Disclosed is a broadband objective lens and a method of manufacturing the objective lens. The objective lens includes a plurality of lenses, and each of the lenses includes a coating layer on which a nanopattern is formed.

Broadband objective lens with anti-reflective nanoparticles and manufacturing method thereof

Provided is a fast parallel optical coherence tomographic image generating method including dispersing light into N spectral regions &#x394;&#x3bb;through &#x394;&#x3bb;sequentially from a low frequency wavelength to a high frequency wavelength, the light being emitted from a broadband light source of a fast parallel optical coherence tomographic image generating apparatus, N being an integer greater than or equal to 2, splitting the light emitted from the broadband light source to be incident on a sample and a reference mirror, partitioning the sample into N image regions Pthrough P, discretely controlling a beam scanner such that the light emitted from the broadband light source is incident on the sample at a position changed by a preset distance, acquiring an interference spectral image through interference light formed in response to interference of measurement light and reference light, and generating a tomographic image of the sample using the interference spectral image.

Fast parallel optical coherence tomographic image generating apparatus and method

Provided is a solid immersion lens (SIL) holder for optical axis precision correction of a high resolution optical microscope, equipped with a SIL and an objective lens barrel equipped with a plurality of objective lenses, the SIL holder comprising: a circular flange providing in the middle of the objective lens barrel to be coupled to the SIL holder; a coupling flange formed at one end portion thereof and coupled to the circular flange; a conical tube formed at the other end portion thereof, the SIL being mounted onto a lower end portion of the conical tube, wherein the SIL holder comprises an optical axis adjusting part which adjusts such that the central axis of the SIL approaches the central axis of an objective lens, and the SIL holder comprises an extension/contraction adjusting part which allows the SIL to be very close to a measurement surface of a specimen.

Solid immersion lens holder for high resolution optical microscope

Provided is a common-path optical fiber-based handheld parallel optical coherence tomography (OCT) apparatus, including a probe configured to receive the light from a broadband light source and illuminate a measurement target, wherein the probe may include an inner space through which the light passes, a collimator configured to collimate the light incident to the inner space, a diffraction grating configured to diffract the light having passed through the collimator, a galvanometer scanner configured to reflect the light having passed through the diffraction grating, an objective lens configured to concentrate the reflected light on a focal point, and an interferer configured to acquire an interfered light by reflecting at least a portion of the light having passed through the objective lens.

Common-path optical fiber-based handheld parallel optical coherence tomography (OCT) apparatus

Provided is an apparatus for fixing a solid immersion lens (SIL) in an optical system. The apparatus includes a first adapter; a second adapter screw-coupled to the inner surface of the first adapter and screw-coupled to the outer surface of a third adapter to pressurize a first O-ring; the third adapter screw-coupled to the inner surfaces of the second adapter and a fourth adapter; the fourth adapter screw-coupled to the outer surface of the third adapter to pressurize a second O-ring; the first and second O-rings elastically fixing an outer surface of a barrel of an infrared ray (IR) objective lens; and an SIL holder mounting the SIL onto the first adapter.
