An optical instrument

  1. 1. An Optical Instrument will be presentation are .. E y e s  C a me r a D i g i t a l T e l e s c o p e  Mi c r o s c o p e
  2. 2. Myopia
  3. 3. Someone can see the object if someone have convex lens P=- 100/ PR P : Kuat lensa (dioptri) PR : Titik jauh (cm)
  4. 4. P = 100/x – 100/PP P : Kuat lensa (dioptri) PP: Titik dekat (cm) x : jarak yang ingin dibaca
  5. 5. Astigmatism is one where rays that propagate in two perpendicular planes have different focus. Astigmatism can help with cylindrical lens Astigma adalah dimana cahaya yang menyebarkan dalam dua bidang tegak lurus yang mempunyai fokus berbeda. Astigma bisa dibantu dengan lensa silinder
  6. 6. Cataract
  7. 7.  Kamera digital adalah alat untuk membuat gambar dari obyek untuk selanjutnya dibiaskan melalui lensa kepada sensor CCD (ada juga yang menggunakan sensor CMOS) yang hasilnya kemudian direkam dalam format digital ke dalam media simpan digital  Camera digital is instrument to make a picture from object to deflect through lens to sensor CCD (also able use with sensor CMOS) that output to record in format digital and then save in storage digital
  8. 8. Clasification of camera digital are :  Videos camera o Professional camera : usually use in channel television o Camcorder  Silent camera o Digital pocket camera o Camera digital prosumer o SLR digital (Single Lens Reflect digital)
  9. 9.      
  10. 10. Formula !!  Teropong bintang there are 2 lens fob >> fok Magnification angular (perbesaran sudut) : o Without accommodation M = f / f ob ok d = fob + fok o Accommodation maximum M = f / S ob ok d = fob + Sok
  11. 11. • Teropong bumi There are 3 lens objektive, ocular, inverted Magnification angular : o Without accommodation M = fob / fok d = fob + 4fp + fok o Accommodation maximum M = fob / Sok d = fob + 4fp + Sok
  12. 12. Microscope
  13. 13.
  14. 14. 1. Magnification objective lens 2. Magnification ocular lens a. Without accommodation Mok = Sn / fok Sok = fok b. Accomodation maximum Mok = Sn / fok + 1 Length of microscope (d) = S’ob + Sok to search value of Sok , used comparison 1/ = 1/ Sok - 1/ Sn fok 3. Quantity of magnification Mtot = Mob + Mok
