An objective lens is used for DNA sequencing. An example system includes a flow cell, the objective lens, and a camera. Light from the flow cell is imaged by the camera through the objective lens. The objective lens can provide a long working distance; a flat field curvature; a high numerical aperture; and/or a wide field of view.

This invention comprises a system and a method for inspecting the inside of delayed petroleum coking vessels to identify deformations, detect and determine the severity of other defects, and visually observe the inside of the inspected vessel.

An inspection device (1) includes a light source (10) projecting excitation light to an inner surface of a container (20); an imager (11) capturing a fluorescence image of fluorescence emitted from a foreign substance in response to the excitation light projected; and a detector (13) detecting the foreign substance adhering to the inner surface of the container from the fluorescence image captured by the imager. The foreign substance contains a material emitting fluorescence in response to the excitation light projected to the material. The detector includes a calculator (14) calculating an average brightness value in an inspection target region, and an adjuster (15) adjusting an image-capturing condition where the fluorescence image is captured such that the average brightness value falls within a preset range.

A device for inspecting containers which have an opening includes a transport device which transports the objects along a configured transport path. The device includes a monitoring device which is configured to monitor at least one region of an inner wall of the container through the opening. The monitoring device is configured to capture spatially resolved images, and has a lighting device configured to illuminate at least one region of the inner wall, is arranged between the monitoring device and the container.

A method includes determining, using a processing device, a set of observations from coolant data, the coolant data being received from one or more sensors in an environment associated with a coolant. The method further includes determining, using a machine learning model and the set of observations, a contamination level of the coolant. The method also includes initiating an operation, using the processing device, responsive to determining the coolant contamination level.

An umbilicus-driven centrifuge includes a yoke configured to orbit a midsection of the umbilicus around a rotational axis at a first speed so as to cause a separation chamber associated with the umbilicus to rotate about the rotational axis at a second speed that is approximately double the first speed. An optical monitoring system directly monitors the separation chamber, with a light source oriented to emit light toward the separation chamber and a light detector oriented to receive at least a portion of the light after the light has passed through the separation chamber. A controller receives a plurality of signals from the light detector, then compares the period or frequency of the signals to an expected period or frequency. The controller determines that the umbilicus is experiencing an irregularity when the period or frequency is different from the expected period or frequency.

An arrangement for inspecting a container and a method for inspecting a container. The arrangement is also directed to software and a device for carrying out the inspecting wherein the method for inspecting includes receiving image data on a container, verifying the location and/or position data of the image data in relation to the container, analyzing the received image data, and detecting possible damage points.
