At the Conference on Hyperspectral Imaging in Industry 2018 from June 6-7, Delta Optical Thin Film will showcase its newly-launched continuously variable bandpass filtersthat are specifically designed for hyperspectral imaging. The filters are designed for mid-size and full-frame CCD/CMOS sensors and are currently available in four models:
- Center wavelength range of 450 nm to 880 nm, bandwidth approximately 2% of center wavelength, transmission 60% to 90%, blocking range 200 nm to 1150 nm.
- Center wavelength range of 450 nm to 880 nm, bandwidth approximately 4% of center wavelength, transmission 70% to 90%, blocking range 200 nm to 1100 nm.
- Center wavelength range of 800 nm to 1100 nm, bandwidth approximately 1% of center wavelength, transmission >70%, blocking range 200 nm to 1100 nm.
These sizes are given as height x length, where height is perpendicular to the wavelength gradient and length is along the wavelength gradient. The filters can also be diced to smaller sizes.
