Wide-passband filter transmitting a broad SWIR window (1000 – 1130 nm) with steep edges and deep blocking on both sides for clean spectral isolation.
MBP-A49 Bandpass Extended delivers Passband 1000 – 1130 nm, Bandwidth (FWHM) ~164 nm, and Centre wavelength ~1065 nm (nominal).
The hard-oxide coating is built for repeated handling, heat, and cleaning.
Best suited for:
Near-infrared imaging and sensing applications — including silicon-sensor camera systems, LIDAR receivers, and night-vision optics — where the wide NIR passband maximises signal collection across the sensor's peak sensitivity range
MBP-A49 is a dual-band bandpass filter operating entirely in the short-wave infrared (SWIR) range, transmitting two high-throughput windows at 1010–1135 nm and 1370–1570 nm while blocking the visible, NIR, and inter-band regions to deep extinction. The first SWIR passband delivers Tavg above 98.4 % with a peak of 99.3 %, and the second reaches Tavg above 99.0 % with a peak of 99.6 %. Blocking is exceptionally deep: Tavg < 2 % from 800–965 nm, 1185–1305 nm, and 1645–1800 nm, and visible-range transmission sits well below 1 %. The combination of near-unity passband transmission and deep inter-band rejection makes MBP-A49 a precision instrument for dual-channel SWIR analysis.
