Kaleo MultiWAVE

Spectral Range UV (190 - 400 nm) VIS - NIR (400 - 1100 nm) SWIR (900 - 1700 nm) MWIR (3 - 5 μm) LWIR (8 -14 μm)

Phasics Kaleo MultiWAVE test station

Phasics is innovating in optical metrology with a new instrument able to measure both transmitted and reflected wavefront error (TWE/RWE). Coated and uncoated optics can be qualified over a diameter of 5.1 inches (130 mm) at their working wavelengths. The Kaleo MultiWAVE is an advantageous alternative and cost-effective solution to the purchase of several interferometers. The system offers a measurement accuracy comparable to Fizeau interferometry.

Key Features

  • Any wavelength on demand: UV - VISIBLE - NIR - SWIR - MWIR - LWIR
  • Multiple wavelenghts on the same test bench
  • Nanometric phase resolution and large dynamics (> 500 fringes)

Applications

Optics metrology and optical system alignment

PERFORMANCES (1)

RMS repeatability (2) < 0.7 nm (< λ / 900)
Sample reflectivity range ~4% - 100%

(1) On a 4″ pupil size, with a 625 nm source
(2) 36 sequential measurements are performed on a 4” reference mirror, each being averaged 16 times. A reference is defined as the average of all odd numbered measurements. RMS repeatability is then defined as the average RMS difference plus 2 times the standard deviation of the difference between even numbered measurements and the reference.
