Do you also offer solutions for UV and SWIR applications?
Yes, we offer filters for SWIR wavelengths across our Bandpass, Longpass, Polarizers, ND, and Protective filter series. Applications using SWIR wavelengths have been trending for quite some time, and we’re consistently staying attuned to industry developments, continuing to innovate in this wavelength range. We also provide filters well-suited for imaging in the UV spectrum, such as our BP250, BP324, BP340, and BP365. Our BN and Bi series, which feature a narrower passband, are particularly effective if your goal is to use a UV light source to cause the material being inspected to fluoresce, helping to capture the weak emission wavelength. Using a filter for these types of applications ensures you’ll achieve the necessary contrast.
What about spectral imaging solutions for drone operations in agriculture?
We offer a line of multi-bandpass filters that are highly effective for agricultural inspections using drones, particularly when calculating NDVI values with a camera equipped with a CMOS sensor. Unlike typical bandpass filters, which have a single passband, multi-bandpass filters feature two or more passbands, enabling you to capture the necessary wavelength channels to calculate NDVI values using the appropriate software. This method allows you to assess the vegetative health of large agricultural areas without the need for full-sized aircraft or costly hyperspectral cameras. It’s a solution that’s become very popular among professionals and hobbyists.
Do you have solutions for blue lasers, which are increasingly being used in the metrology sector?
Yes, we offer several bandpass filters with passbands centered on blue wavelengths, including our relatively new BN450. This filter features a narrower passband to help mitigate issues caused by overwhelming ambient light, and it also incorporates our exclusive Stabledge technology. Thanks to its complex coating design, Stabledge allows the filter to be less susceptible to angle of incidence issues, which are common with filters available in the marketplace. This combination makes the BN450 an ideal choice for metrology and other 3D triangulation applications that require the utmost precision when measuring the position, distance, level, displacement, proximity, and profiles of objects.
