Lens Selection Overview
This section provides an overview to selecting a lens for the Linea SWIR GigE camera. Mechanical
drawings and Teledyne DALSA part numbers for available lens adapters is provided.
Lens Mount and Lens Image Circle are important for correctly matching the lens to the sensor.
Brief information on other lens parameters to consider follows those sections.
For best performance, use a lens designed for short wave infrared wavelengths between 900 and
1700 nm. Note: Standard lenses designed for visible light may not transmit IR light fully or
perform to specification outside of their intended wavelength range.
There are several manufacturers producing C-mount SWIR lenses specifically designed for machine
vision systems. For assistance selecting suitable optics, please contact our regional sales offices.
