Conducting workplace incident investigations that are fair, timely, thorough and effective is essential to a good work environment. Proper investigations protect your employees’ safety and well-being, promotes a disruption-free workplace and can even save your organization’s reputation in the wake of an incident. The optical microscope, often referred to as the light microscope, is a type of microscope that commonly uses visible light and a system of lenses to magnify 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.Basic optical microscopes can be very simple, although many complex designs aim

For example, suppose the radiant energy entering the sample is 100 and the energy leaving is 48. The transmittance formula becomes:

The light wave could be reflected by the object. And the light wave could be transmitted by the object. Rarely however does just a single frequency of light strike an object. While it does happen, it is more usual that visible light of many frequencies or even all frequencies is incident towards the surface of objects.

Jan 17, 2018 · NCERT Class 10 Science Lab Manual – Refraction Through Glass Slab. Introduction. Refraction: When light travels from one medium to another, it generally bends,this bending is called refraction. Snell’s law: The law of refraction is also known as Snell’s law. Snell’s law gives the relationship between angles of incidence and angle of refraction. Fluorescence spectroscopy (also known as fluorimetry or spectrofluorometry) is a type of electromagnetic spectroscopy that analyzes fluorescence from a sample. It involves using a beam of light, usually ultraviolet light, that excites the electrons in molecules of certain compounds and causes them to emit light; typically, but not necessarily, visible light.

Incident Light . Incident light is the light that falls on a subject, either directly or indirectly. Direct sources of incident illumination are sources that emit light, like the sun or a strobe unit aimed at the subject. Indirect sources of incident illumination redirect light onto the subject. Reflected light microscopy is often referred to as incident light, epi-illumination, or metallurgical microscopy, and is the method of choice for fluorescence and for imaging specimens that remain opaque even when ground to a thickness of 30 micrometers.
