An objective lens for an endoscope consists of a negative front group, an aperture stop, and a positive rear group that are arranged in this order from an object side. The front group includes only a negative first lens as a lens. The rear group includes only four lenses that consist of...
To solve the problem step by step, we will follow the outlined approach:Step 1: Understand the Setup We have a compound microscope consisting of an objective lens and an eyepiece lens. The focal lengths are given as: - Focal le
A compound microscope consists of an objective lens of focal length 1 cm and an eye piece of focal length 5 cm with a separation of 10 cm. The distance between an object and the objective lens, at which the strain on the eye is minimum is n40cm. The value of n is ___ View Sol...
In a simple microscope, an objective lens forms a real, magnified, and inverted image of an object. In a compound microscope, an eyepiece is added, forming a virtual image that is viewed by eye to give real image on the retina. The eye can be replaced by CCD camera to record moving ...
A compound optical microscope consists of lenses, such as an objective lens, an ocular lens, and a condenser lens. The resolution of a microscope is determined by the wavelength (λ) of the illumination light, the light collection angle (θ) of the objective lens, and the refractive index ...

The setup consists of a white light source or laser sources with wavelengths of 450, 532, and 635 nm; an objective lens (10×); and a CMOS image sensor. (b–d) Optical camera images showing the components, including the water container, for amphibious imaging. (e) Measured light ...
For example, a 100× objective lens with an NA of 0.8 and a working distance of 2 mm provides an FOV of 0.26 mm in diameter. Taking advantage of the broadband MRR detector, we further achieved high-axial resolution volumetric PAM imaging and quantified its voxel size by imaging a ...
The data format used is compatible with VTK and consists of multiple arrays: vertex positions and values, vertex indices, cell start indices, cell types, and cell values. An unstructured volume type is created by passing the type string “unstructured” to ospNewVolume. Sampled cell values can...
There is provided an optical head including (a) a laser source for emitting a light, (b) an objective lens for focusing the light onto a plane of an optical recording medium, (c) a photodetector inclu
