Meadowlark Optics has excellent capabilities for transmission, reflection and polarization behavior metrology from the UV to the Mid-Wave IR.
Meadowlark Optics has been a leader in polarization optics for more than 40 years, with award winning products and outstanding metrology capabilities, setting us apart from the competition. Below are some of our measurement capabilities:
1. Retardance vs WL scans: 380 – 1700 nm, WL resolution down to 0.1 nm.
2. Oblique incidence retardance measurements: up to 40° incidence angle, 0°-180° azimuth.
3. Retardance vs voltage (0-20 V) for liquid crystal retarders.
4. Retardance vs temperature: 20–75°C, up to 2” diameter aperture.
5. Low retardances: down to 2 nm retardance at 630 nm wavelength.
6. Elliptical retardance measurements: linear and circular retardance components.
