著名的反射鏡製造者約翰多布森先生經常利用距離他住屋數座之外的街燈進行星點測試他的反射鏡。On the determination of errors in thin lens ' focal distance
對測定薄透鏡焦距誤差的探討In the retrofocus project, a retrofocus structure with two elements is used in the object lens to enlarge fov and back working distance, in the head of which the negative meniscus have the effect of balancing aberration and deviating rays like a prism. and a standard hyperhemisphere immersion lens with high refractive index is put behind the object lens to satisfy the receiving of a detector with smaller photosensitive
反遠距設計方案中物鏡採用二片式反遠距結構,增大了視場和后工作距離,彎月型負透鏡在前,具有平衡像差和棱鏡的偏向作用;物鏡後放置高折射率標準超半球型浸沒透鏡,滿足小光敏面探測器接收。If the objective lens is closer to the compact disk than the focal length of the object lens, then the cylindrical lens creates an elliptical image on the photodetector array
如果物鏡與光盤之間的距離短於物鏡的焦距,柱面透鏡就會使在光電探測器陣列上的成像變成橢圓影像。If the objective lens is further away from the compact disk than the focal length of the object lens, then the cylindrical lens again creates an elliptical image on the photodetector array
如果物鏡與光盤之間的距離長於物鏡的焦距,柱面透鏡也會使在光電探測器陣列上的成像變成橢圓影像。Of course, if the disk is right at the focal length of the objective lens, then the cylindrical lens does not affect the image and it is perfectly circular
當然,如果正好處於物鏡焦距位置,柱面鏡就不會影響到光電探測器上的成像,因而會獲得一個完美的圓性影像。Contact lenses. determination of back vertex power. method using focimeter with manual focusing

除了幾百光年內的星體外,天文學家很主要倚靠測量造父變星來計算天體的距離,利用地面望遠鏡測量造父變星,可直接給出約二三千萬光年內星體的距離,而對于更遙遠的星體,天文學家便要藉助其他方法,但這些方法還是需要利用造父變星來作校正。Stores photographic data of up to 7 rolls of 36 exposures on aperture, lens focal length, exposure compensation exposure bracketing increments, shutter speed, flash compensation flash bracketing increments ( including flash on off status ), exposure mode, and metering mode
