Products Description
BP1000nm Bandpass Filter | 10nm FWHM, OD3+ Broad Blocking
The OPTOStokes BP1000 is a precision NIR bandpass filter engineered for accurate spectral selection at 1000nm. With over 90% peak transmission at the central wavelength, a narrow 10nm full-width at half-maximum (FWHM), and high optical density blocking across the 350–1100nm range, this filter delivers reliable performance for demanding near-infrared optical systems. It is fabricated using advanced thin-film coating technology on high-quality optical substrates, ensuring consistent spectral response, low environmental drift, and long-term durability for both industrial and laboratory applications.
