A hemocytometer. The two semi-reflective rectangles are the counting chambers. The hemocytometer (or haemocytometer, or Burker's chamber) is a counting-chamber device originally designed and usually used for counting blood cells. [1] The hemocytometer was invented by Louis-Charles Malassez and consists of a thick glass microscope slide with a ...
ANSI Z136.1 – Safe Use of Lasers; As the parent document of the Z136 series of laser safety standards, the Z136.1 is the foundation of laser safety programs for industry, military, research and development (labs), and higher education (universities). [9] ANSI Z136.2 – Safe Use of Optical Fiber Communication Systems Utilizing Laser Diode and ...
Transport by gravity using an upright microscope (called GAM, gravity-assisted microdissection) or transport by laser pressure catapult; the most recent generation utilizes a technology based on laser induced forward transfer (LIFT). With cut-and-capture, a cap coated with an adhesive is positioned directly on the thinly cut (5-8 μm) tissue ...
Microscopy. Scanning electron microscope image of pollen (false colors) Microscopic examination in a biochemical laboratory. Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye).

The sizes of viruses determined using this new microscope fitted in well with those estimated by filtration experiments. Viruses were expected to be small, but the range of sizes came as a surprise. Some were only a little smaller than the smallest known bacteria, and the smaller viruses were of similar sizes to complex organic molecules. [14]
Optical microscope. The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.
An operating microscope or surgical microscope is an optical microscope specifically designed to be used in a surgical setting, typically to perform microsurgery. [ 1 ] Design features of an operating microscope are: magnification typically in the range from 4x-40x, components that are easy to sterilize or disinfect in order to ensure cross ...
Endomicroscopy. Endomicroscopy is a technique for obtaining histology -like images from inside the human body in real-time, [1] [2] [3] a process known as ‘optical biopsy’. [4] [5] It generally refers to fluorescence confocal microscopy, although multi-photon microscopy and optical coherence tomography have also been adapted for endoscopic use.
