Quality Assurance: Every filter undergoes rigorous testing to meet our exacting benchmarks along with your specific necessities.
To optimize filter performance, look at matching your UV-IR filter with An additional style of optical filter. Some complementary filter types incorporate:
The difficulty in developing large-high-quality UV bandpass filters is often in wanting to block the total seen array. The broader the blocking array, the thicker the thin-film stack as well as the more expensive the filter will likely be. Often, absorption glass can be utilized for visible light-weight blocking for bandpasses higher than about 250 nm without the need of considerably influencing the transmission functionality.
The drawbacks incorporate very low transmission (normally less than twenty%) and spectral edges that are not extremely steep.
Blocking in these lamps may be personalized to supply deep blocking at only the wavelengths of desire, although providing significant throughput at the specified wavelength. As opposed to wide-band blocking, reached Using the metal coatings, absorption glass, or quite thick interference stacks explained higher than, our engineers can improve the look for your desired wavelength, minimizing Expense and maximizing performance.
Standard sample effectiveness curves demonstrated. Precise structure curves including blocking overall performance obtainable on request.

UV absorption can be a bonus in creating UV Extensive Pass filters for the reason that many of the OD blocking could be supplied by absorption instead of reflection. Sharp Slice-on edges can be optimized working with conventional interference style and design techniques.
Toughness: Designed to face up to severe environments, such as submersion or substantial-temperature disorders. Chroma filters can also be intended to Use a superior damage threshold for dealing with powerful laser or arc lamp sources.

Regardless of whether you would like catalog filters or perhaps a customized Remedy, Chroma is committed to supplying Superior optical filters that deliver superior overall performance and trustworthiness. Call us currently to discuss your prerequisites or request a estimate.
Operating while in the UV (fewer than about four hundred nm) is often a problem for filter suppliers, because a lot of the usually made use Smart Energy Meter of products start off to absorb light-weight at these wavelengths. Most interference filters are made with the assumption that gentle is only transmitted or mirrored and not absorbed. A further challenge for that quick go and bandpass filters is vast-wavelength blocking.
