A system for evaluating the modulation transfer function (MTF) of a device under test is provided. The system includes an image projector configured to provide light in a pattern representing a desired image. The system further includes a lens configured to direct the provided light toward the device under test as a collimated beam. An image analysis component calculates the MTF for the device under test from the at least one image taken at the device under test and the known characteristics of the image projector and the lens.

A binocular device for visualizing optical radiation comprises a support structure, a left camera, and a right camera coupled to the support structure. The left camera comprising left optics and a left image sensor, the right camera comprising right optics and a right image sensor, the left image sensor and the right image sensor being configured to create left and right video signals from detected optical radiation received from the corresponding left and right input optics about a same field of view along respective left and right input optical axes. A specular reflection is detected.

A microscope apparatus includes a sample carrying module, a light source module and a lens module. The sample carrying module includes an adhesive element and a body having a light-transmission region and a sample viewing surface. The adhesive element is detachably adhered to the body, and at least partially covers the light-transmission region, such that the adhesive element is disposed adjacent to the sample viewing surface. The light source module is detachably disposed at a side of the body, and includes a base and a light source. The base has an aperture, and the sample carrying module is detachably disposed at a side of the aperture. The light source is disposed in the base. The lens module includes at least one lens, which is detachably disposed at one side of the sample carrying module and substantially focuses at the sample viewing surface, and corresponds to the light source module.

A user-wearable illumination assembly comprising eyeglass frames supporting a pair of lenses, a mounting structure on a bridge of the eyeglass frames, a headlamp removably coupled to the mounting structure, a battery housing removably coupled to the headlamp, and a battery inside the battery housing.

Provided herein are disclosures relating to systems and methods of detangling jewelry. The jewelry detangling system may include a body, the body further including a cavity and a plurality of arms located in a cavity of the body and operably coupled therein. The plurality of arms further include corresponding beds dimensioned to receive jewelry pieces thereon during the detangling process. A magnifier including a frame and a lens may be coupled to the body of the jewelry detangler and rotatable about a hinge thereon about a plurality of positions.

Article of jewelry includes a main frame defining a cutout in a medial portion thereof, a magnifying glass received within the cutout, and a light source configured to disperse light proximal to the magnifying glass. The main frame comprises a first configuration where the main frame is pivoted inwardly to form a bracelet orientation, and a second configuration in which the main frame is pivoted outwardly to form a magnifying orientation.
