Abstract
Provided herein are interference objective modules comprising an objective, and an interference module comprising a reference plate disposed apart from the objective to provide a reference arm, a beam splitter to split a source light processed from the objective, and a sample plate to translate the split light from the beam splitter to provide a sample arm, wherein the interference module is configured to make a distance of a focal plane and an interference plane of the interference objective module varied during a measurement, and wherein the focal plane and the interference plane of the interference objective module intersect during the measurement.

An interference objective module comprising
- an objective, and
- an interference module comprising
- a reference plate disposed apart from the objective to provide a reference arm, a beam splitter to split a source light processed from the objective, and
- a sample plate to translate the split light from the beam splitter to provide a sample arm, wherein the interference objective module is filled with at least two different media with a refractive index similar to the sample, wherein the interference objective module comprises a first media filled in a space between the reference plate and the beam splitter;
- and a second media filled in a space between the beam splitter and the sample plate, wherein the first media comprises silicone oils, and the second media comprises silicone gels.
