Optical equipment

  1. 1. OPTICAL EQUIPMENT by : Roesyah (09330075)
  2. 2. OPTICAL EQUIPMENT Eye glasses magnifying glass camera microscope binoculars
  3. 3. Eye Eyes are one of the human senses of vision that serves as a tool. Parts of the eye is important, among others; aquaeus humor, accommodation muscle, eye lens, cornea, pupil, iris, reti na, vitreous humor, yellow spots, blind spots, and optic nerve.
  4. 4. Eye defectsDefects in the eye include: 1. Myopia (nearsightedness) 2. Hipermetropi (farsightedness) 3. Presbiopi (old currency) 4. astigmatism
  5. 5. glassesGlasses are optical devices that serve as visual aids in eye defects. For example Astigmatism eye defects assisted by cylindrical glasses.
  6. 6. Loop (magnifying glass)Loop is an optical instrument consisting of a convex lens to see small objects to appear more clear and magnified. The nature of the shadow on the loop that is virtual, erect and enlarged. Loop equation:
  7. 7. For maximum eye berakomodasi s = - 25 cm (negative sign (-) indicates a shadow in front of the lens) to obtain:
  8. 8. cameraThe camera is a tool used to produce a photographic image on the film negative. The camera consists of several parts, namely: Convex lens Diaphragm Aperture Plates film The nature of the shadow: 1. real 2. inverted 3. minimized
  9. 9. microscopemicroscope is an optical instrument used to see small objects that can not be seen directly by eye. microscope consists of two convex lenses, namely; a. lens obyektife b. ocular lens
  10. 10. microscope observations Microscope observations are divided into;a. microscope observation withoutaccommodation:M = (Sob / Sob) x (Sd / Fok)b. Microscope observations with maximumaccommodations: M = (Sob / Sob) x [(Sd / Fok) +1]
  11. 11. BinocularsBinoculars or a telescope is used to observe the optical objects are very far to look more closely and clearly. 1) Binocular Star Bias-Binoculars Binoculars-reflection 2.) Field Binoculars (Binoculars Earth)
  12. 12. evaluationA microscope has objekyive and eyepiece lens with a focal length of each 3cm and 4cm. The distance between the second lens is 25cm. Determine the amount of magnification of the microscope for the eye does not berakomodasi!
  13. 13. Answer:Objects located on the righteyepiece focal pointfob = 3 cmFok = 4 cmd = 25 cm where d = Sob becauseSok +Sok = Fok = 4 cmSo: 25cm = Sob + 4 cmSob = 21 cmEyes not berakomodasi:
