  • 45. • ตัวอย่าง เลนส์บางสองอัน อันหนึ่งมีกําลัง +8.00 d อีกตัวเป็นเลนส์เว้าไม่ทราบค่ากําลัง จัดให้มีแนว แกนทัศนร่วมกันและห่างกัน 8.00 cm ให้เป็นระบบ ที่ไม่มีจุดโฟกัส (คือแสงเข้าและออกเป็นแสงขนาน) ถ้ามีตัวจํากัดแสงเส้นผ่านศูนย์กลาง 15 มิลลิเมตร อยู่กึ่งกลางระหว่างเลนส์ทั้งสอง ก. จงหาตําแหน่งของเอนทรานซ์พิวพิล ข. จงหาตําแหน่งของเอกซิทพิวพิล ค. จงหาขนาดของทั้งสองพิวพิล Wednesday, July 24, 13
  • 46. 8.00 cm system matrix ของเลนส์ตัวแรกคือ ML1 = 1 +8.00 0 1 ⎛ ⎝⎜ ⎞ ⎠⎟ ทําให้ได้ความยาวโฟกัสของเลนส์แรกเป็น fL1 = 1 +8.00 =+0.1250m =+12.5cm fL1 fL2 ASL1 L2 Wednesday, July 24, 13
  • 47. ได้ความยาวโฟกัสของเลนส์ตัวที่สอง fL2 = fL1 − 8.00cm = 12.5 − 8.00 = 4.5cm แต่เนื่องจากอยู่ด้านขวา จึงกําหนดเครื่องหมายเป็นลบ และได้กําลังของเลนส์เป็น - 1 0.045 = -22.2d ทําการหา EP โดยเสมือนว่าหาตําแหน่งวัตถุที่เกิดภาพเป็น AS ด้วยเลนส์ L1 EP = n0 ⋅ M21 − M11 ′1 M12 ′1 − M22 ⎛ ⎝⎜ ⎞ ⎠⎟ ML2 = 1 −22.2 0 1 ⎛ ⎝⎜ ⎞ ⎠⎟ Wednesday, July 24, 13

  • 50. ช่องเปิดสัมพัทธ์ Relative aperture • พลังงานที่ตกกระทบต่อพื้นที่ภาพ • คือช่องเปิดสัมพัทธ์ • คือตัวเลขเอฟ (f-number) บางทีเขียนเป็น f/# ∝ D f ⎛ ⎝⎜ ⎞ ⎠⎟ 2 D f f D Wednesday, July 24, 13
  • 51. Wednesday, July 24, 13
  • 52. ช่องเปิดเชิงตัวเลข N.A. Wednesday, July 24, 13
