpass established along with other specialised UV filters. For unique needs, our tailor made filter style capabilities assure you get the exceptional Answer to your specific software.
From the sputtered oxide filter under, the short wavelength edge (at about 280 nm is because of absorption in the coating materials).
The drawbacks incorporate small transmission (often underneath 20%) and spectral edges that aren't quite steep.
The traditional style of bandpass filters within the UV entails induced transparency in a very metal (typically Al or Ag). These filters are certainly affordable to make, comprising only A few layers and delivering substantial blocking around your complete seen wavelength selection.
Irrespective of whether You'll need a small modification to an present style and design or a completely novel filter, Chroma's expertise makes certain you receive the ideal functionality and value doable, tailored exactly to your application.
For additional filter customizations or massive quantity orders, get in contact with our product sales workforce. We’ll be pleased to discuss your preferences and share our amount special discounts to receive you the very best pricing.
Occasionally, it's easier to style and design a reflective filter in the UV, which in transmission looks like a notch (or rejection band) filter, but when used in a reflective assembly as proven under, can attain substantial helpful transmission over a narrow wavelength variety.
Sputtered or ion-assisted PVD oxide-based mostly styles can transmit around 80% all the way down to about 250 nm and fluoride-primarily based designs can transmit even decreased. Beneath about two hundred nm, measurements turn out to be tricky as atmospheric molecules Uv Optical Filters commence to soak up. Unique devices is required to generate measurements at very minimal wavelengths.
At Chroma Know-how, we supply Highly developed optical filter solutions that established the conventional for precision and trustworthiness in UV purposes.

Whether or not you need catalog filters or simply a personalized Remedy, Chroma is dedicated to delivering Sophisticated optical filters that produce outstanding overall performance and dependability. Get in touch with us now to discuss your necessities or ask for a quote.
Doing work during the UV (less Smart Energy Meter than about four hundred nm) is a challenge for filter producers, since most of the typically employed components commence to absorb light-weight at these wavelengths. Most interference filters are built with the idea that mild is only transmitted or mirrored and never absorbed. Yet another challenge with the limited pass and bandpass filters is wide-wavelength blocking.
For filter models beyond our catalog offerings, we pride ourselves on our ability to meet even probably the most tough filter needs. Our design and style method ensures that you get the exceptional filter in your application every time with our move-by-action approach:
