Optical equipment

  1. 1. OPTICAL EQUIPMENT <ul><li>By Roesyah </li></ul>
  2. 2. OPTICAL EQUIPMENT <ul><li>Eye </li></ul><ul><li>glasses </li></ul><ul><li>magnifying glass </li></ul><ul><li>camera </li></ul><ul><li>microscope </li></ul><ul><li>binoculars </li></ul>
  3. 3. Eye <ul><li>Eyes are one of the human senses of vision that serves as a tool . </li></ul><ul><li>Parts of the eye is important, among others; aquaeus humor, accommodation muscle, eye lens, cornea, pupil, iris, retina, vitreous humor, yellow spots, blind spots, and optic nerve . </li></ul><ul><li>Defects in the eye include: 1. Myopia (nearsightedness) 2. Hipermetropi (farsightedness) 3. Presbiopi (old currency) 4. astigmatism </li></ul>
  4. 4. glasses <ul><li>Glasses are optical devices that serve as visual aids in eye defects. For example Astigmatism eye defects assisted by cylindrical glasses. </li></ul>
  5. 5. Loop (magnifying glass) <ul><li>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: </li></ul><ul><li>For maximum eye berakomodasi s' = -25 cm (negative sign (-) indicates a shadow in front of the lens) to obtain: </li></ul>
  6. 6. camera <ul><li>The camera is a tool used to produce a photographic image on the film negative. </li></ul><ul><li>The camera consists of several parts, namely: Convex lens Diaphragm Aperture Plates film The nature of the shadow: 1. real 2. inverted 3. minimized </li></ul>
  7. 7. microscope <ul><li>microscope 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 </li></ul>
  8. 8. <ul><li>microscope observations   Microscope observations are divided into; a. microscope observation without accommodation: M = (Sob '/ Sob) x (Sd / Fok) b. Microscope observations with maximum accommodations:       M = (Sob '/ Sob) x [(Sd / Fok) +1] </li></ul>
  9. 9. Binoculars <ul><li>Binoculars or a telescope is used to observe the optical objects are very far to look more closely and clearly. </li></ul><ul><li>1) Binocular Star </li></ul><ul><li>Bias-Binocular s </li></ul><ul><li>Binoculars-reflection 2.) Field Binoculars (Binoculars Earth) </li></ul>
  10. 10. evaluation <ul><li>A 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! </li></ul>
  11. 11. <ul><li>Answer : Objects located on the right </li></ul><ul><li>eyepiece focal point fob = 3 cm Fok = 4 cm d = 25 cm where d = S'ob because Sok + Sok = Fok = 4 cm So: 25cm = S'ob + 4 cm S'ob = 21 cm Eyes not berakomodasi: </li></ul>
  12. 12. thank you....
