Twyman effect in thin curved optics: effects of variable thickness and curvature.
Lakshmanan SN, Lambropoulos JC. Lakshmanan SN, et al. Appl Opt. 2021 Feb 20;60(6):1780-1789. doi: 10.1364/AO.417081. Appl Opt. 2021. PMID: 33690519
Grinding or finishing of thin curved optics introduces surface-localized stresses that may result in bending deformations, thus affecting optical performance (Twyman effect). The Twyman effect depends on local thickness of the optic as well as its curvature. ...

Robust, motion-free optical characterization of samples using actively-tunable Twyman-Green interferometry.
Imeri A, Reza SA. Imeri A, et al. Sci Rep. 2023 Apr 7;13(1):5678. doi: 10.1038/s41598-023-32791-2. Sci Rep. 2023. PMID: 37029205 Free PMC article.
Unlike thickness/refractive index measurements with conventional Twyman-Green interferometers, the actively-tunable interferometer enables bulk-motion free thickness or refractive index sample measurements. ...The elimination of bulk motion from the measurement process pro …

Simultaneous thickness and phase index measurements with a motion-free actively tunable Twyman-Green interferometer.
Reza SA, Imeri A. Reza SA, et al. Appl Opt. 2023 May 20;62(15):3948-3958. doi: 10.1364/AO.489084. Appl Opt. 2023. PMID: 37706705
In this paper, we present a scheme to simultaneously measure the thickness and refractive index of parallel plate samples, involving no bulk mechanical motion, by deploying an electronically tunable Twyman-Green interferometer configuration. The active electronic control w …

Twyman effect mechanics in grinding and microgrinding.
Lambropoulos JC, Xu S, Fang T, Golini D. Lambropoulos JC, et al. Appl Opt. 1996 Oct 1;35(28):5704-13. doi: 10.1364/AO.35.005704. Appl Opt. 1996. PMID: 21127579
In the Twyman effect (1905), when one side of a thin plate with both sides polished is ground, the plate bends: The ground side becomes convex and is in a state of compressive residual stress, described in terms of force per unit length (Newtons per meter) induced by grind …

Estimation of an uncertainty budget and performance measurement for a dual-wavelength Twyman-Green interferometer.
Ibrahim DGA. Ibrahim DGA. J Microsc. 2021 Jun;282(3):224-238. doi: 10.1111/jmi.12997. Epub 2021 Jan 29. J Microsc. 2021. PMID: 33443302
The measurement has been applied to nominal step heights of 1.34 and 1.50 mum using a dual-wavelength Twyman-Green interferometer. Experimental results show that the measured step heights match with their nominal values with expanded uncertainty in the range of 5% from the …
