Our UV-IR filters guard polymer optics, microdisplay panels and optical elements from destructive UV light. They also reduce the heat load on these elements by blocking IR radiation.
We offer an extensive number of catalog filters, which includes our 266nm Raman laser longpass established as well as other specialized UV filters. For exceptional requirements, our customized filter style and design abilities be certain you receive the optimum Remedy in your correct software.
The difficulty in producing higher-good quality UV bandpass filters is often in endeavoring to block the entire visible array. The wider the blocking assortment, the thicker the thin-film stack as well as the costlier the filter is going to be. From time to time, absorption glass may be used for noticeable mild blocking for bandpasses over about 250 nm with out significantly influencing the transmission performance.
We understand that the trustworthiness and regularity of our filters are vital for your devices accomplishment. That is why we maintain demanding top quality Manage steps through our manufacturing procedures. Being an ISO-Licensed company, we adhere to demanding expectations inside our operations.

The bare minimum specified wavelength dictates whether or not oxide or fluoride components are employed for these filters. As in the UV band move filters, blocking of all noticeable wavelengths improves the complexity and value of the filters.
We also provide your optics in the exact substrate, dimensions and condition you need to your application. Regardless of what your requirements might be, we’ll operate with you to search out the ideal filter solution.
Simulation and Prototyping: We use proprietary optical modeling tools to simulate filter effectiveness and, when required, build prototypes for testing.
Straightforward filter styles have only blocking approximately ~20% of the middle wavelength – far more substantial blocking may be attained by incorporating a metal layer which noticeably lowers the %T within the transmitting location, including a coloured glass absorbing filter, or by adding dielectric levels (As an example, introducing a short-move filter style to one other aspect of your substrate).
IR light-weight is invisible for the human eye, but it surely gets to be a concern when utilizing a digital camera. A digital camera’s silicon sensor may be very delicate to IR light, resulting in blurry photos. Electricity Metering Device By blocking UV and IR gentle with considered one of our UV-IR filters, you’ll have the high-high quality photos you require for your personal software.
Moreover, our complete quality assurance strategies be certain that each and every filter we produce continuously meets your correct demands, supplying you with The boldness and reassurance wanted to your significant inspection programs.
For filter layouts outside of our catalog offerings, we pleasure ourselves on our ability to meet up with even probably the most hard filter requirements. Our layout system ensures that you have the exceptional filter for the application whenever with our move-by-step method:
