They use mirrors and lenses to reflect and refract light and form images. The light microscope and telescope use convex lenses and mirrors to make enlarged images of very tiny or distant objects. A camera uses a convex lens to … Continue reading →

‘High’ or ‘Fine’ gives the best quality but the biggest files, ‘Medium’ or ‘Normal’ gives decent quality but smaller files, while ‘Low’ or ‘Basic’ means very small files but a visible quality loss. We always recommend ‘Fine’ quality for JPEGs … Continue reading →

SEMs provide a 3D image of the surface of the sample, whereas TEM images are 2D projections of the sample, which in some cases makes the interpretation of the results more difficult for the operator. Does TEM produce a 2D … Continue reading →

MICROSCOPE– A Microscope is an instrument basically used for seeing smaller objects, lenses are used in the microscope to make smaller objects to appear larger. The object to be viewed under the microscope is referred to as the specimen. What … Continue reading →

A projection lens is the part of a projector that magnifies an image and casts it onto a screen. These lenses typically feature multiple lens elements and come in two main types: zoom and fixed focus. What is projector lens … Continue reading →

The main difference between SEM and TEM is that SEM creates an image by detecting reflected or knocked-off electrons, while TEM uses transmitted electrons (electrons that are passing through the sample) to create an image. What are similarities and differences … Continue reading →

If you want to change your eye color, opt for a non-invasive, temporary change, such as using tinted contacts. Wearing prescription or decorative contacts may come with some risks, but contacts can be far safer than going under the knife. … Continue reading →

The ISO value indicates a camera sensor’s sensitivity to light. The lower the ISO number, the less sensitive the sensor is to light. High ISO values, on the other hand, mean that quality images can be created even in low … Continue reading →

A social lens refers to how a person views a given situation. There are many factors that go into developing a person’s social lens or perception of the world. Race, culture, religion, and economic status are just some of the … Continue reading →

To calculate the total magnification of the compound light microscope multiply the magnification power of the ocular lens by the power of the objective lens. For instance, a 10x ocular and a 40x objective would have a 400x total magnification. … Continue reading →

Psychoanalytic criticism adopts the methods of “reading” employed by Freud and later theorists to interpret texts. It argues that literary texts, like dreams, express the secret unconscious desires and anxieties of the author, that a literary work is a manifestation … Continue reading →

Aperture sizes are measured by f-stops. A high f-stop like f/22 means that the aperture hole is very small, and a low f-stop like f/1.8 means that the aperture is wide open. Is 1.8 A high aperture? Minimum and Maximum … Continue reading →

Yet even an objective robot can have different focuses, thus there are three different formalist lenses: New Criticism, structuralism, and deconstruction. What are the lenses of criticism? The different literary lenses that remain in use fall into four general categories: … Continue reading →

Speed Booster® physically reduces focal length and increases maximum aperture (smaller f-number) of the lens. The “35mm equivalent focal length” is not a focal length at all, but a measure of field of view (FoV). Does Metabones change focal length? … Continue reading →
