67-849 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 810nm
The 67-849 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically centered at 810 nm, with a full width at half maximum (FWHM) of 10 nm. The item data indicates that it is in stock, and users can access further details and order information through the provided weblink.
This filter is made of UVFS Mal-1965 material and has a thickness of 5.9 mm. The cut-on wavelength is 805 nm, and the cut-off wavelength is 815 nm, making it ideal for applications that require narrowband transmission in the near-infrared (NIR) region.
The 67-849 features front and back coatings of EDM 67-782, which are likely to enhance the filter's performance by reducing reflection and increasing transmission. The filter's shape is that of a thin lens, suggesting that it can be easily integrated into various optical systems.
