Imagine Optic’s HASO NIR offers professionals unsurpassed quality, precision and ease of use in the mostly used NIR bandwidth. Key features include:

• 1500 - 1600 nm wavelength range with high precision

• Optimizing fiber coupling and, more generally, for aligning and characterize optical systems in the NIR

• simultaneous and independent measurement of both phase & intensity

• true absolute measurement

• unbeatable accuracy and dynamic range


Our HASO NIR Shack-Hartmann wavefront sensor is the ideal tool for customers working in the near infrared spectrum (1500 - 1600 nm).  Exceptionally easy to integrate, they provide fast, accurate and reliable measurements by taking advantage of the HASO family’s standard functionalities that customers have come to rely on, including absolute measurement, unequalled accuracy and insensitivity to vibration at speeds up to 60 Hz.
HASO NIR is the ideal tool for fiber coupling and, more generally, for aligning and characterize optical systems in the NIR (afocal, collimators, lenses, zoom, etc.).  When coupled with our HASOv3 software, it enables you to perform both zonal and modal wavefront reconstruction; calculate the PSF*, MTF* and Strehl ratio*; visualize the spot diagram; and obtain the M²* parameter.
