Hyperspectral imaging filters to be showcased at SPIE Photonics West 2017

Delta Optical Thin Film will showcase its continuously variable bandpass filters forhyperspectral imagingat SPIE Photonics West 2017. The filters are developed for mid-size and full-frame CCD or CMOS sensors (e.g. 25 mm x 25 mm or 24 mm x 36 mm) and offer very high transmission levels and are fully blocked in the light sensitive wavelength range of silicon-based detectors (200 nm to 1150 nm or higher). Currently, three models of the filters, which feature a blocking level of OD4, are available:

• Center wavelength range of 450 to 880 nm, bandwidth approximately 2% of center wavelength, transmission 60 to 90%, blocking range 200 nm to 1150 nm, for sensor size 24 x 36 mm.
• Center wavelength range of 450 to 850 nm, bandwidth approximately 4% of center wavelength, transmission 70 to 90%, blocking range 200 nm to 1100 nm, for sensor size 25 x 25 mm.
• Center wavelength range of 796 to 1084 nm, bandwidth approximately 1% of center wavelength, transmission >85%, blocking range 200 nm to 1150 nm, for sensor size 32 x 18 mm.

Combined with silicon detectors, these filters enable the design of compact and affordable hyperspectral imaging detectors, according to Delta Optical Thin Film.
