Our UV-IR filters protect polymer optics, microdisplay panels and optical components from dangerous UV light-weight. Additionally they decrease the warmth load on these components by blocking IR radiation.
We offer a comprehensive choice of catalog filters, like our 266nm Raman laser longpass established together with other specialised UV filters. For special requirements, our custom made filter design capabilities make certain you receive the best solution to your specific application.
The issue in making high-top quality UV bandpass filters is usually in seeking to block the entire obvious vary. The broader the blocking range, the thicker The skinny-movie stack plus the dearer the filter will be. At times, absorption glass can be utilized for noticeable mild blocking for bandpasses previously mentioned about 250 nm without the need of significantly influencing the transmission performance.
The drawbacks incorporate very low transmission (normally under twenty%) and spectral edges that aren't pretty steep.
The complex storage or accessibility that's used solely for statistical functions. The technological storage or accessibility that is applied exclusively for anonymous statistical purposes.
With decades of knowledge producing optical filters for demanding purposes, we realize the one of a kind difficulties you experience.
Dependable by pros throughout A variety of industries, our filters are designed to enhance overall performance and assure constant effects exactly where ultraviolet gentle is critical.
The least specified wavelength dictates regardless of whether oxide or fluoride supplies are employed for these filters. As within the UV band go filters, blocking of all visible wavelengths improves the complexity and cost with the filters.
Sputtered or ion-assisted PVD oxide-based mostly styles can transmit around 80% all the way down to about 250 nm and fluoride-based mostly styles can transmit even decreased. Under about two hundred nm, measurements grow to be difficult as atmospheric molecules start out to absorb. Specific gear is needed to create measurements at incredibly minimal wavelengths.

Coloration correction filters: Utilize a coloration correction filter with your UV-IR filter to match the correlated color temperature of 1 lamp to a different.
What’s more, our UV-IR filters give superb noticeable gentle transmission, causing large brightness. These filters are created with proprietary sputtered deposition know-how Smart Energy Meter that gives exceptional balance at substantial running temperatures and various humidity concentrations.
In addition, our thorough excellent assurance methods make certain that each individual filter we create continually satisfies your correct prerequisites, offering you with The boldness and comfort wanted for your personal crucial inspection applications.
