totaling about 15% of Teledyne DALSA’s revenue

• "ITAR free" solutions subject to Canadian export controls

• Broad capabilities• CCD and CMOS, radiation tolerance• Linescan, TDI, and areascan• High resolution (up to wafer scale)• High speed (up to 100 million fps)• Backside thinning• Hyperspectral and Multispectral

Multispectral and Hyperspectral Sensors

Multispectral Hyperspectral

Multispectral / Hyperspectral Comparison

A prism or grating is placed in front of sensor for separating different wavelengths

Patterned filter coatings form part of the sensor

Creates a hyperspectral data cube with narrower bands over a continuous range

Creates a dataset with narrow bands over discrete

frequency ranges

Has discrete spectral bands (typically < 20)

Has continuous spectral bands (typically 100s)

Used to discriminate features and patterns Used to identify and characterize materials

Higher resolution and relatively smaller dataset

Lower resolution and much larger dataset

Multispectral Sensors

Image Sensor - Silicon• Monolithic

• Compact design

• Different pixel sizes for P and B zones

• TDI design for increased sensitivity and throughput

• Special design & timing for low crosstalk

• Designed to withstand harsh environmental conditions

• A prism or grating placed in front of the sensor for separating different wavelengths

• Separated wavelengths fall on different rows of the image sensor

• Image sensor reads out the information for different wavelengths forming a hyperspectral data cube

Hyperspectral Sensors

Hyperspectral Sensors• Backside thinned for good QE• High frame rate (>300fps)• Fast transfer time (
