Delta Optical Thin Film will showcase its Bifrost line of continuously variable bandpass filters for hyperspectral imaging at SPIE DCS 2019. The Bifrost filters are designed for use with mid-size and full-frame CCD/CMOS sensors, and there are currently three models of Bifrost filter available.
The first model has a center wavelength range of 450 nm to 850 nm with bandwidth of approximately 4% of center wavelength. Transmission is 70% to 90% with a blocking range of 200 nm to 1100 nm, and is designed for a maximum sensor size of 25 x 30 mm.
The second model has a center wavelength range of 450 nm to 950 nm with bandwidth of approximately 2% of center wavelength. Transmission is 20% to 90% with a blocking range of 200 nm to 1200 nm, and is designed for a maximum sensor size of 36 x 30 mm.
The third model has a center wavelength range of 800 nm to 1100 nm with bandwidth of approximately 1% of center wavelength. Transmission is greater than 85% with a blocking range of 200 nm to 1150 nm, and is designed for a maximum sensor size of 18 x 23 mm.
Delta Optical Thin Film will show at SPIE DCS in Booth #756.
